choose the products that complete the reaction. the chemical equation may not be balanced. hc₂h₃o₂ + ca(oh)₂…

Explanation:

Step1: Identify reaction type

This is an acid - base neutralization reaction. Acetic acid ($HC_2H_3O_2$) reacts with calcium hydroxide ($Ca(OH)_2$).

Step2: Determine products

In an acid - base neutralization, the products are a salt and water. The salt is formed by the combination of the cation from the base ($Ca^{2 + }$) and the anion from the acid ($C_2H_3O_2^{-}$), and water is formed from the combination of $H^+$ from the acid and $OH^-$ from the base. The reaction is $2HC_2H_3O_2+Ca(OH)_2\rightarrow Ca(C_2H_3O_2)_2 + 2H_2O$.

Answer:

$Ca(C_2H_3O_2)_2 + H_2O$ (the first option)
