Question
Balance the following equation:
\[\ce{ZnS + O2->ZnO + SO2}\]
Solution
\[\ce{ZnS + O2->ZnO + SO2}\]
Multiply O2 by 3 and to make atoms of oxygen equal on both sides multiply right side by 2.
\[\ce{ZnS + 3O2->2ZnO + 2SO2}\]
Multiply ZnS by 2 to make a balanced equation.
\[\ce{2ZnS + 3O2->2znO + 2SO2}\]
Atoms of every element are equal on both sides.
