Write a balanced equation for the reaction between hydrochloric acid and zinc metal.

Zinc + hydrochloric acid ==> zinc chloride + hydrogen.

These are the reactants and the products. You make it into formulae and balance it. I shall be happy to check your work.

To write a balanced equation for the reaction between hydrochloric acid and zinc metal, we need to follow a step-by-step process:

Step 1: Write the chemical formula for each element or compound involved in the reaction.

Zinc: Zn
Hydrochloric acid: HCl
Zinc chloride: ZnCl2
Hydrogen: H2

Step 2: Write the unbalanced equation using the formulas from step 1.

Zn + HCl → ZnCl2 + H2

Step 3: Balance the equation by adjusting the coefficients in front of each compound to ensure that the number of each element is the same on both sides of the reaction.

Zn + 2HCl → ZnCl2 + H2

After balancing the equation, we have:

Zinc + Hydrochloric acid → Zinc chloride + Hydrogen

Zn + 2HCl → ZnCl2 + H2
