If 12 grams of sodium reacts with 16 grams of chlorine, how much sodium chloride is Formed?
A. 4 g
B. 12 g
C. 28 g
D. 30 g

Answers

Answer:

6.576 g NaCl

Explanation:

2Na + Cl2 --> 2 NaCl

Step 1: Find out moles of Na and Cl to determine the limiting reactant:

moles Na = 12/23 = 0.52 moles Na

moles Cl2 = 16/71=0.225 moles Cl2

ratio Na:Cl is 2.3:1 so Cl is the limiting reactant.

Step 2: How many moles of NaCl are formed:

moles NaCl = moles Cl2 x (1 mol NaCl/2 moles Cl2) = 0.225/2 = 0.1125 moles NaCl

Step 3:

mass NaCl = moles NaCl x MM NaCl = 0.1125 x 58.45 = 6.576 g NaCl

A student is measuring the mass of a two metal cylinders. The following data is collected. The actual mass of each cylinder is given. Answer the following questions. Metal Cylinder A 12.4 grams Actual mass of metal cylinder A 12.7 g Metal Cylinder B 75.4 grams Actual mass of metal cylinder B 75.1 g a. What is the absolute error for the measurement of metal cylinders A and B

Answers

Answer:

Absolute error in measurement of A = 0.3

Absolute error in measurement of B = 0.3

Explanation:

Absolute error is a measure of the amount of error in a measurement i.e. a measure of how far away a measurement is from a true value or an indication of the uncertainty in a measurement.

The Absolute Error is the difference between the actual and measured value. In formula, the absolute error, Δx is given as:

Δx = |xi – x|,

Where:  xi is the measurement, x is the true value,

| | indicates that only absolute values are taken

In the measurements by the student in the question:

Metal Cylinder A

measured value = 12.4 grams

actual mass of metal cylinder A = 12.7 g

Using the absolute error formula; Δx = |xi – x|

Absolute error in measurement of A = |12.4 - 12.7| = 0.3

Metal Cylinder B

measured value = 75.4 grams

actual mass of metal cylinder B = 75.1 g

Using the absolute error formula; Δx = |xi – x|

Absolute error in measurement of B = |75.4 - 75.1| = 0.3

Calculate the number of moles in 15.5g of CaSO4.5H2O

Answers

Answer:

No. of moles = 0.0685

Explanation:

Given mass, m = 15.5g

We need to find the number of moles in 15.5 g of CaSO₄.5H2O

First, we find the mass of CaSO₄.5H2O.

M = (1×40)+(1×32)+(4×16)+(5×18)

M = 226 g/mol

We know that,

Number of moles = given mass/molar mass

[tex]n=\dfrac{15.5\ g}{226\ g/mol}\\\\n=0.0685\ \text{mol}[/tex]

Hence, there are 0.0685 moles in 15.5 g of CaSO₄.5H2O.

Why are acids called proton donors?

Answers

Acids are substances that can donate H+ ions to bases. Since a hydrogen atom is a proton and one electron, technically an H+ ion is just a proton. So an acid is a "proton donor", and a base is a "proton acceptor". The reaction between an acid and base is essentially a proton transfer.
The relationship between acids and bases is more aggressive than the donor/acceptor terminology implies. Bases don't passively "accept" protons; they rip hydrogen ions from acids. Acids don't "donate" hydrogen ions; they surrender them.

The increase in electro negativity when moving left to right on the periodic table can be explained by what?

Answers

Answer: Decrease in size

Explanation:

Electronegativity is defined as the property of an element to attract a shared pair of electron towards itself.

On moving across a period from left to right,   the size of an atom decreases because the electrons get added to the same shell and the nuclear charge keeps on increasing. Thus the electrons get more tightly held by the nucleus.

As, the size of an element decreases, the valence electrons come near to the nucleus. So, the attraction between the nucleus and the shared pair of electrons increases. Thus electronegativity increases.

HELPP

Answers

I’m thinking volcano cuz lava doesn’t move fast..-

Answer: D

Explanation:

Cause If you head to the middle of the ocean and dive down, down, down to where the Earth's plates meet, you might find an undersea mountain split by a deep trench. It's called a mid-ocean ridge. Up through such trenches, brand-new molten rock is bubbling. That's the newest rock on Earth! How does the ocean floor make room for all that new rock? Simply by pushing the old rock aside. In fact, the ocean floor is actually spreading right at this minute, out away from the deep trenches where new rock is being formed. The oldest rock can be found farthest away from the trenches, right up near the continents. It's all part of a process called seafloor spreading. It's been going on for millions of years (at the rate of a few centimeters per year), but scientists are just now getting to know more about it. In fact, because evidence of seafloor spreading was first discovered in the 1940s and 50s, your great-grandparents may have never heard of it!

Ultraviolet radiation and radiation of shorter wavelengths can damage biological molecules because they carry enough energy to break bonds within the molecules. A carbon-sulfur bond requires 272 kJ/mol to break. What is the longest wavelength of radiation with enough energy to break carbon-sulfur bonds

Answers

Answer:

439.7nm

Explanation:

Energy of a quantum can be calculated using below formula

E=hv...........eqn(1)

But v=λ/ c .........eqn(2)

If we substitute eqn(2) into eqn(1) we have

E= hc/(λ)

Where E= energy

h= Plank's constant= 6.62607004 × 10-34 m2 kg / s

c= speed of light

c= 2.998 × 10^8 m/s

λ= wavelength= ?

But the energy was given in Kj , it must be converted to Kj/ photon for unit consistency.

Energy E= 272 kJ/mol × 1mol/6.02× 10^23

Energy= 451.83× 10^-24 Kj/ photon

E= hc/(λ)...........eqn(1)

If we make λ subject of the formula

λ= hc/E

Then substitute the values we have

λ= [(6.626 × 10^-34) × (2.998 × 10^8)]/451.83× 10^-24

λ=(0.00043965) × (1Kj/1000J) × (10^9nm/1m)

λ=439.7nm

Hence, the longest wavelength of radiation with enough energy to break carbon-sulfur bonds is 439.7nm

Answers

Answer:

Explanation:

C

The limiting reactant in this reaction is Fe. 4 moles of Fe gives 2 moles of ferric oxide. Hence, 13 moles of Fe will give 6.5 moles of iron (iii)oxide.

What is limiting reactant ?

The reactant which is not sufficient in amount determines the yield of the reaction and it is called the limiting reactant of the reaction.

In the given reaction, 4 moles of iron reacts with 3 moles of oxygen to give 2 moles of iron oxide.

given , no.of moles of oxygen gas present  in the sample = 21 moles

no.of moles of Fe = 13 moles.

Here, 28 moles of Fe is needed to react with 21 moles of oxygen. Hence, Fe is the limiting reactant.

4 moles of Fe gives 2 moles of iron (III)oxide. Hence, number of moles of the product , formed from 13 moles of Fe is calculated as follows:

(13 moles  ×2 moles)/4moles = 6.5m moles

Therefore, 6.5 moles of iron (III)oxide is formed from 13 moles of Fe.

Answers

Answer:

See explanation

Explanation:

A positron is also called a positive electron. It results from the transformation of a proton into a neutron.

When a nucleus decays by positron emission, the atomic mass of both the parent and daughter nuclei remain the same but the atomic number of the daughter nucleus decreases by 1 compared to that of the parent nucleus. The daughter nucleus is now found one place to the left of the parent nucleus in the periodic table.

This leads to an increase in the Neutron/Proton ratio.

Gaseous butane CH3CH22CH3 will react with gaseous oxygen O2 to produce gaseous carbon dioxide CO2 and gaseous water H2O. Suppose 0.58 g of butane is mixed with 0.874 g of oxygen. Calculate the maximum mass of water that could be produced by the chemical reaction. Round your answer to 3 significant digits.

Answers

Answer:

0.378 g of H₂₂O can be produced.

Explanation:

The combustion reaction is:

2CH₃(CH₂)₂CH₃  +  13O₂  →  8CO₂  +  10H₂O

We convert the mass of reactants to moles:

0.58 g . 1mol / 58.1g = 0.00998 moles of butane

0.874 g . 1mol / 32g = 0.0273 moles of O₂

Oxygen is the limiting reactant. Look at stoichiometry.

2 moles of butane need 13 moles of oxygen to react

Then, 0.00998 moles of gas may react to (0.00998 . 13) / 2 = 0.06487 moles of oyxgen. I only have 0.0273 moles, so i do not have enough oxygen to complete the reaction.

Let's find out the product.

13 moles of oyxgen can produce 10 moles of water.

Then 0.0273 moles of O₂ may produce (0.0273 . 10)/13 =  0.021 moles

We convert to mass  →  0.021 mol . 18g /1mol = 0.378 g

A sample of compound B (also a clear, colorless gas) is analyzed and found to contain 5.19g carbon and 13.84g oxygen. Are these data an example of the law of definite proportions, the law of multiple proportions, or neither? What do these data tell you about substances A and B?

Answers

Answer:

law of multiple proportions

Explanation:

The law of multiple proportions states that, if two elements A and B, combine to form more than one chemical compound. Then the various masses of one element A, which combine separately with a fixed mass of element B are in  simple multiple ratio.

We can see that the ratio of oxygen that combines with carbon in the two compounds( A and B) is 1:2. This demonstrates the law of multiple proportions.

The substances A and B must be CO and CO2 respectively.

For the mechanism, include lone pairs and charges in your answer. Do not draw out any hydrogen explicitly. Do not use abbreviations such as Me or Ph.

Answers

Answer:

See explanation below

Explanation:

In this case we have reaction of addition. In this case a diene reacting with an acid as HBr. This reaction is known as Hydrohalogenation, and, as we have a diene, this kind of reaction can be done as 1,4 addition. Which means that the reaction will be undergoing with an adition in the carbon 1, and carbon 4.

At room temperature we can expect that this reaction can be done in thermodynamic conditions, Now, as the problem states that is forming 4 products, we can expect products of a 1,2 addition too. This product can be formed if the reaction is taking place in the most stable carbocation, and then, by resonance, we can expect the 1,4 product too.

Now, the HBr can be attacked by the double bond of the first position, giving two possible products or by the double bond of the third position giving the other two products. These products are all possible, obviously the most stable will be the major of all of them, but the other three are perfectly possible. One product is formed without doing much, and the other by resonance. Same happens with the other double bond.

In the picture below, you have the mechanism for all the 4 products.

Consider a reaction that connects the ends of a chain of carbons to form a ring. The closure of the ring results in the formation of a new chemical bond, with the bonding electrons going into a bonding sigma molecular orbital at a lower energy. Which of the following statements correctly describes the resulting enthalpy, entropy, and heat changes? Mark all that are correct.
A. The entropy of the surroundings decreases (AS surr < 0) because the closure of the ring results in fewer conformations for the system.
B. The system releases energy to the environment, because its internal energy decreases.
C. The entropy of the surroundings increases (AS surr > 0) because the surroundings absorb heat released by the reaction, and become more disordered.
D. The entropy of the system decreases (AS sys < 0) because the closure of the ring reduces the number of conformations the ring can adopt.
E. The enthalpy or internal energy of the system decreases (AH sys < 0) because the electrons that form the bond enter an orbital that is at a lower energy.

Answers

Answer:

The system releases energy to the environment, because its internal energy decreases.

The entropy of the surroundings increases (AS surr > 0) because the surroundings absorb heat released by the reaction, and become more disordered.

The entropy of the system decreases (AS sys < 0) because the closure of the ring reduces the number of conformations the ring can adopt.

The enthalpy or internal energy of the system decreases (AH sys < 0) because the electrons that form the bond enter an orbital that is at a lower energy.

Explanation:

Now we know that when a reaction is exothermic heat is given off. In this case, we have a reaction that connects the ends of a chain of carbons to form a ring.  The bonding electrons now move into a lower energy bonding sigma molecular orbital.

This leads to a decrease in the entropy and enthalpy of the system because energy is given off, the closure of the ring reduces the number of conformations the ring can adopt and  the electrons that form the bond enter an orbital that is at a lower energy.

The entropy of the surroundings is increased as energy is given out. The surroundings absorb heat released by the reaction, and become more disordered.
