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

Please explain how you got the answer

as in your other post, If the reaction is 2NH3 → N2 + 3H2

then you will get 3 moles. Just look at the equation.

Oh no, I must have done the wrong one. Wasn’t meant to be two of the same

To determine how many moles of nitrogen gas are produced when 2 moles of ammonia decomposes into nitrogen gas and hydrogen gas, we need to set up a balanced chemical equation first.

The balanced equation for the decomposition of ammonia (NH3) is:
2 NH3 -> N2 + 3 H2

From the balanced equation, we can see that two moles of ammonia (NH3) produce one mole of nitrogen gas (N2). Therefore, the answer is 1 mole of nitrogen gas.

So, the correct answer is:
1 mole
