Blog Week 32

On Monday, we talked a little more about the Nail lab. We wanted to know the reasoning for the rise in temperature of the test tube. We learned that breaking bonds requires energy and when energy increases, so does the temperature. The energy to break the bonds comes from the chemical energy. An exothermic reaction is when energy of the reactants were greater than the products, therefore extra leftover energy exited the system. An Endothermic reaction is when extra energy would need to enter the system before the reaction could take place. On Tuesday, we tried to do some worksheets in class, my group got number three. The picture below is our work:
On Wednesday, we had a sub and we were to do a worksheet. I didn't understand how to do any of it really. I did attempt a couple  for one I got PE + KE = U. Then I attempted number five and got a) increase b) increase c) increase d) decrease e) decrease. I need help understanding the LOL diagrams. On Thursday, we had a tutorial, because Mr. Abud won teacher of the year. Congratulations Mr. Abud! On Friday, we reviewed everything we've learned this year to prepare for the final.
