How was paper went of CHEMISTRY 5070/22

[Laibaaa]

It can be correct because it belongs to the similar class i guess

I wrote starch :/ is that correct?

 

[sid2333]

my dear this sort of neutralisation is only possible when both the reactants are in aqueous solutions. Was CALCIUM HYDROXIDE IN AQUEOUS SOLUTION? NO! IT WASN'T. So it is incorrect!!

its a neutralisation so its H+ + OH- = H2O
caoh is somewhat soluble since its solution is limewater afterall.....

its a neutralisation so its H+ + OH- = H2O

i wrote
"monosaccharide such as glucose"
is that corrrect????

Omg! ME TOO!!

 

[sid2333]

No. It's incorrect. Starch itself is a carbohydrate. Question referred to the hydrolysis of carbohydrate. So it was simple sugar.

Any neutralisation reaction has the equation H+ + OH- = H2O
Thats the basic neutralisation reaction which they asked for

Omg! ME TOO!!

great minds think alike...

AN ACID BASE REACTION IS ALWAYS NEUTRALISATION SO THEREFORE IT IS H+ + OH- =H2O

bro it didnt ask for the equation above it asked for simple the neutralisation ionic equation which is H+ +OH- =h2o

haha or a counter argument may be "fools seldom differ" The results will decide

Insha Allah we will all get good results!

 

[rammy97]

H+ + OH- =H20!! #TeamNeutralisation

 

[Dream.Eater]

H+ + OH- =H20!! #TeamNeutralisation

Sid233 stop acting like a jerk..u're not the only one to answer right questions -_-

Umm, Well in the hydrolysis of carbohydrate, I wrote Alcohol, though it might seem stupid, but I searched the net and saw that hydrolysis of starch forms alcohol which is also a carbohydrate. :I
Dude what was the answer of the that percentage yield second part?

i got 62.9%

 

[Proud otaku]

i got 62.9%

hmm, Dammit I got 50 %
What were your values, I mean who did you get that answer?

 

[asadalam]

2.93(given in q)/4.66(given above) X 100

Percentage yield is actual yield/theoretical yield

 

[Proud otaku]

2.93(given in q)/4.66(given above) X 100

Percentage yield is actual yield/theoretical yield

Hmm, I wrote the same values, then why did I get 50? hmm, well atleast I'll get something for the correct procedure right? XD
