Se hacen reaccionar 100 g del agente oxidante con 25 g del agente reductor, según la reacción REDOX LaTeX: N_2\left(g\right)+H_2\left(g\right)\longrightarrow NH_3\left(g\right)N 2 ( g ) + H 2 ( g ) ⟶ N H 3 ( g ) Indique el reactivo en exceso y los gramos de amoniaco formado, si la eficiencia del proceso es del 80 %
Answer:
El reactivo en exceso es hidrógeno
97.12g NH₃ son formados
Explanation:
Basados en la reacción:
N₂(g) + 3 H₂(g) → 2 NH₃(g)
El hidrógeno pasa de estado de oxidación 0 a estado de oxidación +1. Al perder un electrón se oxida y es el agente reductor.
El nitrógeno pasa de estado 0 estado -3. Al ganar 3 electrones se reduce y es el agente oxidante.
100g de N₂ son (Peso molecular: 28g/mol):
100g × (1mol / 28g) = 3.57 moles de N₂
Y 25g de H₂ son (Peso molecular: 2g/mol):
25g × (1mol / 2g) = 12.5 moles de H₂
Como 3 moles de hidrógeno reaccionan por mol de nitrógeno, las moles de nitrógeno que se necesitan para hacer reaccionar completamente 12.5 moles de hidrógeno son:
12.5 moles H₂× (1 mol N₂ / 3 moles H₂) = 4.17 moles de nitrógeno.
Como hay 3.57 moles de nitrógeno, el reactivo en exceso es hidrógeno.
Como el reactivo limitante es el nitrógeno y 1 mol de nitrógeno produce 2 moles de amoniaco, las moles de amoniaco son:
3.57 moles de N₂ × (2 moles NH₃ / 1 mol N₂) = 7.14 moles de NH₃
La masa producida idealmente es:
7.14 mol NH₃ ₓ (17g/mol) = 121.4 g de NH₃. Como la eficiencia del proceso es del 80%:
121.4 g NH₃ × 80% = 97.12g NH₃ son formados
Answer:
Excess reactant: H₂
Mass of produced ammonia, 97.1 g
Explanation:
Identify the reaction:
N₂ + 3H₂ → 2NH₃
We identify the reducing agent and the oxidizing agent:
N₂ changed the oxidation state from 0 to -3. This is the reduction, so it is the oxidizing agent. By the way the H₂ is the reducing agent.
We convert the mass to moles:
100 g / 28 g/mol = 3.57 moles of N₂
25 g / 2 g/mol = 12.5 moles of H₂
Ratio is 1:3. For 1 mol of nitrogen, we need 3 moles of hydrogen
Then, 3.57 moles of N₂ would need (3.57 . 3) / 1 = 10.7 moles
We have 12.5 moles of H₂, so the hydrogen is the excess reactant and the nitrogen is the limiting.
To produce ammonia, the reaction needs 1 mol of N₂, that can produce 2 moles of product
3.57 moles of N₂ will produce (3.57 . 2) / 1 = 7.14 moles of NH₃
As yield reaction is 80%, we will produce 7.14 mol . 0.80 = 5.71 moles
We convert the moles to mass: 5.71 mol . 17 g / 1mol = 97.1 g
What is the molar mass of Al2(SO4)3?
Answer:
342.14g/mol.
Explanation:
The molar mass of Al2 (SO4)3 is 342.15g/mole.
Reasons that one aluminum atom=26.98. Therefore two aluminum atoms:=2(26.98 g/mole) =53.96 g/mole.
Mass of SO4=96.06g/mol.
Therefore molar mass of Al2(SO4)3= 53.96+(96.06)×3=342.14g/mol
Answer:
342.17 g/mol
Explanation:
Al= 26.98
S= 32.07
O= 16.00
To calculate that you would have
2(26.98) since there are two Als
and then you have to distribute the 3 to the S and O so...
3S and 12O
which is
3(32.07) + 12(16.00)
which means you add
2(26.98) + 3(32.07) + 12(16.00)
=53.96 + 96.21 + 192
=342.17
there you Go! the final answer is 342.17 g/mol.

A solution of Co(NO₃)₂ is electrolyzed using a 15.0A current for 1.00 hour and Co(s) is produced at the cathode. Calculate the moles of electrons that was used to electrolyze the solution? Calculate the moles and mass of Co(s) produced at the cathode?
Answer:
1. 0.56 mole of electron.
2. 0.28 mole of Co .
3. 16.52g of Co.
Explanation:
The following data were obtained from the question:
Current (I) = 15A
Time (t) = 1 hr = 1 x 60 x 60 = 3600secs
Next, we shall determine the quantity of electricity, Q flowing in electrolyte. This is illustrated below:
Quantity of electricity (Q) = current (I) x Time
Q = It
Q = 15 x 3600
Q = 54000C.
1. Determination of the moles of electrons used to electrolyzed the solution. This is illustrated below:
96500C = 1 mole of electron
Therefore, 54000C = 54000/96500 = 0.56 mole of electron.
Therefore, 0.56 mole of electron was used to electrolyze the solution.
2. Determination of the number of mole of Co produced at the cathode. This is illustrated below:
At the cathode:
Co2+ + 2e —> Co
From the balanced equation above,
2 moles of electron produce 1 mole of Co.
Therefore, 0.56 mole of electron will produce = 0.56/2 = 0.28 mole of Co.
Therefore, 0.28 mole of Co is produced at the cathode.
3. Determination of the mass of Co produced at the cathode. This can be achieved by doing the following:
Molar mass of Co = 59g/mol
Number of mole of Co = 0.28 mole
Mass of Co =..?
Mass = mole x molar mass
Mass of Co = 0.28 x 59
Mass of Co = 16.52g
Therefore, 16.52g of Co is produced at the cathode.
What is the yield of uranium from 2.50 kg U3O8?
Answer: Thus the yield of uranium from 2.50 kg [tex]U_3O_8[/tex] is 2.12 kg
Explanation:
According to avogadro's law, 1 mole of every substance weighs equal to molecular mass and contains avogadro's number [tex](6.023\times 10^{23})[/tex] of particles.
To calculate the number of moles, we use the equation:
[tex]\text{Number of moles}=\frac{\text{Given mass}}{\text{molar mass}}[/tex]
moles of [tex]U_3O_8=\frac{2.50\times 1000g}{842g/mol}=2.97mol[/tex] (1kg=1000g)
As 1 mole of [tex]U_3O_8[/tex] contains = 3 moles of U
2.97 mole of [tex]U_3O_8[/tex] contains = [tex]\frac{3}{1}\times 2.97=8.91moles[/tex] moles of U
Mass of Uranium=[tex]moles\times {\text {Molar mass}}=8.91mol\times 238g/mol=2120g=2.12kg[/tex]
( 1kg=1000g)
Thus the yield of uranium from 2.50 kg [tex]U_3O_8[/tex] is 2.12 kg

Which ion can be both an oxidizing agent and reducing agent?
A) Sn2+
B) Cu2+
C) Al3+
D) Fe3+
Answer: a) Sn 2+
Explanation:A reducing agent is a substance that can be oxidized when it loses electrons while An oxidizing agent is a substance that is reduced when it gains electrons.
Considering Cu 2+, Fe 3+, Al 3+, Here, Cu 2+ can be reduce to its Copper metal, same for Al 3+ to Aluminium metal and Fe 3+ to Fe 2+ ion and will not be oxidized further since they are in their most oxidized states. The three ions are acting as only oxidizing agents.
while Sn 2+ can be oxidized to become Sn 4+ and also be reduced to become Sn metal acting as a reducing agent and an oxidizing agent.

A solution is made by mixing 114.g of benzene C6H6 and 83.g of acetyl bromide CH3COBr. Calculate the mole fraction of benzene in this solution. Round your answer to 3 significant digits.
A solution is made by mixing 114.g of benzene C6H6 and 83.g of acetyl bromide CH3COBr, the mole fraction of benzene in this solution is 1.45mol.
What is molar mass ?The term molar mass is defined as the compound is often calculated by adding the quality atomic masses in g/mol of the constituent atoms.
Molar mass of CH3COBr,
Molar Mass = 2 × MM(C) + 3 × MM(H) + 1 × MM(O) + 1 × MM(Br)
= 122.944 g/mol
Molar mass of C6H6,
MM = 6 × MM(C) + 6 × MM(H)
= 6 × 12.01 + 6 × 1.008
= 78.108 g/mol
n(CH3COBr) = mass/molar mass
= 83 /122.944
= 0.675
n(C6H6) = mass/molar mass
= 114 / 78.108
= 1.45
n(CH3COBr),n1 = 0. 675mol
n(C6H6),n2 = 1. 45mol
Thus, the mole fraction of benzene in this solution is 1.45mol.

What are the conditions for evaporation?
Answer:
For evaporation you need a warm, preferably humid temperature. The rate of evaporation increases with an increase in temperature. A windy climate is best, as wind helps to remove the evaporated water vapour, and therefore creating a better scope for evaporation to continue. The speed of wind is important for evaporation because the wind pulls in dry air, increasing the rate of evaporation.
Short Answer- Hot and humid temperature, lots of wind speed.
Answer:
Explanation:
1 Evaporation is the phase change of a liquid to a gas. There are three very important requirements for evaporation to take place, 1) available energy, 2) available water, and 3) a vertical moisture gradient. Approximately 600 calories of heat must be added to a gram of water for it to evaporate into the air.
2. Evaporation is the process of a substance in a liquid state changing to a gaseous state due to an increase in temperature and/or pressure. It is a fundamental part of the water cycle and is constantly occurring throughout nature.
3.Water evaporates faster if the temperature is higher, the air is dry, and if there's wind. The same is true outside in the natural environment. Evaporation rates are generally higher in hot, dry and windy climates.

mol/l LiOH solution (5 points)
Answer: The volume of a 0.10 mol/l HCl solution needed to neutralize 10 ml of a 0.15 mol/l LiOH solution is 15 ml
Explanation:
To calculate the volume of acid, we use the equation given by neutralization reaction:
[tex]n_1M_1V_1=n_2M_2V_2[/tex]
where,
[tex]n_1,M_1\text{ and }V_1[/tex] are the n-factor, molarity and volume of acid which is [tex]HCl[/tex]
[tex]n_2,M_2\text{ and }V_2[/tex] are the n-factor, molarity and volume of base which is LiOH.
We are given:
[tex]n_1=1\\M_1=0.10mol/L\\V_1=?mL\\n_2=1\\M_2=0.15mol/L\\V_2=10mL[/tex]
Putting values in above equation, we get:
[tex]1\times 0.10\times V_1=1\times 0.15\times 10\\\\V_1=15mL[/tex]
Thus the volume of a 0.10 mol/l HCl solution needed to neutralize 10 ml of a 0.15 mol/l LiOH solution is 15 ml
. Act 20 g Ca (M = 40g / mol) with H2SO4 diluted within 10 seconds. What will be the rate of hydrogen formation in mol / sec. please
Answer:
Rate of hydrogen formation is 0.05 mole per second
Explanation:
Firstly, we write the equation of reaction.
When alkali earth metals react with dilute mineral acid, the reaction is vigorous with the production or evolution of hydrogen gas as a result of the displacement of the hydrogen from the acid by the metal. This is one of the basic reactions of mineral acids
Ca + H2SO4 ——> CaSO4 + H2
Looking at the reaction, 1 mole of calcium gave 1 mole of the hydrogen gas
What we do now is to calculate the number of moles of calcium produced by 20g of Ca
Mathematically;
number of moles = mass/atomic mass
number of moles of calcium is thus
20/40 = 0.5 moles
Now, if 1 mole of calcium produced 1 mole of the gas
Definitely, 0.5 mole of calcium will produce 0.5 mole of the gas
So the rate of gas formation would be 0.5/10 = 0.05 mole/second

Answer: The percent yield for the [tex]NaBr[/tex] is, 86.7 %
Explanation : Given,
Moles of [tex]FeBr_3[/tex] = 2.36 mol
Moles of [tex]NaBr[/tex] = 6.14 mol
First we have to calculate the moles of [tex]NaBr[/tex]
The balanced chemical equation is:
[tex]2FeBr_3+3Na_2S\rightarrow Fe_2S_3+6NaBr[/tex]
From the reaction, we conclude that
As, 2 moles of [tex]FeBr_3[/tex] react to give 6 moles of [tex]NaBr[/tex]
So, 2.36 moles of [tex]FeBr_3[/tex] react to give [tex]\frac{6}{2}\times 2.36=7.08[/tex] mole of [tex]NaBr[/tex]
Now we have to calculate the percent yield for the [tex]NaBr[/tex].
[tex]\text{Percent yield}=\frac{\text{Experimental yield}}{\text{Theoretical yield}}\times 100[/tex]
Experimental yield = 6.14 moles
Theoretical yield = 7.08 moles
Now put all the given values in this formula, we get:
[tex]\text{Percent yield}=\frac{6.14mol}{7.08mol}\times 100=86.7\%[/tex]
Therefore, the percent yield for the [tex]NaBr[/tex] is, 86.7 %

The octane number of fuel is 79%. What does that mean
Answer:
Octane number, measure of the ability of a fuel to resist knocking when ignited in a mixture with air in the cylinder of an internal-combustion engine.
Octane number is also known as octane rating. Octane numbers are based on a scale on which isooctane is 100 (minimal knock) and heptane is 0 (bad knock). The higher the octane number, the more compression required for fuel ignition. Fuels with high octane numbers are used in high performance gasoline engines.

Draw an alkyl bromide with proper stereochemistry that can be used to synthesize the given alkene as the exclusive product via an e2 reaction.
Answer:
See explanation below
Explanation:
You forgot to put the picture to do so. In this case, I manage to find one, and I hope is the one you are looking for. If not, then post it again and I'll gladly help you out again.
According to the picture with the answer, we have a cyclohexane with 4 methyl groups there. Two of them are facing towards the molecule with a darker bond. This means that the alkyl bromide, should have a bromine in one of the bonds, and in order to produce an E2 reaction, this bromine should be facing in the opposite direction of the methyl groups which are facing towards. This is because an E2 reaction occurs with the less steric hindrance in the molecule. If the bromine is in the same direction as the methyl group, it will cause a lot more of work to do a reaction, and therefore, an E2 reaction. I will promote instead a E1 or a sustitution product.
Therefore the alkyl bromide should be like the one in the picture 2.

If 1.50 L of 0.780 mol/L sodium sulfide is mixed with 1.00 L of a 3.31 mol/L lead(II) nitrate solution, what mass of precipitate would you expect to form?
Answer:
336.1 g of PbS precipitate
Explanation:
The equation of the reaction is given as;
Na2S(aq) + Pb(NO3)2(aq) ----> 2NaNO3(aq) + PbS(s)
Ionically;
Pb^2+(aq) + S^2-(aq) -----> PbS(s)
Number of moles of sodium sulphide= concentration of sodium sulphide × volume of sodium sulphide
Number of moles of sodium sulphide= 0.780 × 1.5 = 1.17 moles
Number of moles of lead II nitrate= concentration of lead II nitrate × volume of lead II nitrate
Number of moles of lead II nitrate= 3.31× 1.00= 3.31 moles
Then we determine the limiting reactant. The limiting reactant yields the least amount of product.
Since 1 moles of sodium sulphide yields 1 mole of lead II sulphide
1.17 moles of sodium sulphide also yields 1.17 moles of lead II sulphide
Hence sodium sulphide is the limiting reactant.
Thus mass of precipitate formed= amount of lead II sulphide × molar mass of sodium sulphide
Molar mass of lead II sulphide= 287.26 g/mol
Mass of lead II sulphide = 1.17 moles × 287.26 g/mol
Mass of lead II sulphide= 336.1 g of PbS precipitate

Answer:
They all have the same number of molecules or atoms which is 3.011*10²⁴ molecules or atoms.
5 moles of O = 3.011*10²⁴ molecules or atoms
5 moles of N = 3.011*10²⁴ molecules or atoms
5 moles of MgCl2 = 3.011*10²⁴ molecules or atoms
5 moles of C2H3NO = 3.011*10²⁴ molecules or atoms.
Explanation:
a)
5 moles of O = ?
1 mole of any substance is equal to Avogadro's number which is equal to 6.022×10²³molecules or atoms
From the question above,
5 moles of O = 5 × 6.022*10²³ = 3.011×10²⁴atoms or molecules.
b)
5 moles of N
From the same principle or fundamentally stated fact above,
1 mole of any substance = 6.022*10²³molecules or atom
5 moles of N = 5 × 6.024
2*10²³ = 3.011*10²⁴atoms or molecules.
c)
5 moles of MgCl₂
Same principle we used in a and b,
1 mole of any substance = 6.022*10²³ atoms or molecules
5 moles of MgCl2 = 5.0×6.022*10²³ = 3.011*10²⁴ atoms or molecules.
d)
5 moles of C₂H₃NO = ?
1 mole of C₂H₃NO = 6.022*10²³molecules or atoms
5 moles = x molecules or atoms
x = 5 × 6.024
2*10²³ = 3.011*10²⁴ atoms or molecules
What this proves is that no matter the compound, molecule or element, as long as they have equal amount of moles, they'll have the same number of atoms, molecules or particles.
Answer:
a. 3.011x10²⁴ atoms of O in 5 moles.
b. 3.011x10²⁴ atoms of N in 5 moles.
c. 3.011x10²⁴ atoms of MgCl₂ in 5 moles.
d. 3.011x10²⁴ atoms of C₂H₃NO in 5 moles
Explanation:
A mole is defined as the number of atoms in exactly 12.000g of ¹²C.
This number is equal to 6.022x10²³. That means 1 mole is equal to 6.022x10²³.
Thus:
a. O . 5 moles of oxygen (An atom) are:
5 moles O ₓ (6.022x10²³ atoms of O / mole) = 3.011x10²⁴ atoms of O in 5 moles
b. N . Also, 5 moles of nitrogen are:
5 moles N ₓ (6.022x10²³ atoms of N / mole) = 3.011x10²⁴ atoms of N in 5 moles
c. MgCl₂ . Magnesium chloride is a molecule. Again, 1 mole of MgCl₂ contains 6.022x10²³ molecules and 5 moles are:
5 moles MgCl₂ ₓ (6.022x10²³ molecules of MgCl₂ / mole) = 3.011x10²⁴ atoms of MgCl₂ in 5 moles
d. C₂H₃NO. 5 moles of C₂H₃NO are:
5 moles C₂H₃NO ₓ (6.022x10²³ molecules of C₂H₃NO / mole) = 3.011x10²⁴ atoms of C₂H₃NO in 5 moles
As you can see, number of molecules of 1 mole doesn't depend on the nature of the substance.
