Different Solutions

Solution: A homogeneous mixture
Example: salt water

Suspension: A heterogeneous mixture with solid particles in it that are large enough for sendimentation
Example: Sand and water

Colloid: A substance that has been evenly dispersed throughout another substance
Example: Milk

Due to my calculations, it seems that there is a direct correlation between the ammount of molecules in a closed space and the pressure of the closed space, whether or not the species are light or heavy. The more molecules in the closed space, the higher the air pressure becomes. I also noticed that the more molecules that were in that closed space, the faster the molecules moved, thus increasing the temperature inside the closed space. Possible sources of error were not present because I did this experiment on  a computer.

Freakin' Chemistry in Action!!!

Question 1:
1a: double replacement
1b: synthesis
2 and 3: I think they might be some form of double replacement. I'm not sure though.

Question 2:
a. Hypoxia is when DO levels in an aquatic environment decrease so much that it becomes hurtful towards organisms living in the body of water.

b. Hypoxia reaches its highest levels in late summer in Long Island Sound. In the Gulf of Mexico it reaches its highest levels in mid summer while in some places in the gulf it can be year round.

c. The causes of hypoxia are increased nutrients in the water, eutrophication, decay of biomass on the bottom of the body of  the body of water, and oxygen depletion from stratification.

d. High levels of nitrate ions are caused by fertilizers, manure, animal feedlots, municipal wastewater, sludge, septic systems, legumes, bacteria, and lightning.

e. Safe levels are 10 mg of nitrate per liter of water. Excess amounts of nitrates in the body can lead to methemoglobinemia, a blood disorder that prevents oxygen from being delivered throughout the body.

Thermite Reaction

 A Thermite Reaction is when iron oxide and aluminum undergo reduction oxidation and form iron and aluminum oxide. The reaction is so exothermic that is melts the iron thus making it useful for underwater welding on pipelines.

The Reaction:

Fe₂O₃(s) + 2 Al(s) Al₂O₃(s) + 2 Fe(l)

Iron Oxide plus Aluminum gives Aluminum oxide and Iron

Another Single Replacement Reaction:

Zn + CuCl₂  ZnCl₂ + Cu

Zinc plus Copper Chloride gives Zinc Chloride and Copper
