A2.50-l sample of a colorless gas at stp decomposed to give 2.50 l of n2 and 1.25 l of o2 at stp. what is the colorless gas?

Answer;

N2O (Nitrogen (i) oxide.

Explanation;

The decomposition would be; 2N2O(g) = 2N2 (g)+ O2 (g)

Which means the ratio of; N2O :N2 :O2 = 2:2:1

The volume of colorless gas is 2.5 liters, N2 is 2.5 liters and oxygen is 1.25 liters; which also gives us a ratio of; 2: 2: 1.

Alternatively; here is twice as much N2 as O2. therefore; the formula would be N2O (nitrogen dioxide) to make 1 volume of N2 for every 2 volumes of O2.
