Scientific Notation


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!

Helpful links

As I'm studying, i have been placing links, pictures, and videos that may help others for this upcoming Unit test here:
http://www.chem4kids.com/files/atom_structure.html - here is an easy outline of the atom's structure

https://chemistry.osu.edu/~woodward/ch121/ch2_atoms.htm - table and site that will go more in depth with atomic structure

http://vignette2.wikia.nocookie.net/schools/images/0/0b/Chart.JPG/revision/latest?cb=20060611033958 - here is a picture that will hopefully help outline most of the aspects to radioactive decay

here is a useful link and video that will help outline and explain the different types of decay

http://chemed.chem.purdue.edu/genchem/topicreview/bp/ch23/modes.php another link to help with radioactive decay

https://www.khanacademy.org/science/chemistry/atomic-structure-and-properties -khan academy is a excellent site to explore the atom in different ways and videos

https://en.wikipedia.org/wiki/Plum_pudding_model i had trouble with the difference between Johnson's model and the rest, so i hope this link is helpful


I hope these links, pictures, and videos have helped you study just like they helped me.

Post- Weekly quiz #1

We took the first quiz of the atomic structure and radioactivity today and i felt like i knew the majority of the content. I realized afterwords that i did not calculate the average atomic mass correctly, but i now reviewed the equation and have corrected my mistake for the unit test. Otherwise, I have understood this unit and haven't had very many problems so far.

Beanium Lab


Today we did a lab replacing isotopes and atoms with beans. This lab helped me understand the total average mass equation that we learned yesterday because I was physically working out the problem and visualizing the beans as the isotopes. I also learned that the total average mass of the four isotopes should be closest to the more abundant isotopes mass.
