How to Balance Sulfur dioxide + Oxygen gas + Water → Sulfuric acid |
How to Balance: SO2 + O2 + H2O → H2SO4
Type of Chemical Reaction: This is a combination (also called synthesis) reaction.
Word Equation: Sulfur dioxide + Oxygen gas + Water → Sulfuric acid
Balancing Strategies: This is an interesting reaction since it produces H2SO4, sulfuric acid. Be sure to count all of the Oxygen (O) atoms on the reactant side when balancing the equation. For a complete explanation, watch:
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).
