Energy

I think it was different because it was something I have never done. I think that I learned that the kinetic is different from the potential. This is something I would do again. I think that it was was different from just taking notes. I would recommended it to do it again.

Chemistry


             Proteins contain Carbon, Hydrogen, Oxygen, and Nitrogen. It also had 20 or  more amino acids joining. Then it provides a structure and transport cells in or out. Lastly it helps fight off diseases.
     Lipids store more energy and wont dissolve in water. Then it steroids act like a messenger. Lastly they are made from gysoral heads and have a double or tripe bond. 
Carbohydrates are made from Carbon, Hydrogen, and Oxygen. Then it is a main energy source and break down sugars. Then a large molecules of many monosachrides are called pollysachrides. 
Nucleic Acids contain Carbon, Hydrogen, Oxygen, Nitrogen, and plus Phosphorus. Then it is formed by bonding of individual units called Polynucleotides.

Ice Melt Lab

In this lab we tried to melt ice. We took the temperatures every 5 mins then we took down what it was. My partner and I got 5 degrees Celsius before then on the heater we got 10, 15,20,30,40, then the ice was gone but we still took the temperature we got 65,80,87, 92, and 101 degrees Celsius. They were all Celsius.
We then answered questions:
1. The water did not boil or get hotter.
2. It is absorbing heat because the temperature is going up.
3. Released heat because the ice was frozen.
4. Your heart because it helps out your body heat. It goes off because of your chemical reaction.

Theirs our Graph we got when we plot it.

Chemical Reactions

Google Images

This lab we did was a synthesis reaction.

Part A: In the wool when we put it over the flame it burned and changed in the color. The equation is 4Fe+2O2 -> 2 Fe2o3.



Part B: In the baking soda when we put it over the flame nothing happened to it until it heated up and starting to make marks to burn. The equation is NaHCO3 ->2O+CO2+NaOH and its a decomposition. Then with the splint it goes right out to the top.



Part C: The nail in the chemical but the nail changed color and turned into copper. The equation is Fe+ CuSO4 ->Cu+ FeSO4 is a single displacement.

Periodic Trends

In class we have been studying the periodic table and trends. The group is the vertical columns in the periodic table. The periods are the horizontal lines. The periodic table is organized by the atomic number. The electron affinity is how much the energy is released. The an electron is added on to the neutral and negative atom. The ionization energy is how much of the energy has been removed. It will be removed from the negative atom. The electronegativity is that it decreases as the atomic number gets bigger. It also increases the distance between the valence and nucleus.

Flame Lab

Some metal ions can be identified by the color of their flame during the test. Different elements placed into a flame will turn the flame different colors. What metals do colors indicated?
Color:   Chemical Formula:  Name of Metal:
Purple- Kno3- K-Pattasium
Orange- COCl3- C-Colbalt
Red- Sr (no3)- S- Stratium
Green- Culc2- C-Copper
Yellow- Ba- B-Barium
Redish Yellow- LiNO3- Li- Kithium
Yellow Green- MgCl- Mg- Magnesium
1. What we were testing and the color that is produced.
2. It was not that hard.
3. They were all valiod.
4. The colors were purple, orange, red, green, tellow, redish yellow, and yellow green
5. K, C, and Li
6. What were are testing.

Law of Conservation of Mass Lab

We did a lab on Law of Conservation of Mass. The evidence we got from the chemical change is the color changed and it thickened. The last thing is that the gas produced. These were the observations we got when we were doing the lab. The matter can not be created or destroyed. This happens in a chemical reaction then changes its form. The substances can be two substances racted to two new substances produced called reactants. Produce   Products
