Which of the following best identifies a benefit of using renewable energy sources rather than nonrenewable energy sources? А
Renewable energy sources do not have negative environmental impacts, whereas nonrenewable energy sources have many negative
environmental impacts.
B
Renewable energy sources are replenishable and are virtually inexhaustible by human consumption, whereas nonrenewable sources do
not form in a short period of time.
Renewable energy sources are available uniformly throughout the world, whereas nonrenewable sources are unequally distributed.
D) Renewable energy technologies are more developed and more readily available than nonrenewable energy technolo

a chemical reaction

explanation:

the electrical  conductivity  of asolution  of an electrolyte is measured by determining the resistance of thesolution  between two flat or cylindrical electrodes separated by a fixed distance.

lol for the pointsss

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.
