What is the kindest thing you have ever done? I played basketball with a girl from my old school who was in special education, she couldn't make friends easily so once a week I would play basketball with her!

The kindest thing I've ever done is give 200 dollars to a homeless person whom I saw every day, with her dog ad child, and I could tell she wasn't faking and that she wasn't a drugged up person so I decided to give her 200 dollars

Explanation:

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.
