A concentrated solution of nitric acid (HNO3) with a concentration of 2.0 M is used to neutralize a 17.1 g sample of barium hydroxide (molar mass is 171 g/mol). The unbalanced equation representing this reaction is below.

HNO3 + Ba(OH)2 á Ba(NO3)2 + H2O

What volume of nitric acid was used to react completely with the sample of barium hydroxide?

the earth would become to overheated and everything alive on it will eventually die from overheating. plants will eventually die as well, water will evaporate, and it will be nothing but a hot planet without anything living on it.

it would be a gas formation

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.
