Homework on bond discovery

Facts on Bonding Discovery
      When applying strain to the atoms they become more chemically reactive
       The application of strain also results in structural changes
       Since the strain affects the reactivity level, chemists will be able to alter chemical reactions to get different results
        This discovery allows chemists to be more selective in the manufacturing process of certain things
     

Dry Ice

Dry Ice
     -Dry ice is solidified carbon dyoxide.
     -It is made by pressurizing and refrigerating pure CO2 gas into liquid CO2, and than letting it expand again, and then pressurized into shapes.  ie: cubes, pellets...
     -Dry Ice has many uses, such as removinf floor tiles, to purge fuel tanks, to pack freshly caught fish, and many other uses, like creating a fog in a movie...etc.
     -The "smoke" that is created from dry ice is really the gaseuos form of CO2.  Since CO2 normally skipps its liquid state, the ice does not melt, but sort of just evaporates from being a solid.
    -Dry Ice is an average -109.3 degrees fareinheit, and is much colder and less messy than regular H20 "wet" ice.

Alloys

An alloy is a combination of two or more elements, and usually have different chracteristics than two elements that it is made up of. 
      
       1.One well known example of an alloy is steel, which is an alloy of iron and another element. 

       2.Bronze, which is an alloy of copper and tin was the first discovered alloy.

5 nteresting facts on Birds

Five Interesting Facts
    1. Changing the color of ambient lights can alter fertility rates and trigger early breeding.
     2.Birds can sense 4 to 5 color wavelength peaks while humans can only sense three peaks.
     3.  birds have a much higher ratio of cones to rods than humans eyes.
     4.birds use their enhanced eyes to find seeds and other foods when flying over a canopy of trees.
    5.Birds can easily spot out the urine and droppings of their prey with their ultraviolet vision.
    6.Birds migrating paterns and breeding patterns are all influenced by the colors that they see in the changing of the seasons.

How are Elements Named?

response to NY Times Article

     When first discovered by scientists, atoms are reffered to by their atomic number (# of protons in the atom).  When given a name by thescientific comitee, they are generally named after famous scientists from the past.  For example, the element Einstienium was named after the famous scientist Albert Einstein.

Chemistry HW 10/2/11

Five Facts:

1. Millipedes are blind and spend most of the day underground.
2. When disturbed they ooze toxic cyanide and other chemicals as a defense mechanism.
3. The only three places where you can see the glow in the dark millipedes are mountain ranges in CA.
4. The millipedes glow is not caused by the same reaction that causes the glow in fireflies.
5. Invertebrate predators tend to aim for the head when attacking their prey.

Scientific Method:  The scientific method, is the process of developing a hypothesis, executing the experiment, and then stating a theory to summarise what was proven in the experiment.  This article followed the scientific method, stating for a hypothesis that the millipedes with the glow in-the-dark gene succesfully manages to protect the millepede from predators.  The article than explained the experiment, which was to lay out fake and real millepedes, with some glowing and some not growing, and see which type survived the best.  The experiment proved that the glowing millepedes did in fact not get attacked as often as the normally colored ones.  This was their conclusion/theory, that the glow in-the-dark gene did help the millepede's to survive.
