CLASSWORK/HOMEWORK PAGE

The goal of this Homework Page is to post the homework assignments and their matching solutions. With the hope to get students to do the problems. Keep in mind that students need the practice working with the material to be able to work problems at a reasonable pace during a test/assessment. Note: Most of the quizzes and tests are open notes, hint hint the homework problems are part of the notes!

Stoichiometry problems require you to use several chemistry concepts that are all based upon the "Law of Conservation of Matter" and the two definitions of the mole.

Some tips:

1) Always check the reaction equation to see if it is balanced! If it isn't balance it! Remember ONLY CHANGE COEFFICIENTS!
a) Balance all the non- oxygen and non - hydrogen elements
b) Balance the hydrogen
c) Balance the oxygen last
d) If in doing any of the steps a prior element becomes unbalanced, increase the first element by 1 and
start over.

2) Use Molar Mass to convert grams to moles of a compound or element.
a) Use ONLY the subscripts to multiply for the grams of an element in a compound
b) DO NOT use the Coefficients to multiply for molar mass!
