How to Balance Calcium oxide + Phosphoric acid → Calcium phosphate + Water

How to Balance: CaO + H3PO4 → Ca3(PO4)2 + H2O

Type of Chemical Reaction: This is a double replacement reaction.

Word Equation: Calcium oxide + Phosphoric acid → Calcium phosphate + Water

Balancing Strategies: In this equation it is helpful to consider the PO4 to be one item. That simplifies balancing the equation. It is also helpful to start by balancing the Ca atoms.

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.
