This is a classic chemical equation used to demonstrate balancing. Visit https://www.Breslyn.org for video guides on balancing equations and more!
In order to balance H2 + O2 → H2O you'll need to make sure the number of H and O atoms are the same on both sides of the chemical equation. You do that by changing the coefficients (the numbers in front of atoms or compounds).
First, be sure to count all of the 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.
