Answer:

Zn + 2 HCl → ZnCl₂ + H₂

Explanation:

We have to complete this single replacement reaction.

Zn(s) + HCl(aq) →

We need to decide if Zn will replace H⁺ or Cl⁻. Zn can form the cation Zn²⁺ but it does not have a negative oxidation number to form an anion. As a consequence, the cation Zn²⁺ will replace the cation H⁺ to form ZnCl₂. H₂ will be released as a gas.

Zn(s) + 2 HCl(aq) → ZnCl₂(aq) + H₂(g)

Convection brings the cold water to the hot surface of the hot sauce pan. Once when there is only hot water in the sauce pan, the water will boil.
