Chemistry I Final Exam Review

Chemistry I Final Exam Review Part 1

By llanham summitt

Timers are turned off so that you can relax and think about the questions and take your time.

​

Chemistry take thought and carefully reading.

​Take you time and read carefully!

The periodic table. the polyatomic ion chart, the mole conversion chart and your calculator are available to you; USE THEM.

​

​rely on your resources not GOOGLE or others.

Use your resources!

​

You can do this if you try!

Effort is an important part of anything that you do..

“The average person puts only 25% of his energy and ability into his work. The world takes off its hat to those who put in more than 50% of their capacity, and stands on its head for those few and far between souls who devote 100%.” ~ Andrew Carnegie
