So how was chemistry P12 today?

[Kamihus]

Ohh that one ya it was A

And the mass when NaClO was formed, 18 something?
In organic 38 structure would not react with bromine
39 will the reaction with Br2 be redox?
and 40 all would make ethanoic acid

I rmr 39 was B
And yea for 38 yeah it won't but where did NACLO come from and remind me what 40 was?

 

[Kamihus]

there was something like cold and in it NaClO would be formed and we had to calculate its mass.
40 was which of these is ethanoic or propanoic acid it was like ethanol or propanol an aldehyde and a nitrile

 

[Snowysangel]

The Kp one yes it was 5.37 or something like that.
Couldnt do the bond energy and wrote 351

Was the partial pressure of steam the same as CO's?

 

[Kamihus]

Was the partial pressure of steam the same as CO's?

If they were on the same side of the equation then yes...

 

[Kamihus]

And one repeated question with 0.1 mol dm^-3 hydrogen peroxide as the ans

 

[Snowysangel]

What about the first in section B, the viscous one? A or B?
Ammonia one was D as it did not react as a base?

What was the viscous one?

 

[Afzal1]

What was the viscous one?

its A rite

 

[Kamihus]

What was the viscous one?

I did A but I have no idea what is correct. It was either A or B

 

[Snowysangel]

I did A but I have no idea what is correct. It was either A or B

I mean what was the question lol

 

[Kamihus]

Organic question section A what would be converted to carboxylic acid, butanal or 2-methyl butanal?
PVC one ethene would not be formed?
Elimination of halogenalkane was C two products could be formed?

 

[Afzal1]

I did A but I have no idea what is correct. It was either A or B

im pretty sure it is A

 

[Kamihus]

I mean what was the question lol

One had hydrogen bonding other had van-der Waals forces so would the hydrogen bond one be more viscous
That was the last statement

 

[Afzal1]

One had hydrogen bonding other had van-der Waals forces so would the hydrogen bond one be more viscous
That was the last statement

ya see because water has hyderogen bond and the txt book says it is vry viscous so since they didnt specify anything about P so it is correct

 

[Kamihus]

First one was C peak would be lower and no effect on activation energy
second also C states of matter giant ionic simple molecular question
another simple one in which sodium ethanoate would be formed in the hydrolysis

 

[Snowysangel]

That was the last statement

Ohh. Would it? It said that they had the same mr so I didn't think so

 

[Afzal1]

PVC one ethene would not be formed?
Elimination of halogenalkane was C two products could be formed?

i think butanal

First one was C peak would be lower and no effect on activation energy
second also C states of matter giant ionic simple molecular question
another simple one in which sodium ethanoate would be formed in the hydrolysis

ya correct

 

[Kamihus]

Ohh. Would it? It said that they had the same mr so I didn't think so

The Mr was same but yeah the text book does say viscosity increases with hydrogen bonding so probably A

 

[Omar Haider]

What did you guys put for the Ag+ and Nh3 question? I put A (all three options) and for the PVC one I put the bacteria and fungi option.

 

[Afzal1]

ya correct...
