Question

# The balance equation for the complete combustion of ethane is:A. $2{{C}_{2}}{{H}_{6}}+5{{O}_{2}}\to 4C{{O}_{2}}+2{{H}_{2}}O+Heat$B. $2{{C}_{2}}{{H}_{6}}+7{{O}_{2}}\to 4C{{O}_{2}}+6{{H}_{2}}O+Heat$C. ${{C}_{2}}{{H}_{6}}+7{{O}_{2}}\to 2C{{O}_{2}}+3{{H}_{2}}O+Heat$D. ${{C}_{2}}{{H}_{6}}+5{{O}_{2}}\to 2C{{O}_{2}}+3{{H}_{2}}O+Heat$

Hint: Ethane is an alkane represented by the chemical formula ${{C}_{2}}{{H}_{6}}$. It is kept in the category of hydrocarbons as it is one of the hydrocarbon components of natural gas which is generally a fossil fuel. Purest form of ethane is colorless and odorless in nature.
$2{{C}_{2}}{{H}_{6}}+7{{O}_{2}}\to 4C{{O}_{2}}+6{{H}_{2}}O+Heat$
