Question 47

Methane, $CH4\text{CH}_4$ , reacts with oxygen, $O2\text{O}_2$ , to form carbon dioxide, $CO2\text{CO}_2$ , and water, $H2O\text{H}_2\text{O}$ .

The balanced symbol equation is shown:

\text{CH}_4(\text{g}) + 2\text{O}_2(\text{g}) \rightarrow \text{CO}_2(\text{g}) + 2\text{H}_2\text{O}(\text{l})

Calculate the mass of carbon dioxide made from $g80.0\text{ g}$ of methane.

(The relative atomic mass, $A_r$ , of $H\text{H}$ is $1.0$ , of $C\text{C}$ is $12.0$ and of $O\text{O}$ is $16.0$ ).
