Ask Custom Question

Hello,
I was wondering whether you would be able to complete my chemistry assignment that I have received. I have attached the task sheet, scaffolding for refuting the statement and scaffolding for supporting the statement (depending on which one you choose). The due date for this assignment is this Friday so I would prefer to have it before then. Also, my teacher said you don't really need to fully follow the scaffolding; it is purely there as a guide.

I would really love to get an A on this assignment; so please make sure it is good :) (and in the word limit!)

Due to the fact that nobody has signed out on doing this task, I just thought I should attach my assignment that I have completed and the scanned through feedback that my teacher send me. PLEASE HELP ME GET AN A!!!

  • "Thankyou for the feedback. I have a few question though; With the first statistic about cost below... “According to Sigma-Aldrich catalog, cost of 1L octane is AUD $ 392.00, whereas the cost of 1L ethanol is AUD $196.00. Moreover, if ethanol is obtained from sugar industry as a by-product, it may cost even less. Source of oxygen is ambient atmosphere, so it costs nothing. So ethanol is much cheaper than petrol, in fact it is half-priced: AUD $ (392-196) = $ 196.” I didn't think it made sense because the cost of petrol per litre is normally a dollar something or even less than a dollar not a couple of hundred of dollars. For example, a statistic that I found in america was: "U.S. ethanol production costs are about $1.20 per gallon of ethanol, or $1.82 per gallon on a gasoline-equivalent basis." However, I was wondering whether you could find an Australian statistic. Also, you mentioned that H20 is not a greenhouse gas. However, in the combustion equations it is actually carbon dioxide and water vapour which are produced and they are both greenhouse gases. Finally, how do I calculate the energy efficiency of ethanol and petrol? "
