Chapter 8 Worksheet #2
Name KEY!!! #2
Your instructor used the following symbols for phases on this sheet:
(s)
(l)
(g)
(ppt)
(aq)
Anywhere where you don’t see phases, your instructor determined that phases in that equation would be difficult for students to do, so he didn’t list them for that
example. Please note that your instructor replaced the balancing numbers with types of reaction; see key #1 for those numbers.
Please note that your instructor named all the chemicals that it would be appropriate for you to know how to name. Acids (chemicals that start with the letter “H”
in the formula), get named just like ionic compounds at this point of the course – name the front, then name the back.

Here are three things that you can do to do
better on your chapter 8 test.
1. On the front of this page, write names underneath the chemicals.
2. On the front of this page, write phases behind each chemical.
3. On the front of this page, identify the types of reactions.
