Question

Hydrocarbons burn to produce

• A. ${\text{CO}}_2$ and ${\text{H}}_2\text{O}$
• B. ${\text{CO}}_2$ and ${\text{O}}_2$
• C. ${\text{CO}}_2$ and ${\text{H}}_2$
• D. ${\text{CO}}_2$

Answer 1

The correct option is A ${\text{CO}}_2$ and ${\text{H}}_2\text{O}$

As the name suggests, hydrocarbon chains mainly comprised of carbon and hydrogen atoms. When they are burnt in the presence of excess air, they release ${\text{CO}}_2$ and water.

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