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.

Redox

(Yes I realize this is 2 posts the same day but I feel I gave a reasonable argument as to why in my last blog posts here)

So I was absent during this lesson so I'm going off of my neighbors notes and what the internet tells me so I may not be exactly correct. These videos really helped, and the redox reaction wiki page helped too.

Redox is a fancy name for an oxidation reduction reaction, and that's a fancy way of saying an atom is loosing electrons and another is gaining electrons. The anion is being reduced and is gaining an electron, and the cation is loosing an electron and being is oxidized. LEO says GER, Loosing Electron Oxidized, Gaining Electron Reduction. There is synthesis where 2 atoms come together, single replacement where the metal is replaced, decomposition where a compound is split, and combustion is when a hydrocarbon reacts with oxygen gas the products are ALWAYS H2O and CO2. In order for the reaction to occur the charge on the ones that will replace each other must be equal.

Finally Back! (Lab)

I haven't made a blog post in so long! The reason I haven't is because I was sick Tuesday the 24th the last day of school before the long break. That made me miss the redox lesson which you can see my blog post on that here. Anyways I got better on thanksgiving but my computer decided to completely break to the point where I couldn't even turn it on, so no blog post Thursday. Then I went out on Friday and get a great deal on a laptop so thats what I'm making this blog post on. Now to the actual educational part of this blog, we did a double replacement lab in class awhile ago and it was really cool. In the lab we would take 5 drops of one solution then add 5 more drops of another solution and we would observe if a solid was formed. Below are a few pictures I took during the lab and thats all i have for this post!

First Lesson

So we had our first lesson of this unit yesterday it was pretty basic, just balancing chemical equations which is just making sure you don't get numbers messed up. I'm writing this on my phone right now so I'll add links and a picture once I get home on my computer. This unit it seems like we won't be doing as complicated numbers as the last unit, so I'm ecstatic about that.
