An example of natural polymer is:
poly(styrene)
poly(chloroethene)
nylon
cellulose
One of the way to carry out hydrolysis in the lab is:
by using water
by using alkaline solution
by using acid
by extraction
Carbohydrates are compounds of:
carbon and hydrogen only
carbon and oxygen only
carbon, hydrogen, oxygen and some other emelents
carbon, hydrogen and oxygen only
An example of complex carbohydrate (polyssacharide) is:
protein
glucose
starch

The identification of the products of the hydrolysis of carbohydrates and proteins can be done using:
(a)
Both carbohydrate and protein monomers are colourless. Originally used for separating coloured substances, chromatography can be used to identify colourless compounds using (a)
This type of reaction is:
condensation polymerisation
addition polymerisation
hydrolysis
cracking of hydrocarbons

heteropolymers
copolymers
homopolymers
