How to Balance Calcium + Hydrochloric acid → Calcium chloride + Hydrogen gas

How to Balance: Ca + HCl → CaCl2 + H2

Type of Chemical Reaction: This is a single displacement reaction.

Word Equation: Calcium + Hydrochloric acid → Calcium chloride + Hydrogen gas

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.

Overall it is a fairly straightforward equation to balance.

About Balancing Chemical Equations

When balancing chemical equations our goal is to have the same number of each type of atom on both sides of the equation.

Only change the coefficients (these are the numbers in front substances).
Coefficients are the numbers in front of the molecule.
Never change the subscripts (the small numbers after elements).
Coefficients are the numbers in front of the molecule.
