 * The difference between a dilute and a concentrated solution is that in dilute solution, the ratio of the solute to the solvent is smaller than half. In a concentrated solution, the ratio of the solute to the solvent is larger than half.
 * A strong acid is where almost every particle of the HA molecules react with the water to form hydronium and A+ ions. A weak acid where very little of the HA molecule reacts with water.

 * An example of an equilibrium is two kids going up and down on a teeter-totter (Seesaw), when one kid goes up the other will go down. This is an example of an equilibrium because the kids are constantly going up and down to the same height and around the same speed. It doesn't exactly match a chemical equilibrium, because you can see the kids changing height and direction. But, besides that the two are almost exactly alike, because the both are constantly changing, there are two opposing forces and the are both equal.

 * Concentration effects the reaction rate, because the higher the concentration of one of the chemical the more collisions there will be, because there are more particles. If there are more particles moving around then they will run into the other chemical more often.
 * Temperature effects the reaction rate, because it speeds up the particles making it more likely for them to collide more often and more times.
 * A catalyst effects the reaction rate, because it lowers the activation energy by giving the particles another way of reacting. A metaphorical example is having a mountain in between two valleys, only people who have enough energy can make it to the top and back down the other side. But, if you build a tunnel through the mountain, it gives people an alternative path to the next valley because it takes less energy thus less time.
 * Surface area effects the reaction rate, because particles need to collide to react, but if the particles are surrounded the can't react with the other particles. But if the particle has a side open or if there are less particles to react to get to it the reaction rate goes up.

 * Water in a pure state has a neutral (7) ph, so pure water is neither a acid or a base. Ph is a measure of the strength of an acid or a base. A neutral solution has a pH of 7; acids a pH between 0 and 7; bases a pH from 7 to 14.
 * Water is a universal solvent. It is able to dissolve a large number of different chemical compounds. This feature also enables water to carry solvent nutrients in runoff, infiltration, groundwater flow, and living organisms.
 * Water has a high surface tension. In other words, water is adhesive and elastic, and tends to aggregate in drops rather than spread out over a surface as a thin film. This phenomenon also causes water to stick to the sides of vertical structures despite gravity's downward pull.
 * The freezing of water molecules causes their mass to occupy a larger volume. When water freezes it expands rapidly adding about 9% by volume.
 * Fresh water has a maximum density at around 4° Celsius. Water is the only substance on this planet where the maximum density of its mass does not occur when it becomes solidified.

 * Global warming is a very controversial subject, but the Green House Effect is true and there is evidence to prove it, even on the molecular level. Most of our atmosphere is made up of diatomic or single atoms, oxygen, nitrogen and argon, but their are some that have more atoms, such as CO2 and H2O. But, all molecules can vibrate, some more easily than others, due to their bonds. The bonds can expand, contract, and even wiggle, which can cause the charges to shift within the molecule, only within molecules that have more than two atoms in the bond. Light is caused by a vibrating electron emitting photons, and molecules can act the same way, its atoms can absorb and release energy, or waves, too if it's at the right frequency. Sadly, most of the energy, Infrared waves, is at the right frequency of the molecules that can emit it back out, but it can emit it back towards the earth to have it heat the earth even more, causing Global Warming.

__**1.**__ Inside the Mind of a Killer
 * I chose this video because I really like crime shows like CSI, Bones and Fringe, so the topic really interested me, and it was a topic that I didn't know much about.
 * The presentation that Jim Fallon gave, was on how one becomes a psychopathic killer and how someone can see or determine if you are one or might become one. There are three main things that can cause this, their environment (very violent), genetics (if violence runs in the family and if boy or girl), and finally if he/she has brain damage. The way to see if you are a psychopathic killer is by a PET scan of the brain and if you have damage to the orbital cortex (right above your eyes and it controls your decision-making skills and your emotions) it is a high possibility that you might become a murderer or even a psychopathic killer.
 * Everything I saw in the presentation was something I didn't know except that your environment can effect your behavior as an adult. I learned what the orbital cortex is, that genetics effects your behavior and that you can actually see if someone is a killer or not.
