Title: Help with Test Prep Post by: mz24k on Aug 14, 2011 These are pre test questions I am very bad with chemistery apparently *laughs* So I have been on here as much as possible and see that Lena and I are at the same school taking the same classes. Lena if you need help with ' Mediolegal Inv. into Death" let me know, although I had that class months ago, and see that your done with your chem class, thats where I am now ;-)
So these are pre test questions, anyone that can help and maybe give page number where to look I would appreciate it much :) Here they are: Which is a characteristic of alkanes? contain C = C general formula CnH2n saturated some isomers are cis and trans _____________________________ ___________ Which fossil fuel, when combusted, emits minimal amounts of carbon monoxide, hydrocarbons, and particulates? In other words, which of these burns the "cleanest"? petroleum charcoal natural gas coal _____________________________ ___________ At current usage rates, world reserves of which fuel below are estimated to last for the least number of years? natural gas hydrogen petroleum coal _____________________________ ___________ A compound containing seven carbon atoms is heptane octane hexane nonane _____________________________ ___________ The complete combustion of C8H18 yields NOTE: The "8" and "18" are intended to be subscripts. The "2"'s are subscripts in the answer choices below. C2H2 and H2 CO and H2O CO2 and H2O C and H2 _____________________________ ___________ An organic compound with an OH functional group is a(n) aldehyde ketone ether alcohol _____________________________ ___________ The odor in many fruits is due to the presence of amines esters carboxylic acids alcohols _____________________________ ___________ Which polymer occurs naturally? nylon dacron polycarbonates latex rubber _____________________________ ___________ Polysytrene is a plastic that is noted for its use in plumbing pipes drinking cups clothing fabrics automobile paints _____________________________ ___________ Which carboxylic acid is known as vinegar? butyric propionic acetic formic Thanks for any help I have some of these answered, but mine may be wrong. Theres no rush, and thanks for any help, Mz24k Title: Re: Help with Test Prep Post by: mz24k on Aug 14, 2011 Module 4 Homework
