Free Response Question - PLEASE HEL 5880 grams of paraffin wax, C25H52 are burned in excess oxygen at 520 C in a rigid 150 Liter container according to the following equation:
C25H52 + O2(g) --> CO2(g) + H2O(g)

a) Balance the equation
b) Calculate the pressure of carbon dioxide gas when the reaction goes to completion
c) Calculate the pressure of water vapor when the reaction goes to completion
d) If there are 18.55 moles of oxygen gas leftover in the container along with the carbon dioxide and water vapor when the reaction goes to completion, what is the total pressure of the system?
e) The rigid container is opened, explain which gas is going to effuse faster, water vapor or oxygen gas? Prove mathematically how much faster.

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.
