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!
