Whats chemistry...and can u send me some practice of it..?
Answer:
So it is basically Elements, Chemicals and Molecular stuff. Here is some examples.
EX. H2O - Water.
Which equals 2 parts hydrogen (H) and 1 part oxygen (O).
EX 2. CO2 - Carbon Dioxide
Which equals 1 part Carbon (C) and 2 parts oxygen (O).
To do good in chemistry you must know elements very well like
the symbol AU is Gold and the symbol PB is Lead. Another aspect of Chemistry is the 3 phases of matter.
1. Gas
2. Liquid
3. Solid
That is what it is basically.
Chemistry is something. It is a really interesting course. You will like this course. Areas in Chemistry involve Gas Laws, Rate/reaction mechanisms, Balancing equations, electro-chemistry, thermodynamics, matter/energy... etc. It is a very broad topic that involves a little bit of everything. If you just look up "Chemistry worksheets", you will probably get something, but you could narrow it down a bit. :)
Chemistry unlike Gaul is divided into five principle areas:
Organic - carbon compounds, their synthesis, properties, and applications. Polymers, pharmaceuticals, scrubbing bubbles.
Inorganic - ditto the rest of the Periodic Table. wthout organic carbon (OK - ligands. Everybody needs an organiker.)
Analytical - telling organikers and inorganikers what they got instead of what they wanted. Responsible for quality in this sorry incompetent world.
Physical - thermodynamics, kinetics, the way the world predictively works
Theoretical - quantum mechanics, the fundmanetal basis of how the world is supposed to work.
