To balance the chemical equation , we need to ensure that the number of atoms of each element is the same on both sides of the equation.Let's start by writing down the number of atoms of each element in the unbalanced equation: On the left side:- Fe: 1- S: 2- O: 2On the right side:- Fe: 2- S: 1- O: 5To balance the equation, we need to adjust the coefficients in front of each compound.Let's start with the iron (Fe) atoms. We have 1 Fe atom on the left side and 2 Fe atoms on the right side. To balance the Fe atoms, we need to put a coefficient of 2 in front of : Now let's move on to the sulfur (S) atoms. We have 2 S atoms on the left side and 1 S atom on the right side. To balance the S atoms, we need to put a coefficient of 2 in front of : Finally, let's balance the oxygen (O) atoms. We have 2 O atoms on the left side and 7 O atoms on the right side (3 from and 4 from ). To balance the O atoms, we need to put a coefficient of 4 in front of : Now the equation is balanced, and we can see that the coefficients are:- : 2- : 4- : 1- : 2Therefore, the correct answer is .
