How to Balance Calcium oxide + Nitric acid → Calcium nitrate + water |
How to Balance: CaO + HNO3 → Ca(NO3)2 + H2O
Type of Chemical Reaction: This is a double replacement reaction.
Word Equation: Calcium oxide + Nitric acid → Calcium nitrate + water
Balancing Strategies: To balance this equation it is helpful to consider the nitrate ion (NO3) to be one item. That is because it appears on both sides of the equation. This makes the balancing much, much simpler.

About Balancing Chemical EquationsWhen 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).
Never change the subscripts (the small numbers after elements).
