Three things I learned in this unit one is what a solvent is . A solvent is a substance that dizzolves other materials. Another thing I learned is what a concentrated solution is. A concentrated solution is a solution with a small amount of solute compared to the amount of solvent . The last thing I learned is what a exothermic reaction is . A exothermic reaction is a chemical reaction in which more energy is given off than it is takin in. An example is wood burning. Those are some things I learned in this unit.

My most favorite thing was the chemistry in a bag lab because it was fun to see the bag blow up and to see how hot it got. My least favorite thing is some of the worksheets we did because I didnt find some of them interesting. One question I have is about a concentrated solution.
