Question

1. the equation \\(2\text{kclo}_3 \

ightarrow 2\text{kcl} + 3\text{o}_2\\) is an example of which type of reaction?

a) combustion reaction

b) single-replacement reaction

c) synthesis reaction

d) decomposition reaction

Explanation:

Identify the reactant and products

$$ \text{Reactant: } \text{KClO}_3 \quad (\text{single compound}) $$

$$ \text{Products: } \text{KCl} \text{ and } \text{O}_2 \quad (\text{multiple simpler substances}) $$

Classify the reaction type

$$ \text{General form: } AB ightarrow A + B $$

$$ \text{Reaction type: } \text{Decomposition reaction} $$

Answer:

• A) combustion reaction
• B) single-replacement reaction
• C) synthesis reaction
• D) decomposition reaction (Correct answer)
