Now, there are 4 Hydrogen atoms and 2 Oxygen atoms on both sides. The "account books" are closed, and the mass is conserved! 3 Steps to Balance Any Equation
). These tell you how many molecules of that substance are involved. You balance equations by adjusting these numbers. A Quick Example: Making Water If you look at the raw reaction for making water:
: Add numbers in front of formulas to equalize the atom counts. It’s often easiest to save Hydrogen and Oxygen for last.
