We adjust coefficients, not subscripts, to equalize atom counts on both sides of the equation. Coefficients must be in their simplest whole-number ratio to accurately represent the reaction. 00:00 Intro 00:36 Balancing equation 1 03:30 Balancing equation 2 04:44 Balancing equation 3 07:04 Summary Khan Academy is a nonprofit organization with the mission of providing a free, world-class education for anyone, anywhere.
