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!

Reactivity Lab


Today's lab was easy and so was the pre-lab quiz. Out of all the solids Calcium reacted the most while Lead never reacted with and of the liquids. I do not think my lab group waited long enough for all reactions to occur and we may have missed some:(

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.
