KMnO4 Lab

*nudge*

We did sooooo much the lab was so enjoyable. I found it to be very educational about our current unit. Although it did reveal my lack of knowledge on the subject. The data we "collected" led us through the process of using molarity in stoichiometry. The calculations were a bit confusing at first but with a little nudge in the right direction I figured things out. I do still have a lot of studying in my future to prepare for the unit test.

Copper (II) Chloride and Iron Lab Day 2

Today we filtered out the fluid leftover. That left the copper. We then proceeded to mix in hydrogen chloride to help clean out the remaining copper. I was surprised to see how much copper was there after 24 hours. We left the copper out to dry until Tuesday when we will weigh the copper. We applied what we have learned all this time in the unit stoichiometry. We calculated the theoretical mass and on Tuesday we will divide the actual by the theoretical to get the percent yield.

Copper(II) Chloride and Iron Lab Day 1

After placing nail in solution

This lab was a great lab to show chemical reactions and their precipitate. I was fascinated by how fast the copper clung to the nail. We left to wash our hands and came back and the nail was covered by a thick layer of copper. The objective of the lab was to determine the charge of iron. Whether it was Iron 2+ or Iron 3+. In a few days we will be able to determine this based on our percent yield calculations.

Redox Lab

I found the lab to be a very fun lab and I learned alot. The practice was good preparation for the test. We got some strong reactions from calcium. Zinc, Lead, and copper didn't do much, but the still somewhat reacted. I will continue to study for the test coming up and I have high hopes for it!

Calcium

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.

Mixed chemicals

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.

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 on Aspirin Lab Day 2

My lab partner and I continued our lab today. We proceeded to take the contents of our mixture and clean out and filter away to get the crystals left behind otherwise known as aspirin. We weighed the mixture and left out to dry. The lab calmed down today and was more relaxed. I had a better idea of what we were doing and was more on it. We produced a pretty good amount of aspirin compared to the other groups, but there was one group with mounds of aspirin though. Overall we did pretty good in this lab.

Final Product!

Thoughts on Aspirin Lab Day 1

We took the pre-lab and I found it to be quite easy. My entire class that took the quiz on day 1 passed. My lab partner, Claire Frank, and I began our lab by collecting the ingredients and heating the necessary ingredients together and leaving it to sit for 24 hours. The lab was frantic and everyone was moving all different directions, so focusing was not too terribly difficult, but was still hard. We still managed to finish with a little time to spare. What I did find a little aggravating was how far off we were told to sway from the directions and there was some things that weren't in the lab directions.

Thoughts On The Forensic Archeology Lab

Tiny Square Pieces of Paper

Today we worked on the Forensic Archeology lab. It was tedious to say the least. My partner and I began by drawinga 24 by 24 square on a piece of paper and cutting out 576 boxes. I didn't exactly "enjoy" that part. After we were done cutting out the boxes we then put them in a cup and dumped them out. We separated the boxes with color facing upward and the boxes that are blank. Then counted them. Then restarted the process with the blank ones. Until we finished the required amount of trials. I know the point of the lab was to demonstrate halve lives, but there must be some other way to visualize the half life process. Despite all this I still learned quite a bit. :D

Beanium Lab

Beans

On Wednesday we conducted the beanium lab. I know I should have not expected anything more but I, for some strange reason, expected beanium to be some hybrid rare compound. As you probably know, my expectations were shattered when I saw beans on the lab write-up. When I conducted the lab I noticed that my calculation skills were refined and I thought that it helped a lot. Although I didn't like that the lab had to be turned in online because I find that writing things up by hand feels more natural. We found that the final average atomic mass was .304 grams per bean. All-in-all the lab refined my calculations and helped me practice.

Thoughts about the notes and our Lab

Circle with non-hidden line pattern

When we took the notes I was familiar with the material. I remember several things like atomic radiation,half life, and things like that. But the other things that were mentioned I hadn't the slightest clue what was going on. In regards to the lab, I questioned the objective. In regards to the lab itself my partner and I did well in identifying the hidden patterns by shaking the container and other methods like that.
