Question:

Ethane combusts in air to form carbon dioxide and water:

2C2H6+7O2 4CO2+6H2O

This process requires how many moles of O2 for every 2.10 mol of C2H6 that reacts?

Combustion Reactions:

Alkanes are hydrocarbons with a general formula of {eq}\rm C_nH_{2n+2}{/eq} which can undergo combustion reactions in the presence of oxygen gas. A complete combustion reaction occurs when {eq}\rm CO_2{/eq} and {eq}\rm H_2O{/eq} are formed as products of the combustion reaction. The general chemical equation for a combustion reaction is given below.

{eq}\rm C_xH_y~+~O_2~\to~CO_2~+~H_2O {/eq}
