Question

1. discuss why the reaction between zinc and hydrochloric acid is not considered a combination reaction. you should write a word equation and a balanced symbol equation in your answer.

Explanation:

A combination reaction has the general form \(A + B
ightarrow AB\) (two or more reactants combine to form one product). For the reaction between zinc (\(Zn\)) and hydrochloric acid (\(HCl\)):

• Word equation: Zinc + Hydrochloric acid → Zinc chloride + Hydrogen.
• Symbol equation: \(Zn+2HCl = ZnCl_{2}+H_{2}\uparrow\).

Here, there are two products (\(ZnCl_{2}\) and \(H_{2}\)), while a combination reaction has only one product. So it does not fit the definition of a combination reaction.

Answer:

The reaction of zinc and hydrochloric acid is not a combination reaction because it has two products (\(ZnCl_{2}\) and \(H_{2}\)), while a combination reaction has only one product. Word equation: Zinc + Hydrochloric acid → Zinc chloride + Hydrogen. Balanced symbol equation: \(Zn + 2HCl=ZnCl_{2}+H_{2}\uparrow\).
