Answer:
Sugar dissolves faster in hot water than it does in cold water because hot water has more energy than cold water. When water is heated, the molecules gain energy and, thus, move faster. As they move faster, they come into contact with the sugar more often, causing it to dissolve faster.
A homologous series may be defined as a family of organic compounds having the same functional group, and the successive(adjacent) members of which differ by a CH
2
unit or 14 mass units.
Two consecutive members of homologous series of Aldehydes: CH
3
CHO and C

CHO
A carbon compound is made up of two parts: R−F, where R is the hydrocarbon part and F is the functional group part.
So, this R (hydrocarbon) part determines the physical properties of a compound and the F (functional group) part determines the chemical properties of the compounds.
Actually, the ionic equation for this is a reversible
equation since codeine is a weak base. Any weak base or weak acids do not
completely dissociate which makes them a reversible process. The ionic equation
for this case is:

C18H21O3NH+ + H2O
