Mole Ratios in Chemical Equations
By Debbie McClinton, Dr. Miriam Douglass, Dr. Martin McClinton
Learners use the coefficients in a balanced equation to develop the mole ratios of reactants and products involved in the reaction. Five interactive examples illustrate the method, and students test their knowledge by working four problems.
Learners examine how melting, vaporization, and sublimation require energy input while freezing and condensation release energy.
