Astudent did a simple and fractional distillation on a mixture of a and b. their starting mixture was 46.17% a. the first fraction of their simple distillation was 39.08% a and the first fraction of their fractional distillation was 10.78% a. how many theoretical plates did they have in their fractional distillation? type your numerical answer rounded to the 2nd decimal place (n. nn).

- decrease the number of plants and animals living in the water.

the answer is barium and copper bromide

hydrocarbons are organic compounds that contain only hydrogens and carbons. they can be saturated (those which contain only carbon-carbon single bonds) or unsaturated (those which contain carbon-carbon double or triple bonds) in nature. hydrocarbons can undergo several reactions like substitution, elimination etc.  

on substituting one or more hydrogen atoms in hydrocarbon it results in the formation of haloalkane. as the halogen atoms are large compared to the carbon and hydrogen atoms, due to which the molecular weight increases and the bond become polar because of presence electronegative halogen atom and results in the increase in boiling point of the haloalkane.

thus, the correct option is (b) that is the boiling point of the new compound increases on substituting a hydrogen atom with a halogen in a hydrocarbon.

i believe the answer is 5,000
