How was paper went of CHEMISTRY 5070/22

[Rida Zahra]

and what was the answer to that mcq that asked---which one will not react. with options zinc hydroxide,zinc carbonate and other.i dont exactly remember the question.

 

[Ram97]

what was the ionic equation in Q.2 in paper2?

H+ + OH- gives you H20

 

[Ram97]

and what was the answer to that mcq that asked---which one will not react. with options zinc hydroxide,zinc carbonate and other.i dont exactly remember the question.

I did nitrate

 

[Ram97]

what was the other ionic eqn Sec B

 

[M.Omar]

answer was "sugars"
i got it wrong :/

:/
Wht abt mcq abt never element Combusting to give incomplete combustion or smthing like tht...I chose CO

 

[M.Omar]

what was the other ionic eqn Sec B

Question part or number..

me too same CO

Last qs about Bromine reacting with Magnesium Astadide

 

[sid2333]

It was so amazing! The theory was simpler! What did you guys have a problem in?

Yeah... theory paper was VERY ESAY. MCQs were also very easy. A.t.p was also esay, other than the last question. Warna the entire paper was AWLAA

Last qs about Bromine reacting with Magnesium Astadide

yeah.. we needed to write the ionic equation:
2At-+Br2=2Br-+At2

 

[sid2333]

yea.. i wrote glucose

answer was "sugars"
i got it wrong :/

 

[sid2333]

yeah.. mine too!

It went good Alhamdolillah.. the best one yet!

 

[Abdul Hanan]

yea.. i wrote glucose

it asked for "class" of the compound not the compound so maybe thats wrong....

 

[sid2333]

it asked for "class" of the compound not the compound so maybe thats wrong....

I wrote it like this:
Simple sugar/ glucose
hope it won't be penalised LOL

 

[Dream.Eater]

I wrote it like this:
Simple sugar/ glucose
hope it won't be penalised LOL

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

 

[sid2333]

H+ + OH- gives you H20

well, if i'm not wrong, are you referring this to the ionic equation which was asked in q2 of theory paper of reaction of calcium hydroxide and acidic solution?
I though the equation was:
Ca(OH)2 + 2H+ = Ca2+ + H2O

 

[sid2333]

and what was the answer to that mcq that asked---which one will not react. with options zinc hydroxide,zinc carbonate and other.i dont exactly remember the question.

Zinc nitrate

I though the equation was:
Ca(OH)2 + 2H+ = Ca2+ + H2O

no you are wrong... the equation was to be of neutralisation that is H+ + OH- =h20

I though the equation was:
Ca(OH)2 + 2H+ = Ca2+ + H2O

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

 

[sid2333]

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