Need help with this question.

I think it's C.

The peak represents the 2nd heaviest of the options.

THATS WHAT I THOUGHT TOO !!! BS SOLUTIONS SAYS D ! Anyone can explain the answer D?

Got another one for ya'll. Doesn't make sense to me. My answer is D...answer says A.

Got another one for ya'll. Doesn't make sense to me. View attachment 26000 My answer is D...answer says A.

I'm not sure about this one, but I'd assume it's A because of the electrochemical series
K>Ca>Na>Mg... so on until you get to Ag>Au
But that is for the flow of electrons, but that would be for negative flow. The question asks for positive flow, so you just reverse it, therefore silver would have the highest.

but when magnesium is placed in the solution and the other being copper,
Mg is going to oxidise to produce positive Volatage because its more reactive than copper

So i guess maybe the answer
correct me if im wrong

Definitely C.

 

[someth1ng]

For that question, A should be incorrect since it produced a precipitate hence, it will not work effectively

I've never understood "positive voltage" because the voltage depends on how you measure it...

i think the answer is C cuz 1-butanol has the third largest molecular weight and as all molecules used are polar their polarity would not have much difference in the result
