Copper Lab Day 1


Last week we began the Copper Lab that involved reacting together iron (in the form of a nail) and copper chloride. We first had to take the mass of both the baby jar and the nail, then add the copper chloride to the jar. Then we polished the nail and added it to the jar. Almost immediately the reaction began to take place and copper started to form. We set it aside for the weekend and will address it this week.

Magic Number Method

This method was a life saver for me and I hope they can help some other people. It basically transforms stoichiometry into one large algebra problem. These links really helped me!

Copper Lab Day 2


Yesterday we completed the copper lab, which reinforced our understanding of chemical reactions and their composition. When we combined iron with copper chloride, we produced an ugly solid copper. These labs really help me picture the reactions and makes it easier to calculate and determine answers.





Unit Quiz

I felt very confident while taking this quiz; however, my score suggested that I need to study more for the exam. I am still struggling with determining the limiting reactant and excess amounts. These links really helped me study and practice more.
