One method for determining the concentration of hydrogen peroxide in solution is through a redox titration with potassium permanganate under acidic conditions. in this procedure the hydrogen peroxide reduces the permanganate ion. a. what is the oxidation number of the mn ion in the potassium permanganate? 3. b. write the balanced half reaction for permanganate ion to form mn2* in the acidic solution. c. write the balanced half reaction for hydrogen peroxide in the acidic solution in which oxygen gas is released. d. write the balanced complete reaction. e. in a titration of a 100.0-ml hydrogen peroxide solution, the analyte turned a faint pink after the addition of 3.56 ml of a 0.30 m potassium permanganate solution what is the concentration of the hydrogen peroxide in the solution?

the answer is barium and copper bromide

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.
