The chemist claims that a new substance is formed when Substances A and B are mixed.
Which three observations support the claim?
O A Bubbles are produced.
B
There is a temperature change.
O c. The substances can easily be separated again.
OD. The product has properties of Substances A and B.
O E. The mass of the product is not equal to the sum of the masses of Substances A and B.

i believe it is 40–40–20%

explanation:

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.
