Question

classify each chemical reaction: reaction type of reaction (check all that apply) hcl(aq) + naoh(aq) → nacl(aq) + h₂o(l) combination single replacement double replacement decomposition precipitation combustion acid - base mg(clo₃)₂(s) → mgcl₂(s) + 3o₂(g) combination single replacement double replacement decomposition precipitation combustion acid - base naoh(aq) + hbro(aq) → nabro(aq) + h₂o(l) combination single replacement double replacement decomposition precipitation combustion acid - base 2ch₃(ch₂)₂ch₃(g) + 13o₂(g) → 8co₂(g) + 10h₂o(g) combination single replacement double replacement decomposition precipitation combustion acid - base

Explanation:

Step1: Analyze first reaction

The reaction $\mathrm{HCl}(aq)+\mathrm{NaOH}(aq)
ightarrow\mathrm{NaCl}(aq)+\mathrm{H}_{2}\mathrm{O}(l)$ is an acid - base reaction as $\mathrm{HCl}$ (acid) reacts with $\mathrm{NaOH}$ (base) to form salt and water. Also, the ions exchange partners, so it is a double - replacement reaction.

Step2: Analyze second reaction

The reaction $\mathrm{Mg(ClO}_{3})_{2}(s)
ightarrow\mathrm{MgCl}_{2}(s)+3\mathrm{O}_{2}(g)$ is a decomposition reaction since a single compound breaks down into two simpler substances.

Step3: Analyze third reaction

The reaction $\mathrm{NaOH}(aq)+\mathrm{HBrO}(aq)
ightarrow\mathrm{NaBrO}(aq)+\mathrm{H}_{2}\mathrm{O}(l)$ is an acid - base reaction as $\mathrm{HBrO}$ (acid) reacts with $\mathrm{NaOH}$ (base) to form salt and water. It is also a double - replacement reaction.

Step4: Analyze fourth reaction

The reaction $2\mathrm{CH}_{3}(\mathrm{CH}_{2})_{2}\mathrm{CH}_{3}(g)+13\mathrm{O}_{2}(g)
ightarrow8\mathrm{CO}_{2}(g)+10\mathrm{H}_{2}\mathrm{O}(g)$ is a combustion reaction as a hydrocarbon reacts with oxygen to produce carbon dioxide and water.

Answer:

1. double replacement, acid - base
2. decomposition
3. double replacement, acid - base
4. combustion
