Answer:
80g=0.08kg
20cm=0.02m
density=m/v
= 0.08/0.02
=4kg/m^3
it is less than density of water so it floats
When two compounds have same molecular formula but different structural formula, they are said to be
isomers of each other and this phenomenon is called as
isomerism.
Hexane has
six isomers.
The isomers of hexane have a difference in their structure due to parent chain length (
chain isomerism). They are also differentiated on the basis of straight chain as in n-hexane and branched chain as in remaining five. Structures along with names are shown below.
B) They worries people would destroy the animals and land.
