    Solving Chemistry Doubts Now :)

    So? Air contains many gases. I suppose that when you would take the average density of all these gases, it falls below the density of CO2 alone. eg.(i am making this up) if the density of CO2 is, take, 10 g/cm3. and the density of nitrogen is 5 g/gm3, so the average density of both these gases...

    I think that when we say "air", everything is included . I mean N2, O2, CO2......etc.

    Hey ,yesterday you had a doubt right? I got the monomers. Protein - NH2-[]-COOH.(All are the same, only difference being the box in the middle would be different.) Nylon- COOH-[]-COOH, and NH2-[|]-NH2.

    Probably you saw this in the MS. However, what readings?

    Another thing, earlier in the question it says that one of the images is diminished, and the question asks us "one" of the images.So, if we make smaller or larger, both are still "one" of the images. [Hope that isn't confusing you]

    I suppose we can make it smaller or bigger. As it's only for 1 mark what's really important is that it should be inverted.

    Somewhat. (There are more intelligent students in my class as well)

    I am sorry. Just realized i entered O levels. I am giving my GCSE's. But, I think that it would most probably be the same.

    Chemistry Doubts: IGCSE Paper 3

    I am sorry i don't know the monomers. However notice here that in the protein, there is NH and CO on either side of all kinds of boxes.-NH-[]-CO- In nylon there are 2 types of boxes, one having CO on either side and the other having NH on either side.(-NH-[]-CO-)and(-CO-[]-CO-)

    I think there is a -1 for each wrong (extra) choice.

    Chemistry Doubts: IGCSE Paper 3

    Nope it's different. Protien - NH-[|]-CO-,NH-[]-CO-. Nylon- CO-[|]-CO-, -NH-[]-NH-. Hope you understand.

    Can you give an example of a question.

    Chemistry Doubts: IGCSE Paper 3

    Draw the structure of nylon, since it has the same amide linkage. -CO-[]-CO-NH-[|]-NH-CO-[]-CO- [] is one box, [|] is a another box.
