For page 5:

The questions are answered on the videos but they don't just say the answer to # 5 is....
But if you are still having problems with these questions you can Google the answer or look in your book. Chapter 10 will help with page 5. On #7 you can look on this link
On #8 look on pages 175-177 from your book to refresh you memory on how to determine if a substance is polar or non-polar. Remember your answer from #7 to help you with which will dissolve in Water (polar substance).

For Page 6:

#3 Read page 441 from your book.
Here is an example: Sodium Chloride dissolved in water: NaCl --> Na+ + Cl- (Note: the equation has to balance as to number of atoms of each element and the charge on both sides has to be equal. In the example the total charge is zero on both sides of the -->)
#4 & 5: read page 403 from your book.

For Page 7:

#9 Remember where the cut off for saturated is on the graph.

For Page 8:

Remember "If you are looking for a fraction start with a fraction" -- "If you are looking for not a fraction start with not a fraction"

For Page 9:

MwVw = MsVs
Make your units cancel.

For Page 11:

When you are given a gas and conditions, you will be using pV = nRT or 22.4 (if you are given STP).
There is one limiting reagent problem on this page. All problems require a balanced equation (they have two chemicals in the problem)
Don't forget when you have two or more chemicals and the question asks "What is the Molarity?" do two steps. Step one is stoichiometry to moles. 2nd step is find the molarity.
