Balancing Chemical Equations

Balancing chemical equations involves adjusting the coefficients of the chemical formulas to ensure that the same number of each type of atom is present on both sides of the equation.

The given chemical equations are: 1. S + O2 = SO2 2. Fe + S = FeS

To balance these equations, we need to adjust the coefficients of the chemical formulas to ensure that the number of each type of atom is the same on both sides of the equation.

Balancing the Equation S + O2 = SO2

To balance the equation S + O2 = SO2, we can follow these steps:

1. Balance the non-hydrogen and non-oxygen atoms first. In this case, we have sulfur (S) and oxygen (O). 2. Start by balancing the sulfur atoms on both sides of the equation. We have 1 sulfur atom on the left and 1 sulfur atom on the right, so sulfur is already balanced. 3. Next, balance the oxygen atoms. There are 2 oxygen atoms in the O2 molecule on the left and 2 oxygen atoms in the SO2 molecule on the right, so oxygen is also balanced.

Therefore, the balanced equation is: S + O2 = SO2

Balancing the Equation Fe + S = FeS

To balance the equation Fe + S = FeS, we can follow these steps:

1. Balance the non-hydrogen and non-oxygen atoms first. In this case, we have iron (Fe) and sulfur (S). 2. Start by balancing the iron atoms on both sides of the equation. We have 1 iron atom on the left and 1 iron atom on the right, so iron is already balanced. 3. Next, balance the sulfur atoms. There is 1 sulfur atom on the left and 1 sulfur atom on the right, so sulfur is also balanced.

Therefore, the balanced equation is: Fe + S = FeS

In both cases, the coefficients for each compound remain as 1, as the equations are already balanced.
