How does the electron structure of atoms change when they form chemical bonds

2. A solution of potassium cyanide, KCN, is made by dissolving 3.2 g of KCN in water. When this solution reacts with excess hydrochloric acid, HCl, it produces 0.30 g of poisonous hydrogen cyanide gas, HCN.

The longer the reaction time is, the the reaction rate is. Reaction time is to reaction rate.
