How to Balance: Ca + HCl = CaCl2 + H2| Breslyn
Ca + HCl → CaCl 2 + H 2. Word equation: Calcium + Hydrochloric acid → Calcium chloride + Hydrogen gas. Type of Chemical Reaction: For this reaction we have a single displacement reaction. Balancing Strategies: In this reaction Calcium (Ca) metal is reacting with Hydrochloric acid (HCl). the Ca replaces the H in HCl and we end up with CaCl2 and H2.
