When 2 moles of ammonia (NH3) decomposes into nitrogen gas (N2) and hydrogen gas (H2), how many moles of HYDROGEN gas are produced?
-1 mole
-2 moles
-3 moles
-4 moles
Look at the equation. The coefficients are the secret.
2NH3 ==> N2 + 3H2
The equation TELLS you that 2 mols NH3 produces 3 moles H2.
Where is this 3H2 coming from?
So I’m thinking that there are 3 moles of hydrogen gas from 2 miles of ammonia?
Oh I see. The (NH3)? Therefore ammonia produces one molecule of nitrogen and three molecules of hydrogen?
To determine the number of moles of hydrogen gas produced when 2 moles of ammonia decompose, we need to examine the balanced chemical equation for the reaction:
2 NH3 → N2 + 3 H2
From the equation, we can see that for every 2 moles of ammonia (NH3), we get 3 moles of hydrogen gas (H2). Therefore, the correct answer is:
- 3 moles
