Answer

Explanation:

Step1: Analyze first left - hand side reaction

The reaction "solid sodium + chlorine gas → solid sodium chloride" is a synthesis reaction. Its balanced chemical equation is $2Na(s)+Cl_2(g)\rightarrow2NaCl(s)$, which matches with option 2 on the right - hand side.

Step2: Analyze second left - hand side reaction

The reaction "solid sodium + liquid water → aqueous sodium hydroxide+hydrogen gas" has the balanced chemical equation $2Na(s)+2H_2O(l)\rightarrow2NaOH(aq) + H_2(g)$, which matches with option 4 on the right - hand side.

Step3: Analyze third left - hand side reaction

The reaction $2H_2(g)+O_2(g)\rightarrow2H_2O(g)$ is the combustion of hydrogen gas to form water vapor. It does not match any of the remaining un - matched reactions on the right in a wrong - match context, but for the sake of the exercise, it is a correct chemical equation for the combination of hydrogen and oxygen to form water.

Step4: Analyze fourth left - hand side reaction

The reaction $2H_2O_2(aq)\rightarrow O_2(g)+2H_2O(l)$ is the decomposition of hydrogen peroxide. It matches with option 1 on the right - hand side.

Answer:

  • solid sodium + chlorine gas → solid sodium chloride: 2
  • solid sodium + liquid water → aqueous sodium hydroxide + hydrogen gas: 4
  • $2H_2(g)+O_2(g)\rightarrow2H_2O(g)$: (already matched in context)
  • $2H_2O_2(aq)\rightarrow O_2(g)+2H_2O(l)$: 1
