If you had to explain to a friend how to balance a chemical equation, what would you say to them? I attached an image of the game for reference.

just bring the numbers up and down so there are the same numbers of each element on each side.

on this one i would bring the O2 on the left to 1, bring the right side to 2 so there are 2 oxygens on each side, and because the right side now has 4 hydrogens when you brought up the oxygen, bring the number in front of H2 on the left to 2.

the answer should be 2,1,2

it should be all of them because it asks if you included all of those in your answer
