how was chemistry p42?

[DumbIdiot]

as far i remember, 0.03 mol of naoh was added to 0.5 mol of acid.

but since yo guys are saying they had the same number of dp, i guess i messed up.

 

[Cesar_malik]

No thats other part and yes it would form salt but basicslly the polymer form was additiin

 

[Cesar_malik]

Buffer composed of weak acid or base with its strong salt both in large reservoirs so tht should do it but just to let u know I messed a little and dont remmb this quest very well

 

[BITTUDROCKSTAR]

but the qstn said when k was mixed with naoh so should not that form a ester link?

Ester is formed when acid reacts with an alcohol. NaOH is a base. The result would be a salt (COO-Na+).

What is the ph of buffer solution and the ph asked above that que?

shit i just didnt thougth of it i just cooh and oh groups coming together...and here goes my 5/6 more ..hope gt is really otherwise i am doomed

what answer did you get

i got 3.68 using (0.03 nah and 0.5 acid)
but if it was actually 0.3 naoh in 0.5acid then you would get 5.05

 

[Ujjwal Basnet]

What is the ph of buffer solution and the ph asked above that que?

i got around 4.6 or 4.7

 

[Cesar_malik]

i got around 4.6 or 4.7

i think i got the same coz i used 0.3 and 0.5
all messed up lol

 

[Ujjwal Basnet]

i think i got the same coz i used 0.3 and 0.5
all messed up lol

at least i got smthng right

 

[Cesar_malik]

well i dont know this is right or wrong its all luck now
still not sure if it was 0.3 or 0.03 lol
please someone confirm

What were the enthalpy changes?

 

[Ujjwal Basnet]

What were the enthalpy changes?

well i dont remeber exactly but it was around -23 for cl and +111 for I

 

[urvi kapoor]

Yes same! And what did you write for the source of no3- and phosphate?

 

[Ujjwal Basnet]

Yes same! And what did you write for the source of no3- and phosphate?

well i wrote fertillizers for nitrate and dead bodies of animalsfor phosphate

 

[Dolly96]

I wrote acid rain fr phosphate cn it b write?

 

[Dolly96]

Right*

 

[urvi kapoor]

I wrote acid rain for nitrate.. And fertilizers for phosphate

 

[urvi kapoor]

And what were the interactions between the tripeptide?

 

[Dolly96]

Y is it difficult to remove nitrate ions?
