Question

3. Ammonia, NH3, is a typical ingredient in household cleaners. It is produced through a combination reaction involving N2(g) and H2(g). If 24.0 mol of H2(g) react with excess N2(g), how many moles of ammonia are produced?

Answer 1

16 moles of Ammonia are produced

Step-by-step explanation:

First thing's first, we have to write out the balanced chemical equation for the production of ammonia.

We know that;

Nitrogen + Hydrogen --> Ammonia

N2 + 3H2 --> 2NH3

From the equation, we can tell that 1 mol of N2 reacts with 3 mol of H2 to produce 2 mol of NH3.

Since N2 is in excess, it cannot be a limiting reactant. So the mole relationship is reduced to;

3 mol of H2 produces 2 mol of NH3

24 mol of H2 produces x mol of NH3

3 = 2

24 = x

Upon cross multiplication and solving for x;

x = ( 24 * 2) / 3

x = 16 mol

Answer 2

N2 + 3H2 ----> 2NH3

you can see 3 moles H2 reacts to form 2 moles NH3
Therefore moles NH3 = 2 / 3 x moles H2
= 2/3 x 12.0 mol
= 8.00 mol NH3 hope this help
