Question

predict the products of the reaction below. that is, complete the right - hand side of the chemical equation. be sure your equation is balanced. hclo₄ + ca(oh)₂ →

Explanation:

Step1: Identify the reaction type

This is an acid - base neutralization reaction. Perchloric acid ($HClO_4$) is an acid and calcium hydroxide ($Ca(OH)_2$) 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 ($Ca^{2 + }$) and the anion from the acid ($ClO_4^{-}$) will form the salt. The formula of the salt is $Ca(ClO_4)_2$.

Step3: Write the unbalanced equation

$HClO_4+Ca(OH)_2
ightarrow Ca(ClO_4)_2 + H_2O$

Step4: Balance the equation

To balance the chlorine and perchlorate ions, we need 2 moles of $HClO_4$. Then, to balance the hydrogen and oxygen atoms, we get 2 moles of $H_2O$. The balanced equation is $2HClO_4+Ca(OH)_2
ightarrow Ca(ClO_4)_2 + 2H_2O$.

Answer:

$2HClO_4+Ca(OH)_2
ightarrow Ca(ClO_4)_2 + 2H_2O$
