New unit! Lesson 1 and 2:

Today we covered lessons 1 and 2. Lesson 1 covered toxins. Toxins are substances that interact with living organisms and cause harm. They can enter the body in a limited number of ways, they often react with water in the body. Toxins may be molecular, ionic, or metallic substances. We also learned a little bit how to write a interpretation of a chemical equation. For example:

NaCN(s)+HCL(aq)->NaCl(aq)+HCN(g) interpretation: solid sodium cyanide reacts with aqueous hydrochloric acid to produce aqueous sodium chloride and gaseous hydrogen cyanide.

In lesson 2, It was very short and we didn't cover much. Something important to know is that sometimes a change is described by more than one chemical equation. Also chemical equations allow you to track changes in matter on an atomic level. Also, there is some information that a chemical equation can't provide, and vise versa. That's all! Homework below :)
