3.Mass Relationships in Chemical Reactions

3.1

• Visualize bonds broken and formed in a chemical reaction and relate numbers of molecules or atoms to the balanced reaction.

3.2

• Balance a chemical reaction, given the formulas of reactants and products.

3.3

• Calculate formula weight, molecular weight, and molar mass, given a chemical formula or structure.
• Interconvert between mass, moles, and molecules or atoms of a substance.
• Relate the amount (moles or mass) of reactants and products in a balanced equation using stoichiometry.

3.4

•  Calculate percent yield, given amounts…
