Question

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.

Answer 1

A chemical equation represents a chemical reaction, with reactants on the left and products on the right of the arrow.

Step-by-step explanation:

A chemical equation represents a chemical reaction. The reactants are the substances that are consumed in the reaction, while the products are the substances that are formed. The reactants are written on the left side of the equation, separated by a plus sign (+), followed by an arrow (→), and the products are written on the right side of the arrow.

For example, if we consider the combustion of methane, the chemical equation would be:

CH4 + 2O2 → CO2 + 2H2O

Answer 2

Hydrogen chloride (HCl) and Calcium hydroxide (CaOH). (see balanced equation below)

Step-by-step explanation:

In a neutralization reaction as is the case of the question (see attachment), an acid would be neutralized by a base to form salt and water.

The most plausible reactants for the reaction given the number of moles of the product, is therefore Hydrogen chloride (HCl) and Calcium hydroxide (Ca(OH)2).

`HCl _((aq)) + Ca(OH)_(2) _((aq))` →
`CaCl_(2)_((s)) + H_(2) O_((l))`
