Question
Balance the following equation:
\[\ce{C + H2SO4->CO2 + H2O + SO2}\]
Advertisements
Solution
\[\ce{C + H2SO4->CO2 + H2O + SO2}\]
Atoms of oxygen are not equal on both sides.
To make atoms equal, we multiply H2SO4 on left by 2 and equate.
\[\ce{C + 2H2SO4->CO2 + 2H2O + 2SO2}\]
Atoms of each element are equal on both sides.
