Condensed structural formulae of alcohols and reactions of alcohols

Draw the condensed structural formula of and name the major product of each of the following reactions.

There are four reactions that need to be solved....
A.) CH3-CH2-CH2-OH yields ? Catalyst is H2SO4 and is 140 degrees celcius
B.) CH3-CH2-CH2-OH yeilds ? Catalyst is H2SO4 and is 180 degrees celcius
C.) CH3-CH2-CH2-OH yields ? catalyst is K2Cr2O7
D.) CH3-CH2-CH2-SH yields ? catalyst is K2CrO7

If anyone could help me that would be greatly appreciated!!! THANKS  :)

Sulfuric acid and heat will give an elimination

Cr2O72- is dichromate and is a strong oxidizing agent.
