After balancing the equation, the coefficient for HS1U1P1+S1S1P0 is found to be 14. This is because there are 14 sulfur atoms on the left side (in CrS1U1B12S1U1B0OS1U1B17S1U1B0S1U1P12- S1S1P0(aq)) and only 1 on the right side (in ZnS1U1P12). Therefore, we need a coefficient of 14 to balance the sulfur atoms on both sides.
