pickupchik [31]

Answer:

2 HClO₃ + Ca(OH)₂ ---> Ca(ClO₃)₂ + 2 H₂O

Explanation:

This is a double-displacement reaction. In these reactions, the cation of one molecule swaps with the cation of another.

In this case, the hydrogen cation (H⁺) from HClO₃ swaps with the calcium cation (Ca²⁺) of Ca(OH)₂. When writing the products, keep the charges of the ions in mind. The products must be neutral, so some will need to have more than 1 cation/anion.

The unbalanced equation:

HClO₃ + Ca(OH)₂ ---> Ca(ClO₃)₂ + H₂O

<u>Reactants</u>: 3 hydrogen, 1 chlorine, 5 oxygen, 1 calcium

<u>Products</u>: 2 hydrogen, 2 chlorine, 7 oxygen, 1 calcium

The balanced equation:

2 HClO₃ + Ca(OH)₂ ---> Ca(ClO₃)₂ + 2 H₂O

<u>Reactants</u>: 4 hydrogen, 2 chlorine, 8 oxygen, 1 calcium

<u>Products</u>: 4 hydrogen, 2 chlorine, 8 oxygen, 1 calcium
