Answer:
2H2O2 → O2 + 2H2O
Explanation:
2H2O2
H : 2x2= 4
O : 2x2=4
O2 + 2H2O
H : 2x2=4
O : 2+2=4
First, be sure to count all of H and O atoms on each side of the chemical equation. Once you know how many of each type of atom you have you can only change the coefficients (the numbers in front of atoms or compounds) in order to balance the equation.
