Chemical Reactions Week 3 Post #2

Test Day. The two most dreaded words. I was extremely nervous for this test because I had done so poorly on the last one and I couldn't afford to fail another test. Going into this test I felt more confidant about my knowledge and understanding of the material and I'm hoping my score will reflect that. I will admit there were some questions that I didn't know how to answer but I gave it my best shot and moved on to the questions I did know how to do. I'm nervously awaiting the day when our tests are put in the grade book, wish me luck!

Yesterday we got to do the metals lab. It was actually pretty fun and easy, all we had to do was put 6 different metals in six different well plates and then add a solution to the well plates and watch for a reaction. Sometimes it took as long as 10 minutes for the reaction to take place, but not all the metals reacted each time. The only metal that reacted every time was Calcium. Then once we had seen all the reactions we created our own activity series based upon the reactions of the metals. Overall I liked this lab and it was fun to see what metals would react and which ones wouldn't.

Tomorrow is the dreaded weekly quiz. I feel more prepared for this quiz than the last unit test, and after getting my score on that test, I'm definitely going to spend more time studying this time around. Below are some links I found super helpful for studying:

CHO Method

Types of Chemical Reactions

Practice Balancing Combustion Reactions

Practice Balancing Chemical Equations

Redox reactions

Assigning Oxidation Numbers

On Friday we did the Solubility Rules Lab. I was worried because my lab partner had already said she wouldn't be here, but the lab turned out to be really easy, so I was relieved. For the lab we mixed two different chemical compounds together to see if it made a solid. Since I had already completed the data table, I had a pretty good idea of which ones would react and which ones wouldn't. I was right except for about 2 of the chemical combinations. Overall I liked this lab and it was pretty fun.

These are some of the reactions we got to see take place!

Finally!!! Something I understand!! Today we learned about balancing chemical equations, which is like the one thing I actually remember from physical science. Not only do I remember it, I remember how to do it, AND I'm pretty good at it! I'm so glad for this unit because I really need this breather from learning all knew information at a fast pace. Yes, I know we will build on this information and it will get more complex as the unit goes, but I'm hoping that since I have a solid understanding of the base material I won't have such a hard time when all the complex stuff gets thrown at us.
