Vitamin C Lab

Today we started a lab in class using different juices to determine the vitamin C content in the beverages. We tested pear, apple, v8, a standard, and others to determine this. My partner and I still have other tests to finish up. Then we will determine which of the beverages have the highest amount of vitamin c.

Unit Exam

After that first quiz results, I was worried about chemistry this quarter. However, I prepared for this test in excess and the snow day helped with the preparation. I was able to do a lot more practice problems and it helped me prepare for this test. I feel confident about it and hope I can get more tests where I am this confident about it.

Stoichiometry review

Stoichiometry is the a section of chemistry that involves using relationships between reactants and/or products in a chemical reaction to determine desired quantitative data. We use one set of data to transfer information and find out how much is used of the other substance. This is important to know since this chapter uses it in some molarity problems.

Weekly quiz

We took a quiz at the beginning of the week and I thought it was pretty easy. But my scores did not represent that. I didn't do as well as I thought I would. It was over Molarity and I didn't get it all that well. I Understood the saturation graphs but the math and some of the other type of problems troubled me. I will study these topics more and get a better grade on the unit test. Here are some links to help with this chapter.
