you can observe chemical reactions from its smell, colour, shape, or the change in it's properties
physical (because you can observe it without inducing a chemical reaction).
Burning of metals in fireworks is a chemical reaction and is what makes the fireworks glow with different colors.
a precipitate is a solid that forms during a chemical reactions
It depends on the chemical reaction. For example when you burn something it is a chemical reaction, but that is way different than if you mix baking soda and vinegar which is also a chemical reaction. It changes the matter into a different chemical matter make up of that substance.
Volume is a physical property.
The way I remember the difference, is: a physical property is a property that you can observe without changing it (or observe without a chemical reaction). So properties like melting point, boiling point, density, color, hardness are all physical properties. A property like 'reacts with water' could only be observed by performing the reaction to observe the change.

a chemical property can be observe when under going a chemical reaction some examples are rusting reactivity wood acid metal water and hydrogen
A chemical reaction
The chemical or chemicals formed in a chemical reaction are called the product of the chemical reaction.
Its a chemical reaction.
