choose the products that complete the reaction. the chemical equation may not be balanced.\nhc₂h₃o₂ +…

Explanation:

Step1: Identify Reaction Type

The reaction is between an acid ($\ce{HC2H3O2}$, acetic acid) and a base ($\ce{Ca(OH)2}$, calcium hydroxide), so it's a neutralization reaction. Neutralization reactions produce a salt and water.

Step2: Analyze Products

• For the first option: $\ce{Ca(C2H3O2)2}$ is the salt (calcium acetate) and $\ce{H2O}$ is water, which fits neutralization.
• The second option includes $\ce{CO2}$, which is produced in acid - carbonate reactions, not acid - base (hydroxide) neutralization.
• The third option includes $\ce{H2}$, which is not a product of acid - base neutralization (no redox here to produce $\ce{H2}$).

Answer:

$\ce{Ca(C2H3O2)2 + H2O}$ (the first option: $\ce{Ca(C2H3O2)2 + H2O}$)
