A. Write a balanced chemical equation for this reaction below.
Fe(s) + H2O2(aq) produces FeO3(s) + H2O (l)

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

I hope this was helpful, please mark as brainliest

2h2o2--> 2h2o + o2

this reaction is of the spontaneous decomposition of hydrogen peroxide down into water and oxygen.

add 2 molecules of hydrogen peroxide and 2 molecules of water. since oxygen is naturally diatomic, the total number of atoms of each element is now the same on both sides of the equation so it is balanced.

this may not be entirely correct but let me know.
