Balance the redox reaction equation (occurring in acidic solution) and choose the correct coefficients for each reactant and product. __mno4−(aq)+ag(s)+h+(aq)→mn2+(aq)+a g+(aq)+__h2o(l)

Explanation:

A balanced redox chemical equation is an equation that contains same number of atoms on both reactant and product side. Also, it contains same total charge on reactant and product side.

For example,

Number of atoms on reactant side are as follows.

Mn = 1

O = 4

Ag = 1

H = 1

Number of atoms on product side are as follows.

Mn = 1

O = 1

Ag = 1

H = 2

Therefore, to balance the equation multiply on reactant side by 8 and multiply on product side by 4.

Now, total charge on reactant side is +7 but total charge on product side is +2. Therefore, to balance the charges we multiply Ag(s) on reactant side by 5 and on product side by 5.

Therefore, completely balanced redox reaction equation will be as follows.

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.
