It was decided to analyze a waste solution that contains an unknown concentration of Mn2 ions using colorimetry. A strong oxidizing agent was added to a 6.20 mL sample of the solution to convert the colorless manganese ions into purple permanganate ions. After the reaction is complete, the solution was diluted to 100.0 mL and analyzed in a colorimeter. The percent transmittance of the solution was determined to be 45.6 %. Also a calibration curve was prepared by using a series of solutions with known concentrations of permanganate and the equation for the best fit line was found. y= 1.10x103 x + 0.026
1. What is the absorbance of the permanganate in the diluted waste solution?
2. What is the concentration of the permanganate in the diluted waste solution?
3. What is the concentration of the Mn2 ions in the original waste solution?

u i forgot the answer?

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.
