Solubility Lab

To start off this is the first time a easily passed the pre-lab quiz but from the looks of it I didn't have to! Everyone got in even if they failed it. I thought this lab was quite interesting except for the fact that I felt more like a factory shooting out chemicals and it wasn't easy to actually observe. However I did gain better understanding of the solubility rules and reactions.

Solubility Rules

So now we all know about those super hard to remember Solubility Rules. At first I had no idea how or what to do, but as I researched them on my own I found them less and less confusing. I soon found a very simple photo, but the problem was is that it was missing some of the rules. So I used the rules Mrs. Frankenberg gave us and used them to add on what was missing. The end result is the picture below.

Balancing Equations

Finally something I enjoy! Balancing equations for me has always been super fun and easy. I personally don't find it confusing at all. I like how we have to make sure there is an equal number of each element on either side of the yield sign. In the end it feels very satisfying to have the equation balanced. I also like how each element sometimes make you change the entire formula. It may be frustrating for others, but not for me!

Formula of a Chloride Lab

This lab was my first to actually participate in. It was very fun and the whole lab was quite easy also. For measuring the watch glass I did one measurement with the watch glass and without and with the zinc inside to make sure there is no change in mass because of the watch glass. I found that there was only a .0002 difference so a very negligible amount.

Failing pre-labs is not fun...

We had a prelab where we had to choose A or B a seemingly unimportant choice but for me it was certain failure. I did not understand the math so much and so when I chose B my partner got the easy A question with words. I got the not so fun math portion and sealed the fate of my group. I failed the question and ended up ruining the lab. I felt really bad and even more so confused and grustrated because I didn't understand the question.

Empirical and Molecular Formulas

Empirical Formulas are really nice. I like how they are the factored version of Molecular Formulas. Empirical formulas being the lowest number ratio of elements is more of a unit of the Molecular Formula. This helps you to understand the chemical better and understand how the elements act with each other. I also realize a common connection between the two types of formulas is the common % composition which is kinda a given.

Acid Base Reactions

In an acid-base reaction the driving force is the creation of water. This is pretty neat because you wouldn’t (or at least I wouldn’t) of thought water be a part of an acid-base reaction, I just find water to be a little mundane and acids and bases a little more complex. Anyways, for acids and bases to do certain things they need to be either strong or weak acids and bases. I have a feeling this factor is not going to be fun to understand.

Moles

We learned about moles in class to and I find them quite interesting. They create a unique bridge to allow us to easily convert from mass, atoms, and volume. However annoying this is to do in class it is without a doubt very helpful. I also love converting so maybe its just me.
