Jayleen's Chemistry Blog

1. I recently completed my blog entry and my UT online homework 2. I recently learned the difference in chemical and physical changes and properties 3. To improve my understanding and reinforce my learning I plan on taking more time to study over my flipped notes

1. We were trying to answer the question "Which changes are examples of a chemical change, and which are examples of a physical change." We want to answer this question because physical and chemical changes have different properties that tell them apart, which we are trying to answer. 2. During our investigation we mixed and heated multiple different kinds of elements to see the changes it caused. We conducted this way because it gave us obvious answers to our question. 3. Claim: Something new and different that wasn't there before is an example of a chemical change. When it stays the same and nothing changes it is an example of a physical change.     Evidence: Water & salt = Salt disappeared Copper & heat = color changed NaOH & CuNO32 = became a solid HCl & NaHCO3 = Fizzed Wax & hot water = liquid from a solid     Reasoning: •Salt & water was a phys. change because the salt only disappeared because they were mixed so nothing new c

1. I just finished my density lab packet and flipped 1.2 2. I recently learned the pacific Atlantic rule for sig. digs. 3. I plan to visit Ms. Gardeners website more often to get more familiar with the why the class is taught and things pertaining homework and class work.
