Chemical Reaction Quiz

I took the chemical reactions quiz. Despite the hours of studying I did I still found it to be somewhat difficult. The balancing ones were beyond what we discussed in class. I guess I wasn't ready for everything. The net ionic ones were somewhat easy. Probably because that's what I thought the test was gonna be over. Solubility rules, not everything else. I guess my reflects that. I would like to retake it, but I guess that's out of the question. I know one things for sure, I will be ready for the unit test.

Eh

Solubility Lab

Yesterday in class we performed the solubility lab. To be 100% honest, I felt the lab was a little disappointing. All we did was mix 10 droplets of varying chemicals into a tray and see if there was a chemical change. It just reconfirmed the predictions I had made, so it was pretty much a waste. It was also very time consuming having to refill each dropper, and you spent more time cleaning than anything else. I mean, maybe I learned through practice and experience, but I can't say I found it enjoyable.

She did a great thing today. She postponed the lesson! I now feel amazing! This gives me an opportunity to work on my blog. I was a bit worried about this lesson, but she got rid of those worries and helped me out.

Chemical Composition Unit Test

When your test grade finally hits you

Today I took the unit test. I heard from previous hours it was hard, but I frankly found it to be only somewhat challenging. The only problem with that test was that it was very time consuming. As soon as I got my test I took off and finished the test in no time. Only on 1 I couldn't figure it out until I came back to it and re-read it and figured it out. Although there was somethings on the unit test we didn't even cover I think I was still able to figure it out using a different equation. Overall I can see how people had trouble with it because it was very troublesome.

Chloride Lab

Chloride

We mixed hydrochloric acid with zinc and measured the results. We calculated the ratio of the 2 element. We drove off the chlorine gas from the mixture with a heat plate. That left zinc chloride behind. I found the lab to pretty easy and entertaining except for the fact that the chlorine gas smelled terrible. The pre-lab I didn't expect to do good on and I apparently pulled through and passed it. This just shows how much I am going to have to study for the test over chemical composition.

Before Heating

After Heating

Hydrate Lab

Lab

We took a hydrate compound and drove the water off by heating it with a Bunsen burner. The lab itself was pretty easy and I understood the purpose and the lesson of it. The only thing I found to be a little difficult was the pre-lab. I got the procedure question so I found it to be easy. I calculated the math question for the practice and got the correct answer, but I didn't fully understand every single step which is what I found tricky. Overall the lab/pre-lab were pretty easy, but I feel like the test will be much more complicated. I see quite a bit of studying in my future.

Thoughts About The Pre-test

Question Mark

I don't think I've ever had to take a test where I knew absolutely nothing. This was a first. I knew the unit mole and that's it, the rest was completely blank. I tried on the first 5-10 questions, but after that I knew there was no point, when I would try I could never get anything close to the options. I would always get calculations that were just way far off from the numbers. I saw everyone else finishing and so I thought I was getting caught behind so maybe I need to pick things up, but when I looked closer they were just filling in random bubbles because I can only assume they were in the same situation as me. I'm sure there were some people that were familiar with the content. I now know I have my fair share of studying to do this unit!

Project Final Thoughts

Whack-A-Mole

Coffee Cake

I finished my recipe conversion project and found it to be much easier than I thought. I thought it was going to take me several hours of work, but it took me a mere hour even from all the typing. Once I finished the unit conversions I had to bake one of the recipes. I picked my all time favorite Coffee Cake. No it doesn't taste like coffee. Might I say, I thought it came out quite well. When I brought it into my 6th and 7th hours I couldn't keep people from eating it. I even gave some to my teachers! It was the most fun I've had on a project in a long time.

Fridays thoughts

Feast!

On Friday we brought in then food we baked. I personally wasn't sure how my food was going to come out because my mom normally bakes it but she wasn't home, so it was a struggle to say the least. Overall my food came out great as did everyone else's. I did notice how overwhelmed I was with chocolate desserts and cookies. I've had enough chocolate for awhile. I tried to make my way around trying everything, but I got full half way around the classroom. Hopefully we have a third Friday in a row where we eat food!
