If 10.0 L of nitrogen gas reacts with 16.0 L of hydrogen gas, how many liters of ammonia gas (NH3) will be
produced?

Answers

Volume of ammonia gas : 10.67 L

Further explanation

Given

10.0 L of nitrogen gas

16.0 L of hydrogen gas

Required

Volume of ammonia gas

Solution

Reaction

N₂ + 3H₂ ⇒ 2NH₃

From Avogadro's hypothesis, at the same temperature and pressure, the ratio of gas volume will be equal to the ratio of gas moles  

Find limiting reactant :

N₂ : 10 : 1 = 10

H₂ : 16 : 3 = 5.3

H₂ as a limiting reactant

So volume of NH₃ based on H₂

= 2/3 x volume H₂

= 2/3 x 16 L

= 10.67 L

If I have 5 mols of Neon how many grams of Neon do I have?

Answers

Answer:

20.1797 grams.

Explanation:

The molecular formula for Neon is Ne. The SI base unit for amount of substance is the mole. 1 mole is equal to 1 moles Neon, or 20.1797 grams.

Using the balanced chemical equation:
4NH3 + 302 --> 2N2 + 6H20
Determine the amount of grams of N2 is produced If 4.03 moles of NH3 react?

Answers

Your answer and workings are all mentioned in the picture below.

Taking into account the reaction stoichiometry, 56.42 grams of N₂ are formed when 4 moles of NH₃ react.

Reaction stoichiometry

In first place, the balanced reaction is:

4 NH₃ + 3 O₂  → 2 N₂+ 6 H₂O

By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of moles of each compound participate in the reaction:

NH₃: 4 molesO₂: 3 molesN₂: 2 molesH₂O: 6 moles

The molar mass of the compounds is:

NH₃: 17 g/moleO₂: 32 g/moleN₂: 28 g/moleH₂O: 18 g/mole

Then, by reaction stoichiometry, the following mass quantities of each compound participate in the reaction:

NH₃: 4 moles ×17 g/mole= 68 gramsO₂: 3 moles ×32 g/mole= 96 gramsN₂: 2 moles ×28 g/mole= 56 gramsH₂O: 6 moles ×18 g/mole= 108 grams

Mass of N₂ formed

The following rule of three can be applied: if by reaction stoichiometry 4 moles of NH₃ form 56 grams of N₂, 4.03 moles of NH₃ form how much mass of N₂?

[tex]mass of N_{2} =\frac{4.03 moles NH_{3} x56 grams of N_{2} }{4 moles NH_{3}}[/tex]

mass of N₂= 56.42 grams

Then, 56.42 grams of N₂ are formed when 4 moles of NH₃ react.

A mole of Br2 and a mole of CH2Br2
Select one:

A. have a mass of 1g each

B. contain the same number of molecules

C. contain one molecule each

D. have the same mass

Answers

The answer is A it should be anyway

The term mole is defined as the amount of substance of a system which contains as many elementary entities. A mole of Br₂ and a mole of CH₂Br₂ have a mass of 1g each. Therefore, option A is correct.

What do you mean by mole ?

The term mole is defined as the amount of substance of a system which contains as many elementary entities.

1 mole is equal to 6.023 × 10 ²³ molecules.

One mole of any substance is equal to 6.023 × 10²³ units of that substance such as atoms, molecules, or ions. The number 6.023 × 10²³ is called as Avogadro's number or Avogadro's constant.

The mole concept can be used to convert between mass and number of particles.

A mole of Br₂ and a mole of CH₂Br₂ have a mass of 1g each. Because one mole of substance is equal to 6.023 × 10 ²³ molecules.

Thus, option A is correct.

Find the mass of 5.60 L O2 at 1.75 atm and 250.0 K

Answers

Answer:

Moles O2 = pV/RT = 2.75 x 5.60 / 0.08206 x 250=0.751

mass = 32 g/mol x 0.751 mol= 24.0 g

Explanation:

Hope it help

Mark me as brainliest

The mass of 5.60 Liter oxygen at 1.75 atm pressure and 250.0 K temperature is 24.0 gram.

What is ideal gas equation?

Ideal gas equation is a hypothesis which tells about the behavior of gas at standard condition and it is represented as:

PV = nRT, where

P = pressure = 1.75 atm

V = volume = 5.60 L

R = universal gas constant = 0.0821 L.atm /K.mol

T = temperature = 250 K

n is the moles of gas which will further define as:

n = W/M, where

W = required mass

M = molar mass

Now putting all the value in the above ideal gas equation and calculate for moles as:

n = (1.75)(5.60) / (0.0821)(250)

n = 0.751

Molar mass of oxygen is 32 g/mol and we calculate their required mass as:
W = 32 g/mol x 0.751 mol= 24.0 g

Hence, the required mass of oxygen is 24.0 g.

Answers

Answer:

Heating of the liquid water in a microwave.

Explanation:

Radiation is a form of heat transfer process that does not require a material medium rather it travels through space or vacuum in the form of electromagnetic waves or radiation. Heat transfer by radiation occurs in the form of microwaves, infrared radiation, visible light, or another form of electromagnetic radiation is emitted or absorbed.  Some common examples of heat transfer by radiation is the warming of the Earth by the Sun, the warmth one experiences while sitting by the campfire, or the heating up of foods in a microwave.

Black bodies or surfaces are good absorbers as well as emitters of radiation. On the other shiny or white surfaces are poor radiators of heat.

From the above discussion on radiation, it can be seen that when the chemist takes the liquid and heats it in a microwave, the heat absorbed by the liquid to change to gaseous state is transferred through radiation.
