1. what type of reaction is below?

c(s)+o₂(g)→co₂(g)

Explanation:

1. In double - replacement reactions, two ionic compounds exchange ions to form two new ionic compounds.
2. Single - replacement reactions involve a single element replacing a similar element in a compound.
3. The reaction $C(s)+O_2(g)

ightarrow CO_2(g)$ is a combustion reaction as carbon burns in oxygen to form carbon dioxide.

Answer:

1. B. Double - replacement reactions
2. C. Single - replacement reactions
3. A. Combustion reactions
