A mixture of 50.0 mL of ammonia gas and 60.0 mL of oxygen gas react. If all the gases are at the same temperature and pressure,

Answer:

72.0 mL of steam is formed.

Explanation:

The reaction is :

$4 NH_{3} + 5O_{2} \rightarrow 4NO+6H_{2} O$

You can treat coefficient of compounds as amount of volume used.

Therefore for 4 mL of ammonia 5 mL of oxygen is used to form 4 mL of nitric oxide gas and 6 mL of steam.

For 1 mL of ammonia $\frac{5}{4}$ (=1.25) mL of oxygen is used to form $\frac{4}{4}$ (=1) mL of nitric oxide gas and $\frac{6}{4}$ (=1.5) mL of steam.

Just transform the chemical equation by dividing the whole equation by 4 so that the coefficient of $NH_{3}$ become one like this

$NH_{3} + \frac{5}{4} O_{2} \rightarrow \frac{4}{4}NO+\frac{6}{4}H_{2} O$

We don't know which one will be completely exhausted and which one will be left so we have to consider two cases :

1. Assume ammonia to be completely exhausted

For 50 mL of ammonia $50 \times \frac{5}{4}$ (= 62.5) mL of oxygen is needed. But we have just 60 mL of oxygen so this assumption is false.

2. Assume oxygen to be completely exhausted

For 60 mL of oxygen only $60 \times \frac{4}{5}$ (=48) mL of ammonia is needed. In this case we have sufficient amount of ammonia. So this case is true.

$60\times\frac{4}{5}NH_{3} + 60\ O_{2} \rightarrow 60\times\frac{4}{5}NO+60\times\frac{6}{5}H_{2} O\\\\48NH_{3} + 60\ O_{2} \rightarrow 48NO+72H_{2} O$

Now we know that during complete reaction 48 mL of ammonia and 60 mL of oxygen is used which will form $60 \times \frac{4}{5}$ (= 48) mL of nitic oxide gas and $60 \times \frac{6}{5}$ (= 72) mL of steam.
