The number placed in front of a formula is called a coefficient. The small number within a chemical formula is called a subscript. Why do we adjust coefficients when balancing chemical equations and not subscripts?

Now click on "Game" at the very bottom of the screen. Choose at least 1 level of the game. (fyi: level 1 is kinda hard)
Click on Show your Work and record at least 3 balanced chemical equations with coefficients.
(Note: You will want to try these on paper too if it helps you balance. You'll need to know how to get the coefficients for your quiz.)
