Question

1. what are the reactants in the following chemical reaction?

$\ce{ch_{4} + 2o_{2} -> co_{2} + 2h_{2}o}$
$\ce{ch_{4}}$ and $\ce{2h_{2}o}$
$\ce{ch_{4}}$ and $\ce{2o_{2}}$
$\ce{co_{2}}$ and $\ce{2h_{2}o}$
$\ce{co_{2}}$ and $\ce{2o_{2}}$

Explanation:

In a chemical reaction, reactants are the substances present on the left side of the arrow ($
ightarrow$), which undergo a chemical change to form products (right side of the arrow). For the reaction $\text{CH}_4 + 2\text{O}_2
ightarrow \text{CO}_2 + 2\text{H}_2\text{O}$, the left-side substances are $\text{CH}_4$ and $2\text{O}_2$, so these are the reactants.

Answer:

B. $\text{CH}_4$ and $2\text{O}_2$
