For those of us who still need help with grasping RedOx reaction, I have found a website that I fell will be most helpful, especially with the upcoming test.
Today we learned about RedOx chemical reactions. While this may be easier than double replacement recations, these are still hard to get. As long as I pay attention to what metals/nonmetals react with, I should be fine.
Today we had our Solubility Lab. It was really neat seeing how the chemicals react with one another and how quickly they react. I was able to get some pictures of some of the chemicals mixed together and I put them below.
I am starting to understand empirical formulas more, but just in case others are still struggling, here are some helpful websites to refresh your memory.
I think I am speaking for the majority of the class when I say that the Chemical Composition exam was one of the hardest we have taken this year. It was stressful and not very many people finished before the bell rang. Some of us still may have trouble, so I have found a video and a website that can help people if they so wish.
I have found a helpful website for understanding empirical formulas. It has examples with work shown. I hope that people will find it to be resourceful.
We have been learning all kinds of uses for dimensional analysis, such as converting elements as well as compounds. I have found a useful website to help remember the rules of D. A.
