important-2 questions! Type of bonding? Ionic,
Polar covalent, non polar covalent etc. Polar-
non polar??, Chapter 5 (check review 3) How
many atoms in some chemical formula Al (NO3)3
Ans13 Correct formulas for chemicals,
polyatomics Names of compounds molecular, ionic
compounds and Acids Chapter 6 and 7 Check
single/Double lab (9 and 10) Types of reaction?
Displacement, dissociation etc Balancing
equation- write the coefficients? Solubility
