predict the products of the reaction below. that is, complete the right - hand side of the chemical…

Explanation:

Step1: Identify the reaction type

This is an acid - base neutralization reaction. HI is an acid and Ba(OH)$_2$ is a base. The products of an acid - base neutralization reaction are a salt and water.

Step2: Determine the salt

The cation from the base (Ba$^{2 + }$) and the anion from the acid (I$^-$) will form the salt. The salt is BaI$_{2}$.

Step3: Determine the water

The H$^+$ from the acid and OH$^-$ from the base combine to form H$_{2}$O.

Step4: Balance the equation

We need 2 moles of HI to react with 1 mole of Ba(OH)${2}$ to balance the hydrogen and iodine atoms. The balanced equation is $2HI+Ba(OH){2}\rightarrow BaI_{2} + 2H_{2}O$.

Answer:

$2HI+Ba(OH){2}\rightarrow BaI{2} + 2H_{2}O$
