    Organic chemistry help

    a) Condensation reaction, similar to esterification, but instead of a ester link, there will be a amide link b) esterification reaction, the name of the ester will have the alcohol with suffix -yl first followed by the acid with a suffix of -oate. In this case, you name the alcohol first...

    Calculus in pphysics ???

    pre sure you can, but if u make a single error then you dont get any mark for it. But no point really in using calculus. Anything u can do with calculus, is much easier using the formulas. Just plug and chug

    chemistry or physics

    Look into the course forboth yr 11 and 12 for chem and phys, and choose which one seems more interesting. Don't worry bout how others r doing with it, if they are doing bad, high chance that they find it boring. So choose which one has more interesting content

    _ _ _ _ _ _ _ _. 8 seats to sit on. Mariya must be in seat 1 and Aofa can't be in seat 8, so for now we will put her on the second seat: M A _ _ _ _ _ _. Then you got the 3 ppl that gotta be together so : M A c m h _ _ _ _. For those 3 ppl, they have 4 patterns in which they can sit, and they...

    11 UNITS!?

    lmao exact same subjects as me. 3 sciences isn't hard and if u like maths then 3u will be ez, but you do gotta put a lot of effort into the subjects if you want to do good.

    Oxidation and Reduction (Chem)

    Ah yeh, didn't realise what I was saying, even when I stated that oxidation is losing lol. Thanks for pointing it out!

    Oxidation and Reduction (Chem)

    OILRIG: Oxidatoin Is Losing, Reduction is Gaining. Simple terms, if electron is on RHS, its an oxidation reaction, if its on LHS its a reduction. ie Cu_{(s)}\rightarrow Cu^{2+}_{(aq)} + 2e^- is an oxidation reactoin cos the copper is loosing of an electron. The reverse of this would be a...

    Molarity and Concentration

    n=cv (In datasheet so no need to worry about remembering). Thats probably the most important formula in molarity. You also have the c1v1=c2v2, but this is only used in dilution. You also have the other measurements of concentration like w/w%, v/w%, ppm and like 2 more I think, but they are just...

    how do you find the maximum distance of a trajectory?

    easiest thing to do is to draw a rough sketch of the graph. Then you can easily find the max distance with a given time. For a) you can imagine that you're restricting the domain so that its only from -infity to 6 (As it asks for the first 6 seconds). then you just need to find when it is the...

    Combination Qs Help:)

    1. Expanding the combination you get : \frac{n!}{7!(n-7)!} + \frac{n!}{8!(n-8)!} You can expand the denominator of the second fraction so you get 7!(n-7)! and then just do basic arithmetic and solve for n

    Permutation Questions Help

    Ill add on: 1. Total is 7!/2! cos of the repeating S. Then the number of ways where the S's are at the end : 5! x 2!/2!. So the probablity, if I didn't do any mistakes should be (5! x 2!/2!)/(7!/2!) 4. Think the question is trying to make itself seem tricky by adding the 720 ways and if they...

    Trig help

    Another way, convert tan theta into sin/cos. Then just multiply and eventually you'll get the equation sin^2(\theta)-3cos^2(\theta)+2sin(\theta)cos(\theta)=0. Factorising it will give you (sin(\theta)-cos(\theta))(sin(\theta)+3cos(\theta)). Solve for both equations and you get your answer
