Answer:
Fe(s) + 3H2O2(aq) ................. FeO3(s) + 3H2O (l)
Explanation:
Fe(s) + H2O2(aq) ---------------- FeO3(s) + H2O (l)
To balance the equation put coefficient of 3 at back of H2O and H2O2
Fe(s) + 3H2O2(aq) ................. FeO3(s) + 3H2O (l)
To check, the number of atoms of each element on the left must be equal to that of the right.
Element Left. Right
Fe. 1 1
H. 3×2=6 2×3=6
O. 3×2 =6. 3+3 = 6
This shows that the equation is balanced
