Question

Ammonia gas is formed by the combination of nitrogen and hydrogen.
$N_2+3H_2\to 2N{H}_3$
In the above equation :

• A. nitrogen and hydrogen are reactants
• B. one molecule of nitrogen combine with 3 molecule of hydrogen and forms two molecule of ammonia
• C. one volume of nitrogen and three volume of hydrogen combine and give 2 volume of ammonia gas
• D. reactants and products are not gases

Answer 1

Answer: (A), (B), (C)

The correct options are
A nitrogen and hydrogen are reactants
B one molecule of nitrogen combine with 3 molecule of hydrogen and forms two molecule of ammonia
C one volume of nitrogen and three volume of hydrogen combine and give 2 volume of ammonia gas

As we can see from the reaction equation, 1 mole of nitrogen is reacting with 3 moles of hydrogen to give 2 moles of ammonia gas.

Volume is directly proportional to the number of mole.
