The test will cover the following chemistry concepts: 1. The nature of elements, compounds, mixtures and pure substances including identifying and describing them as well as comparing and contrasting them. 2. Identifying and naming ionic and covalent compounds using proper nomenclature rules. 3. Applying the law of conservation of mass such as balancing chemical equations and determining amounts of reactants and products. 4. Identifying types of chemical reactions and interpreting solubility graphs.

7. Naming Ionic and Covalent Compounds
IONIC COVALENT
• Metal + nonmetal (-ide)
• No prefixes!
• Use the “criss-cross” method
to determine number of
elements
• Nonmetal + nonmetal (-ide)
• Use prefixes to indicate
number of elements
• Mono-
• Di-
• Tri-
• Tetra-
• Penta-

8. Naming Ionic and Covalent Compounds
How to determine
charges for ions

9. Law of Conservation of Mass
Balance this equation.
Mg + HCl  MgCl2 + H2
If 20g of magnesium react with 30g of hydrochloric acid
and produce 46g of magnesium chloride, how much
hydrogen gas was produced?
