1. what kind of reaction is represented by the equation?

\\(\text{ch}_4 + 2\text{o}_2 \
ightarrow \text{co}_2 + 2\text{h}_2\text{o}\\)

a) synthesis

b) double replacement

c) single replacement

d) combustion

Explanation:

Identify the reactants and products

$$ \text{Reactants: } \text{CH}_4 \text{ (hydrocarbon)} + \text{O}_2 \text{ (oxygen)} $$

$$ \text{Products: } \text{CO}_2 \text{ (carbon dioxide)} + \text{H}_2\text{O} \text{ (water)} $$

Classify the reaction type

$$ \text{Hydrocarbon} + \text{O}_2 ightarrow \text{CO}_2 + \text{H}_2\text{O} \implies \text{Combustion reaction} $$

Match with the given options

$$ \text{Option D corresponds to combustion.} $$

Answer:

• A) synthesis
• B) double replacement
• C) single replacement
• D) combustion (Correct answer)
