1.) A concentrated solution is when there is a large amount of solute in the solution and not as much of the solvent. A dilute solution is when there is a little amount of solute and more solvent. 2.) The difference between a strong and weak acid is that a strong acid reacts a lot with water and a weak acid reacts very little with water. 3.) []

When the chemical system reaches equilibrium, all concentrations remain constant because when the reactants turn to products, the products are turning into reactants at the same rate so that there is no loss in reactant and product concentrations. This also explains why an equilibrium is dynamic. Even though the concentrations remain constant, the reaction is still taking place. It is just the reaction from product to reactant and reactant to product reactions are happening at the same rate. When equilibrium expressions are written, the product concentrations are written over the reactant concentration. The brackets [ ] represent the concentrations of the products and reactants.

Homogeneous: N2(g) + 3H2(g) <--> 2NH3(g) K= __[NH3]2__ [N2] [H2]3

Heterogenous: PCl5(s) <--> PCl3(l) + Cl2(g) K= [Cl2]

1.) Oil spills can be cleaned up by burning the oil on top of the water. They usually do not do this because it causes very bad pollution. An airplane can fly over the oil spill and drop chemicals on the oil spill. Those chemicals break down the oil into the ocean. Some oil spills on beaches are simply cleaned up with shovels and other tools. 2.) Solubility- The quantity of a particular substance that can dissolve in a particular solvent. Rate of Dissolution-The speed at which a solid dissolves. Temperature speeds up these processes because the molecules are moving faster, which makes it easier for them to break apart. Stirring speeds up these processes because you are forcing the molecules to move apart from each other. Surface area causes these processes to speed up because the bigger the surface area, the quicker the solubility or rate of dissolution. When there is a large surface area, there is more room for the molecules to dissolve.

1. Boiling Point- 100 Degrees Celsius- The boiling point of an element or a substance is the temperature at which the vapor pressure of the liquid equals the environmental pressure surrounding the liquid. This property is unusually high. 2. Surface Tension- Water has the ability to support small objects. The hydrogen bonds between molecules cause a film to develop at the surface. Other molecules do not have surface tension. 3. Cohesion- This means molecules like to stick to each other. This is why we find water droplets in perfect spheres, which is similar to other molecules. 4. Molar Mass- The molar mass of water is 18.0153 g/mo. Molar mass is the mass of one mole in a substance. This is low compared to other molecules. 5. Ability To Dissolve- Water is a universal solvent. More substances will dissolve in water than in any other liquid. Both polar substances and ionic substances.

When energy from the sun hits the earth, much of the energy is absorbed. Once absorbed, the absorbed energy is sent back into the atmosphere. Because of the greenhouse gases, CO3, O3, H2O, and CH4, most of the energy is trapped in our atmosphere causing our earth to heat up, because all the molecules on earth now have a higher kinetic energy.
 * Wiki Assignment #3- A Global Warming?**

1.) I've heard that what were experiencing may not just be global warming, but climate change, because some places are getter warmer and some colder. 2.) That global warming is coming so fast that animals and plants might not be able to adapt.

I chose this video because we actually talked about fusion for awhile in class. I wanted to expand on what i knew about fusion already. This man talks about the planet being dominated by resources such as: oil, coal, electricity, gas. He exclaims that the world is using up these resources faster and faster and faster, and that we desperately need new technology to feed these addictions: Fusion. It doesn't take up much space, doesn't leave space, and it's safe. Fusion is so great, because we have enough for 30 million years. What I've learned from this video is that if we can some how do a fusion reaction, we can end our world energy crisis. It is said fusion is 30 years away and will always be. I think if everyone puts their minds to it, we can solve this matter a lot sooner than expected. [|Fusion is Energy's Future]
