The molar heat capacity cp, mof is described by the following equation over the range : + 1.035 * 10-9 t3 k3 cp, m r = 3.093 + 6.967 * 10-3 t k - 45.81 * 10-7 t2 k2 300 k 6 t 6 1700 k so2(g) (0cv> 0v)t k = -1> v (0v> 0p)t in this equation, t is the absolute temperature in kelvin. the ratios tn/kn ensure that cp, m has the correct dimension. assuming ideal gas behavior, calculate q, , , and if 1.50 moles of is heated from 22.5°c to 1140.°c at a constant pressure of 1 bar. explain the sign of .

i'm pretty sure it is letter c.) car

so she was walking and she stepped on warm jeffy , uh uh uhh dadye i just pooped my pants

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.
