Dimensional analysis

today we learned how convert one unit to another by using a formula. we also learned that counted quantities and exact numbers together have infinite significant digits.

Density=mass/volume

Density gas= G/L

Density solid= G/cm3

Density liquid= G/mL

k=c+273.15

f=9/5(c)+32

c=5/9(f-32)

Accuracy versus precision

Accuracy: refers to the proximity of a measurement to the true value of the quantity.

"every number written in scientific notion is significant."-Mrs. Frankenburg

today we talked about the difference between accuracy and precision. accuracy is how close the numbers are to each other. precision is how close to the target number it is.

Aspirin Lab 2

After you have mixed all of your chemicals your put it in a water bath.  Then add ice cold distilled water. Then let it sit overnight. If crystals do not begin to from then scratch the side of the glass to induce crystallization. Then separate out the aspirin.

Aspirin Lab 1

Today we finished making our aspirin. The process is fairly simple, first you start by getting your acetic anhydride (C4H6O3) and adding Salicylic Acid (C7H6O3).

Apsrin Lab review

Today we learned about the process of making aspirin. It seems pretty dangerous. So im kinda scared because we are handling dangerous materials.

Half life test

Yesterday I took the half life test. I understood everything on the test. It was easy and I feel like i did very well on it.
