Problem

Imagine you mix 16.05 g of methane (CH4) gas and 96.00 g of oxygen (O2) gas and then ignite the mixture. After a bright flash and a loud bang, some water droplets form on the inside of the reaction vessel.

Write the balanced chemical reaction for the combustion of methane.

Solution

We know that combustion of a hydrocarbon (made up hydrogen and carbons) like methane will produce carbon dioxide (CO2) and water (H2O) as the products. The water formed is what explains the droplets found on the sides of the vessel but take note that it is initially a gas after the combustion reaction and just, later on, condenses into a liquid to form the droplets.
