Question

match the following chemical as either a reactant or a product: mg + hcl → mgcl₂ + h₂

Explanation:

Step1: Analyze the chemical equation

In the chemical equation \(Mg + HCl
ightarrow MgCl_{2}+H_{2}\), reactants are on the left - hand side and products are on the right - hand side.

Step2: Classify each substance

• \(Mg\) (magnesium) and \(HCl\) (hydrochloric acid) are on the left - hand side of the equation, so they are reactants.
• \(MgCl_{2}\) (magnesium chloride) and \(H_{2}\) (hydrogen gas) are on the right - hand side of the equation, so they are products.

Answer:

Reactant: \(Mg\), \(HCl\); Product: \(MgCl_{2}\), \(H_{2}\)
