Write down the molecular and ionic equations between: A) magnesium and hydrochloric acid

Write down the molecular and ionic equations between: A) magnesium and hydrochloric acid B) potassium nitrate and sulfuric acid

A) Reaction between magnesium and hydrochloric acid. As a result of the reaction, magnesium chloride is formed and hydrogen is released. The chemical equation for the reaction is as follows:

Mg + 2 HCl = MgCl2 + H2
The ionic reaction equation is as follows:

Mg 2+ + H + + 2 Cl- = Mg 2+ + 2 Cl- + H2 +

B) Potassium nitrate react with sulfuric acid. The reaction produces potassium sulfate and nitric acid. The chemical equation for the reaction is as follows:

KNO3 + H2SO4 = KHSO4 + HNO3

The ionic reaction equation is as follows:

2 K + +2 NO3 – = 2 K + + SO4 2- + 2 H + + 2 NO3-.
