Lab day 2

So we came back after the weekend and after doing the calculations my group got Iron (II) Chloride! The color of the liquid was really weird and gross so thats cool. Also the copper was almost like a dried foam texture so that was cool too!

Lab day 1

Today we started the Copper (II) Chloride lab, I passed the pre-lab quiz with no problem. For day one we weighed a baby food jar, some CuCl2 and dissolved it in water to make it aqueous, and a nail. IN the lab the Copper Chloride is supposed to react with the iron nail to make solid copper and Iron (II) or (III) Chloride. Thats the interesting thing about this lab, you can get either one, I'm excited to see our results.

Limiting Reagent

Today we learned about the limiting reagent . I understood this lesson surprisingly well, and this website has a very good simplified explanation of limiting reagent, its crazy to think that we only have a we more days till finals... It scares me a bit...

Stoichiometry Start

So today we started new unit, Stoichiometry. Just from what we are doing right now it doesn't seem all that difficult. I get it but I watched this video for enrichment to make sure that I do understand it. I'm excited for this unit, and more excited for christmas break but finals are in the way of that...

Test

I feel like I did fairly well on the test, I finished very quickly and spent the rest of the time going over the test making sure my answers were correct. Unfortunately I forgot some polyatomics and I'm sure of it so I'm studying those to no end right now, I'm using quizlet to study them. Also I need to make sure I know how to do volume questions as I am still a little shaky on them. Other than that it felt pretty solid! EDIT: I got a 77% so not bad!

Metals Lab

Yesterday we did a metal lab, it was showing us single replacement. It was really cool, we took a metal then added a few drops of a solution then observed the reactions, calcium was a very reactive one, it bubbled and changed colors with every solution. On the opposite end of the spectrum lead reacted with none of the solutions. Cleaning out the well plates proved to be a bit more difficult than anticipated but with a little bit of elbow grease all was well. Our unit test is tomorrow so I'm watching another video on redox to make sure I get it.
