All matter is composed of molecules. Molecules are composed of
which consist of a nucleus surrounded by a
cloud of electrons. The nucleus
is composed of protons and neutrons, which are themselves composed of quarks.

Matter can be changed or combined in different ways,
Fact: Mixtures and solutions can be separated.
Physical mixture - in which the molecules
remain unchanged but are moved around to form mixtures, solutions,
and colloids (for example, water and salt form salty water and molecules
of nitrogen, oxygen and other gases form

Air is a mixture!
Water is the product of a chemical reaction!
reactions - which the atoms to form different molecules
(for example, molecules of gaseous hydrogen can
be combined with molecules of gaseous oxygen to form liquid water)
A chemical reaction occurs when two or more chemical substances are
mixed together. This means that the atoms that were joined together in
the original substances
break apart and rearrange themselves to make a new substance, one or
more substances may be transformed into one or more new
substances. This new substance is quite different from the original

Some products of chemical reactions are heat, light, sound and changes
Chemical reactions are classified according to the kind of change that
Examples of Chemical Reactions:
A sparkler contains magnesium. This, when lit, reacts with oxygen in the
air and produces light and heat.
The chemicals inside a rocket, when lit, react with the oxygen in the
air and produce heat, light and sound.
