Unit 2-Mass Relations in Chemistry

Key Learning Targets

1. Students will become more familiar and comfortable with dimension, scale, and the models and abstraction necessary to deal with the sizes of molecules and the large number of molecules involved in the processes that surround and sustain us – The Fundamental Unit of Matter (“the mole”).

2. Students will be able to determine when a chemical reaction is taking place and be able to write word and balanced formula equations for the basic types of chemical reactions, using coefficients.

3. Students will be able to use chemical equations to predict and calculate quantities of reactants and products needed in specific chemical reactions (stoichiometry).

Grams, Moles, and Atoms/Molecules

Student will be able to illustrate how chemists count atoms and molecules and to identify whether this counting by weighing method is accurate.
