Question 8

A mixture of methane and oxygen in a gas syringe is ignited and the methane burns completely. The equation is:

$CH4+2O2→CO2+2H2O\text{CH}_4 + 2\text{O}_2 \rightarrow \text{CO}_2 + 2\text{H}_2\text{O}$

The gas syringe contains 60 cm³ of methane and 150 cm³ of oxygen. The carbon dioxide is gaseous and the water is liquid at the conditions used. All gas volumes are measured at the same temperature and pressure.

By how much does the total gas volume decrease?
