End of unit

As the unit comes to an end with the unit test today, I feel pretty good about most of the subjects. There are a couple things that I may need to study harder for the final, but I feel more confident in ending this unit than I did last unit!

Redox Lab

In this lab, we again combined two substances, but this time one was a solid metal and the other was an aqueous solution. This lab helped me to visually see what happens when a reaction occurs showing a color change, a formation of a gas, or bubbling. Some reacted, but almost half didn't. All and all, I enjoyed this lab! 

Acid Base reactions

Acid Base reactions occur when water is  the riving force in the reaction. The products include "salts" and water. There are rules for strong acids strong bases as well as weak acids and bases. The video link attached is a video from crash course chemistry on the subject and helps explain further with helpful examples. I hope this helps!

Chemical Reactions Lab

In lab on Friday, we used two aqueous substances to mix together to show the formation of a precipitation. I enjoyed this lab because it showed me first hand how some solutions can form solids and some may not! Either way it was an interesting lab! 

Balancing Chemical Equations

http://www.wikihow.com/images/2/2f/Balance-Chemical-Equations-Step-6-preview.jpg

In class yesterday we learned about how to balance chemical equations, which i remember from physical science so it wasn't too hard to pick back up. The main thing to remember is too make sure that you have the same amount of elements on each side since in chemical reactions, elements don't just appear out of no where, although they can form new compounds. I know this unit will get harder as we go along, but so far its not too bad!
