Compound
is a pure substance composed of two or more elements that are chemically combined.
A chemical change, or reaction, happens when
one or more substances are changed into one or more another substances
During a chemical reaction,
new substances form because atoms are rearranged.
In some chemical reactions,
Two or more elements combine to form a compound
In other chemical reactions, a
A compound can be separated into elements or simpler compounds
Just as each element has physical and chemical properties,
Each compound has characteristic properties
Physical properties of compounds include,
Melting point, Boiling point, Density, and color
Chemical properties include,
Changes that occur when compounds are exposed to other chemicals heat or light.
Every compound has a unique set of properties, THIS MEANS
That a compound can be identified by measuring or observing some of its properties.
Some compounds can be broken down into their elements by applying
Heat or using electricity
