Acid Base reactions

https://www.youtube.com/watch?v=ANi709MYnWg
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!

The Mole

https://a-woods.wikispaces.com/file/view/molar_roadmap.gif/251028280/800x515/molar_roadmap.gif

Yesterday and today in class we learned about the unit of measurement, the mole. Molar quantities are measured in this. Dimensional analysis, which is what we learned last unit, is an extremely useful skill when converting chemical compositions in this unit. So far i have understood most if not all of what we have learned so far this unit, but ill still be studying!

Pre test frightening fears

As many of my peers have said, the pretest for this unit made absolutely no sense. I don't remember learning about any of what was on the test. I know that I need to make sure I'm studying and asking questions to get through this unit! 

Also, after our first lecture today, some if not most of what was on the test made more sense from our lesson about the mole today. I will have a later post explain what I've learned about the mole!
