Lesson Plan: Reaction Masses Chemistry • First Year of Secondary School
This lesson plan includes the objectives and prerequisites of the lesson teaching students how to calculate the masses of reactants and products using their formula masses, molar quantities, and ratios.
Objectives
Students will be able to
- calculate the molar ratio of reactants to products, and other reactants, using balanced chemical equations,
- combine formula mass with actual mass to determine the masses of other reactants and/or products,
- use balanced chemical equations to calculate the masses of reactants or products,
- use the masses of reactants and/or products to determine balanced chemical equations for reactions,
- use balanced equations to calculate the mass of a reactant or product from the number of mole (and vice versa).
Prerequisites
Students should already be familiar with
- formula/molar mass,
- mole calculations,
- conservation of mass,
- balancing equations.
