Question

After the equation below has been balanced for a reaction in an acidic solution, what will the coefficients of the reactants and products be, in order? h2o2 + feso4 + h2so4 fe2(so4)3 + h2o

Answer 1

First, we have to start balancing the equation:

H2O2 + FeSO4 + H2SO4 → Fe2(SO4)3 + H2O

we can see that the number of H atoms on the left side is 4 and on the right side is  2 so we have to make the number of H atoms are equal on both sides

so, we will put 2H2O instead of H2O

H2O2 + FeSO4 + H2SO4 → Fe2(SO4)3 + 2H2O

we can see that number of O on the left side is 10 and on the right side 14

so we will put 2 FeSO4 instead of FeSO4

H2O2 + 2FeSO4 + H2SO4 → →Fe2(SO4)3 + 2H2O

∴ the coefficients of the reactants and products will be in order 1 2 1 1 2
