How to Balance Dinitrogen pentoxide + Water → Nitric Acid

How to Balance: N2O5 + H2O → HNO3

Type of Chemical Reaction: This is a combination reaction.

Word Equation: Dinitrogen pentoxide + Water → Nitric Acid

Balancing Strategies: For this combination reaction we have N2O5 and H2O combining to form HNO3 (Nitric acid).

Be sure to count all of the oxygen atoms on the reactant side of the equation or balancing will be very difficult!

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.
