When NH3(g) reacts with O2(g), the products of the combustion are NO(g) and H2O(g). What volume of O2(g) is required to react wi

arlik [135]

Answer: The volume of oxygen gas required is 3.75 mL

Explanation:

STP conditions:

1 mole of a gas occupies 22.4 L of volume.

We are given:

Volume of ammonia reacted = 3.00 mL = 0.003 L (Conversion factor: 1 L = 1000 mL)

The chemical equation for the reaction of ammonia with oxygen follows:

$4NH_3(g)+5O_2\rightarrow 4NO(g)+6H_2O(g)$

By Stoichiometry of the reaction:

(4 × 22.4) L of ammonia reacts with (5 × 22.4) L of oxygen gas

So, 0.003 L of ammonia will react with = $\frac{(5\times 22.4)}{(4\times 22.4)}\times 0.003=0.00375L=3.75mL$ of oxygen gas

Hence, the volume of oxygen gas required is 3.75 mL
