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! 

More links for the test

Here are some more links to help you on the test that i found today! I hope they help!

Scientific Notation

http://www.proprofs.com/quiz-school/story.php?title=significant-figures-and-scientific-notation-practice-quiz

This photo, as well as quiz, helped me review and study when learning scientific notation. Scientific notation is important to know and not something to just pass over since we will be using it for the rest of the year. I'm not worried too much about how to write scientific notation though considering I remember it from physical science. I hope this helps! 

Aspirin Lab Day 1

 

Today, once my lab partner and I passed the prelab question, we conducted the first 4 steps in the procedure for making aspirin. We used 5mg of salicilic acid, and carefully put 7mL of acetic anhydride into that flask, then put the flash into a hot water bath for 15 minutes. The substance turned dark green, then brown once we added the 8 drops of sulfuric acid. The crystals are normally supposed to be white, but hopefully our crystals will turn out well tomorrow!
