What type of energy is present in the batteries of a flashlight? mechanical energy electrical energy chemical energy radiant energy

Electrical energy is the type of energy present in the batteries of a flashlight.

Explanation:

B

Explanation:

Why? Because if you search or look at a inside of a battery you'll see that it is made up of weird chemicals and stuff

(If you actually do look inside of a battery make sure to dispose correctly because it is dangerous.)

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.
