Sticky situations explore

Solvation is also called dissolution, and its the process of attraction between the molecules of a solvent and the molecules of a solute. Solubility is the amount of solute that can dissolve or dissociate a solvent. The process of chromatography is the figuring out the polarity of a substance by seeing how well it sticks to paper. Intermolecular forces are defined as the attraction of forces that molecules from different compounds feel based on their dipole moments (the polarity of the molecules). Intermolecular forces affect solvation because if the molecules have strong intermolecular forces, they don't solvate as easily as molecules with weak intermolecular forces. Cohesion forces are intermolecular forces that tend to resist breaking apart. A good example of cohesion forces would be hydrogen bonding because hydrogen bonding is a strong intermolecular force. Adhesion forces are intramolecular forces, which is the attraction between two different molecules. The term "like dissolves like" is employed to show that if a substance is polar, it is more likely to solvate in a polar solvent than a nonpolar solvent, and vice versa. This explains chromatography results by showing that the ink or dye will stick to the paper very effectively if it has the same polarity as the paper. If the dye doesn't have the same polarity, it will not be as cohesive.

This past week I've been catching up in my classes. I am getting better at scheduling and writing stuff down in my calendar. Also I applied for a vocal scholarship for Eastern New Mexico and got invited to a dinner to learn about New Mexico Tech.  I plan on improving my grades as finishing this semester strong and also eating alot on thanksgiving break.

Electrolysis Lab (again)

At the anode, the  reaction is 2H2O(l) --> O2(g) + 4e- + 4H+ which is the sight of oxidation. The cathode's half reaction, 2H2O(l) + 2e- ==> 2H2(g) + 2OH- , is the sight of reduction. The difference between the galvanic, or voltaic, cell and the electrolytic cell is the spontaneity. Galvanic cells are spontaneous, whereas electrolytic cells are not. Electrolytic cells require an outside energy in order to react, which means this non-spontaneous cell has to be hooked up to something that will give it voltage so there is an actual redox reaction. Galvanic cells can react on there own by being placed in their own aqueous solution and completed with a wire and a salt bridge to keep the solutions neutral. 
Calculations: For the amount of oxygen gas I got .00065 moles of O2 gas
                    For the amount of hydrogen gas I got .0026 moles of H2 gas

3 questions #7

This new section is all about gas pressure and volume and temperature. Its alittle hard to grasp but I am slowing understanding. I learned which variables are direct and indirect relationship-wise. I also learned alot of new laws and measurements that I never quite learned before this class. I plan on adding onto how much I know about measurements and memorizing the different laws.

3 questions # 6

1. I have learned a lot about how batteries work, I did really well in the last section all about electrochemistry. It made sense to me which was quite surprising. I got a 75 on the test a a perfect score on the quiz, and I am very proud. I plan on applying my newfound understanding to the next section.
