13 i got d, because i think it said 'made from plants' so it has to be cellulose right?

I think this was a very tricky question. Polyethylene can be made from plant material as well!
I picked a because you can't actually make cups from cellulose. But i might just be over thinking this.
I'd still stick to a as an answer tho.

yeah, you might be right

What about paper cup? ain't paper made out of cellulose? Also, for question 17, did anyone put down 1?

 

[petermik]

Well polyethylene can be made from plant material and not from plant material. Cellulose - plant material only...hmm

do you mean a? I put b

so many people put 17 as A.
But the thing is this is not a disassociation. It's just a neutralization reaction to produce salt.

I put down as B. Still believe it's B, but who knows

Yea i was confused at first and put A but then realised it was just a neutralization reaction with equal ratios and all

 

[Hotisgood5]

we're reacting a diprotic acid with a strong base right? i don't see why it's equal ratio : S, please help

I was tossing up between the two, as well

But the question said "used in the manufacture" not "used as a material for the cup"
therefore, cellulose is ALWAYS USED IN THE MANUFACTURE because you obtain the polyethylene FROM cellulose.

So i put D (cellulose polymer). You can have paper/cardboard cups as well which don't use any polyethylene.

monoprotic acid with monoprotic base

lol... i put D, but now I read the question again it's A... =3= fml

What if you get polyethylene from sugars (crushed sugar cane) not cellulose

Acetic is CH3COOH. Monoprotic, unless i chucked a potato somewhere

 

[Hotisgood5]

well fark!! i messed that one up didn't i?!

Well according to Wikipedia,
"paper cups are made from renewable resources (wood chips 95% by weight)"
Wood chips contain wood
Wood contains cellulose
Therefore, is not paper cups made from cellulose then? (i.e. D)

Bro.. It's the BOS. We don't know what they're thinking =3=
But hopefully man, hopefully
