Welcome to the fifth week of the fourth marking period. Only 5 weeks of class left before final exams.

This week we are finishing up a short, but packed trip through Chapter 8. It is all calculations and I can truly say that the students worked really hard on them. Monday in class, we will do one last review & have the test on Tuesday.

Tuesday, 4/28--Chapter 8 exam

This is a calculations exam with 9 questions--one period exam.

--Be able to determine the Molar Mass of a compound (see sample problem 8h)

--Be able to calculate % Composition from the formula of a compound (see sample problem 8l)

--Be able to determine the Empirical Formula of a compound from % composition data (see sample problem 8j)

--Be able to determine the Molecular Formula of a compound from empirical formula data (see sample problem 8k)

--Be able to convert from mass to moles for a compound (see sample problem 8e)

--Be able to convert from moles to mass of a compound (see sample problem 8d)

--Be able to calculate the number of atoms or molecules if given the number of moles or the mass (see sample problem 8a)

--Be able to calculate the mass or number of moles if given the number of atoms or molecules (see sample problem 8b)

On to Chemical Reactions--Our last unit of the year. We have enough time to do a pretty thorough job with this topic.

But...There is lots to do and very little time to waste.

We'll be moving at a brisk pace--Be sure you keep up.

Encourage your student to work hard all the way to June 8

Chemical Reactions will be covered as part of the final exam.

The final exam will be 20 questions on new material (Chemical Reactions), and 80 questions distributed over the material from previous exams. (20 from each exam)

I suggest students begin reviewing as soon as possible.

There is a ton of material to review.
