1. The problem statement, all variables and given/known data Here is question in objective form. I have tried answering it but am confused with the answer I got. Instruction: shade A if only IV is correct. Shade B if only I and III are correct. Shade C if only III and IV are correct. Shade D if I, II, III are correct. Shade E if only I, II, III and IV are correct. The question: pitch and asphalt are residual products from the fractional distilation of petroleum. These substances are used as I. protective coatings for road surfaces. II. binding agents for roofing materials. III. organic solvent. IV. catalyst cracking. If this problem is set before you, which of the options lettered A-E will you shade and why? Please explain in detail. 2. Relevant equations No equation is involved. 3. The attempt at a solution I know that pitch and asphalt are residual products from the fractional distilation of coal which can be used for the following: I. protective coating for road surfaces. II. binding agents for roofing materials. III. organic solvents. Because I read that from my chemistry text book. Since I have been reading my chemistry texts book, I have never came across any part where pitch or asphalt is used as a catalyst, talkless of catalyst for cracking or is there any? Judging from my statements above, I choose option I, II and III as correct for the uses of pitch and asphalt and IV not correct for the uses of pitch and asphalt, therefore wrong. The above is my own opinion, anyperson who has a contrary view to my opinion is free to come in let's discuss with the hope of arriving at the correct answer. Thank you as you forward in your replies.
