Explanation:
1. When zinc reacts with hydrochloric acid it produces zinc chloride and hydrogen gas.
We can measure the rate of the reaction by measuring how fast the reaction produces hydrogen. This requires a conical flask and gas syringe.
Zn + HCl → ZnCl2 + H2
2.Hydrochloric acid reacts with sodium hydroxide to form sodium chloride (the salt) and water. Sodium chloride is made up of Na+ cations from the base (NaOH) and Cl- anions from the acid (HCl).
3. Ca(OH)2 + H2SO4 → CaSO4 + H2O. Word equation: Calcium hydroxide + Sulfuric acid → Calcium sulfate + Water. Type of Chemical Reaction: For this reaction we have a neutralization reaction. Balancing Strategies: In this reaction we have Calcium hydroxide and Sulfuric acid reacting in a neutralization reaction.
