Question

Identify the type of reaction represented by each equation.

A: H2 + Cl2 → 2HCl
B: CH4 + 2O2 → CO2 + 2H2O

Answer 1

Step-by-step explanation:

When two elements combine together and result in the formation of a single product then it is known as a synthesis reaction.

For example,
`H_(2) + Cl_(2) \rightarrow 2HCl`

Therefore, the given reaction
`H_(2) + Cl_(2) \rightarrow 2HCl` is a synthesis reaction.

Combustion is defined as the reaction in which a hydrocarbon reacts with oxygen and leads to the formation of carbon dioxide and water.

For example,
`CH_(4) + 2O_(2) \rightarrow CO_(2) + H_(2)O`

Hence, the given reaction
`CH_(4) + 2O_(2) \rightarrow CO_(2) + H_(2)O` is a combustion reaction.
