How to Balance Nitric acid + Calcium carbonate → Water + Carbon dioxide + Calcium nitrate

How to Balance: HNO3 + CaCO3 → H2O + CO2 + Ca(NO3)2

Type of Chemical Reaction: This is a chemical reaction.

Word Equation: Nitric acid + Calcium carbonate → Water + Carbon dioxide + Calcium nitrate

Balancing Strategies: This chemical equation is a bit challenging to balance because you need to carefully keep track of the O atoms as you work.

After carefully counting the atoms up, start by balancing the N 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.
