Write a balanced chemical equation for each of the following:

(i) Producing ethane from bromoethane using Zn/Cu couple in alcohol.

(ii) Complete combustion of ethane

(i) Ethane from bromoethane using Zn/Cu couple in alcohol

$\underset{\text{bromoethane}}{\text{C}$2\text{H}5\text{Br}} + \underset{\text{nascent hydrogen}}{2\text{[H]}} \xrightarrow[\text{alcohol}]{\text{Zn/Cu couple}} \underset{\text{ethane}}{\text{C}2\text{H}6} +\text{HBr}

(ii) Complete combustion of ethane

$2\text{C}$2\text{H}6 + 7\text{O}2 \longrightarrow 4\text{CO}2 + 6\text{H}_2\text{O} + \Delta
