When 2 moles of ammonia (NH3) decomposes into nitrogen gas (N2) and hydrogen gas (H2), how many moles of nitrogen gas are produced?
1 mole
2 moles
3 moles
4 moles
If the reaction is 2NH3 → N2 + 3H2
then you will get 3 moles
To find out how many moles of nitrogen gas (N2) are produced when 2 moles of ammonia (NH3) decomposes, we need to refer to the balanced chemical equation for the reaction.
The balanced chemical equation for the decomposition of ammonia can be written as follows:
2 NH3 → N2 + 3 H2
From the balanced equation, we can see that for every 2 moles of ammonia that decompose, 1 mole of nitrogen gas is produced. Therefore, the correct answer is 1 mole.
To determine the number of moles of nitrogen gas produced when 2 moles of ammonia decomposes, we need to examine the balanced equation for the reaction.
The balanced equation for the decomposition of ammonia is:
2 NH3 → N2 + 3 H2
According to this equation, 2 moles of ammonia yield 1 mole of nitrogen gas. Therefore, the correct answer is:
1 mole of nitrogen gas.
