Isn't it KOH not KHO? Hydroxide is OH-

Yes it is KOH, sorry

 

[Ned22]

Also there was one question I had no idea on, the question about the word to describe the water on the earth and in the atmosphere or something. Anyone willing to tell me what it was?

It was hydrosphere That was a really confusing question

I swear when I did the corrosion experiment, the nails in water were rustier than the nails in the salt water. & my teacher didn't even say anything when I handed in the report of it. Stupid contamination 8(

does anyone know which circuit was the parallel one? That one totally thew me because of the position of the ammeter. I put D but now im thinking it was A...

oh yeah that question .. i hate physics haha.

 

[sam57]

type in potassium hydroxide to google and it says KOH

 

[RealiseNothing]

It was KOH, and the parallel circuit one was D.

ARGHH SH*T there goes 1 mark....

ARGHH SH*T there goes 1 mark....

I lost at least 6 marks or so, so far... xD

was it the salt water to just water that would make the nail corrode faster?

Yes, salt water makes iron corrode faster.

6 marks + (considering full marks on writing ?)

I hope for 85+, I'm hoping for near 100% in the short answers and extended combined!

isn't iron oxide = rust? Shouldn't it be just the oxygen?

 

[RivalryofTroll]

isn't iron oxide = rust? Shouldn't it be just the oxygen?

Everyone says that it was D, I put C xD

 

[lath]

Everyone says that it was D, I put C xD

what was C and D?

 

[Queenroot]

So am I !

worst: 80
best: 90

 

[Blurgh]

isn't iron oxide = rust? Shouldn't it be just the oxygen?

Question asked which would rust the fastest. I put D, which was the salt water.

 

[Lina3]

what was C and D?

The parallel circuit question. I am pretty sure it was D, because Ammeters are always connected in series.

what was the question where there was a yellow solid formed from 2 clear solutions? i guessed neutralization. :S

I guessed neutralisation too. I think it was precipitate though.
