The key point in balancing equations is that the number of atoms of each element must be the same on either side.
_BaO2-> BaO+ _O2
right side has 3 oxygen and one barium now, but on the left, only 2 oxygen and one Ba
so we will try multiplying the left with 2.
2BaO2-> BaO+ _O2
to balance the number of Ba on the right, multiply it also with 2
2BaO2-> 2BaO+ _O2
Now count the number of atoms,
4 oxygens and 2 barium on the left and the same number on the right.
So the balanced equation is 2BaO2-> 2BaO+ O2
Coefficient of BaO2 is 2 -- ans© BrainMass Inc. brainmass.com December 24, 2021, 5:35 pm ad1c9bdddf>
