Question 5 Predict the reactants of this chemical reaction. That is, fill in the left side of the chemical equation. Be sure the equation you submit is balanced. (You can edit both sides of the equation to balance it, if you need to.) Note: you are writing the molecular, and not the net ionic equation. → + Ca Cl O 4 2 aq H 2 O l Clears your work.

Explanation:

A chemical reaction equation that contains equal number of atoms on both reactant and product side is known as a balanced chemical equation.

For example, when the products are given as [tex]Ca(ClO_{4})_{2}(aq) + H_{2}O(l)[/tex]

So, reactants for this equation will be as follows.

        [tex]HClO_{4}(aq) + Ca(OH)_{2}(aq) \rightarrow Ca(ClO_{4})_{2}(aq) + H_{2}O(l)[/tex]

Number of atoms present on reactant side are as follows.

H = 3

Cl = 1

O = 6

Ca = 1

Number of atoms present on product side are as follows.

H = 2

Cl = 2

O = 9

Ca = 1

Therefore, to balance this equation we multiply [tex]HClO_{4}[/tex] by 2 on reactant side and multiply [tex]H_{2}O[/tex] by 2 on product side.

Hence, the balanced chemical reaction equation will be as follows.

           [tex]2HClO_{4}(aq) + Ca(OH)_{2}(aq) \rightarrow Ca(ClO_{4})_{2}(aq) + 2H_{2}O(l)[/tex]
