This is divided into two areas: organic and inorganic chemistry
What is chemistry
100
Anything that occupies space and has physical and chemical properties
What is matter
100
All matter exists in one of three different physical forms: solid, liquid, or
What is gas...Phew :)
100
This is a result of a chemical reaction; combinations of two or more atoms
of different elements united chemically with fi xed chemical composition, defi nite
proportions, and distinct properties; example:
What is a chemical compound
200
The study of substances containing carbon
What is organic
200
basic materials of all matter
What is elements
200
This has volume but no defi nite shape
What is liquid
200
There are four classifications of compounds
What are oxides, bases, acids and salts
300
study of substances that do not contain carbon but may contain hydrogen
What is inorganic chemistry
300
Cannot be separated into simpler substances
What is chemical means
300
example of a gas, with no volume or shape
What is steam
300
compounds of any element combined with oxygen
What is oxide
400
Most of these substances will not burn
What is inorganic
400
the basic building blocks of all matter
What is an atom
400
Does not form a new substance; no chemical reactions or new
What is physical change
400
compounds of hydrogen, a non-metal such as nitrogen, and sometimes oxygen
What is an acid
500
All living things made of .
What is carbon compounds
500
formed by chemically joining two or more atoms; types:
What is a molecule
500
occurs with change in the chemical composition of a substance
