Answer 1

KOH + HCl => KCl + H2O
Fe(OH)2 + 2HCl => FeCl2 + 2H2O
Fe(OH)3 + 3HCl => FeCl3 + 3H2O
Zn(OH)2 + 2HCl => ZnCl2 + 2H2O

Answer 2

Neutralization Reactions with Hydrochloric Acid

To write the balanced chemical equations for the neutralization reactions between the given bases (potassium hydroxide, iron(II) hydroxide, iron(III) hydroxide, copper hydroxide, and zinc hydroxide) and hydrochloric acid, we need to consider the reaction between an acid and a base. In a neutralization reaction, an acid reacts with a base to form a salt and water.

Here are the balanced chemical equations for the neutralization reactions:

1. Potassium Hydroxide (KOH) + Hydrochloric Acid (HCl): - KOH + HCl → KCl + H2O [[1]]

2. Iron(II) Hydroxide (Fe(OH)2) + Hydrochloric Acid (HCl): - Fe(OH)2 + 2HCl → FeCl2 + 2H2O [[2]]

3. Iron(III) Hydroxide (Fe(OH)3) + Hydrochloric Acid (HCl): - Fe(OH)3 + 3HCl → FeCl3 + 3H2O [[3]]

4. Copper Hydroxide (Cu(OH)2) + Hydrochloric Acid (HCl): - Cu(OH)2 + 2HCl → CuCl2 + 2H2O [[4]]

5. Zinc Hydroxide (Zn(OH)2) + Hydrochloric Acid (HCl): - Zn(OH)2 + 2HCl → ZnCl2 + 2H2O [[5]]

Please note that these equations represent the balanced chemical reactions between the given bases and hydrochloric acid.
