How to Balance Calcium + Sulfuric acid → Calcium sulfate + Hydrogen gas

How to Balance: Ca + H2SO4 → CaSO4 + H2

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

Word Equation: Calcium + Sulfuric acid → Calcium sulfate + Hydrogen gas

Balancing Strategies: In this reaction the Ca is displacing the H in the H2SO4 molecule.

To balance the equation be sure to carefully count up all the atoms on each side.

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.
