Answer:

Well then...

Explanation:

to balance the equation

H2 + O2 -> H2O

we see there is too little oxygens on the right side

so put 2 after H20

H2 + O2 -> 2H2O

now the oxygens are balanced but there are too little hydrogens on the left side so put

a 2

2H2 + O2 -> 2H2O

This is now balanced!
