Do yourself a favor...and walk into a room!

After the light bounces off of the walls, the chair, the lamp, the coffee table, or your mound of dirty clothes, enters your pupils, reacts with chemicals in your head to create an image, instead of analyzing that image macroscopically,
view it microscopically.
That chair is a solid. Its atoms are close together, vibrating and humming away in harmony. Some solids are crystalline, which means that they are in very specific atomic arrangements.
Crystalline solids, like diamonds, and other other hard rocks (particularly crystals) have very neat atomic arrangements.
While amorphous solids, like coal, have very random atomic arrangements. These solids tend to be softer.
Now, I know I forgot to mention this, but that cup of water the you waked into the room with, (while the cup itself is indeed a solid) the contents (good old H2O) is a liquid.

Solids become liquids when they reach their melting point.
The atoms in liquids are much farther apart and move around more more. Liquids have no predefined shape and generally take on the shape of their containers. When you heat a liquid to its boiling point it becomes a gas.
The gaseous form of water is steam. Gas has no definite shape nor a definite volume. The particles in gases move relatively independent of each other. This is evident when you spray your mom's favorite perfume, most likely White Diamonds, and its smell slowly disappears into the air. The atoms in gases move very freely of each other, unlike those in liquids and solids.

Most matter goes through the phase solid->liquid->gas [H2O(s)->H2O(l)->H2O(g)]. Some matter, like carbon dioxide, goes through sublimation. Which is Solid->Gas [CO2(s)->CO2(g)]. Think dry ice. The opposite of sublimation is deposition.

But indeed, what is matter? Literally anything that has mass and occupies space.

Matter could either be:

Pure Substances, an Element (one type of atom throughout) or a compound (two or more elements in a very specific ratio in the molecular makeup, ex. H2O there will always be one hydrogen atom to every two Oxygen atoms).
Compounds are more difficult to seperate

Mixtures, which are just a mix of different pure substances. Like coffee with creamer, or kool-aid. You can still very simply separate or recognize the sugar from the kool-aid in the substance.

Mixtures can either be homogenous: which means they are generally the same throughout the mixture. Or they can be heterogenous, which means it varies from position to position.

So, remember, here are words that you absolutely have to re

Hey, guess what!?!


We have chemistry, together!

Welcome to my brand new blog, We Have Chemistry! Long story short, I am just a young Biology Major on a Pre-Med track. I decided that the best way to learn and retain information is to teach it! I also realized that many students have problems with Chemistry and it is given to potential science majors early on to weed out the 'baddies' from the 'goodies'. I wanted to create a place that we could all come together, and be Goodies!

In this blog we will discuss and learn Chem in detail. I will start from the nature of general chemistry, and then advance on through Bio and Organic Chemistry.

I urge readers of this blog to comment and influence the content. If you have any article, for video, or work you would like to be posted, please e-mail it to me.

Until Next Time,
Chemists, Charge!
