Iron Chloride Lab
On day 1 of the of the lab we did very simply steps. We simply had to get the mass of our equipment and mix together 50mL of water with approximately 7.50g of Copper(2) Chloride in a baby jar. We placed our nail in this mixture overnight and we will wait to see what happens.

Quiz
Today we had our quiz over this unit and I found it particularly challenging. The conversions seemed harder than the notes we did in class.
To help me do batter for the unit test I found some websites with practice problems and more in depth notes.

Day 2 Stoichiometry
There are 2 approaches to this lecture. Personally, I liked the second approach better. It was more compact and it was all one step. I did not understand the part of subtracting from the original to find excess reactants.

Day 1 Stoichiometry
Must always start with a balanced chemical equation and if in doubt convert to moles!

Redox Reactions
-driving force is electrons transferred
-losing electrons=oxidation(reducing agent)
-gaining electrons=reduced(oxidizing agent)
OIL RIG
(oxidation is lost, reduction is gain)
ELEMENTS REPLACE LIKE ELEMENTS, so non-metals to other non-metals and metals to metals
Synthesis- 2 or more reactants combine making 1 product
Decomposition- 1 reactant making multiple products
Combustion- oxygen as reactant, producing carbon dioxide and water
Redox for DUMMIES
Single Replacement

Unit Quiz
All together I thought this was a very easy quiz. Looking back I know realize I made at least one mistake. On question 6 you had to balance the equation then add the coefficients. You needed to put in two 3's to balance the equation, so the answer I choose was 6. However, I forgot to add the coefficients of one that were in front of the other products and reactants. Oh well, better luck next time.
