General paper discussion

[Snowysangel]

I think it was ag(+1) + cl(-1) = AgCl

 

[farhan141]

I wrote the same.

I think it was ag(+1) + cl(-1) = AgCl

i wrote the same too

 

[ijlalm]

i wrote the same too

you had to write the state symbols too as the question demanded it.

 

[Kamihus]

I think it was ag(+1) + cl(-1) = AgCl

is it alright if i wrote cl- first and ag+ after
the states were aqueous for both the reactants and solid for the product

Yes it doesn't matter, it's correct both ways. I wrote exactly the same . This is the first time that I got an ionic equation correct

yeah i wrote them too

I attempted all odd-numbered questions... 1 3 5 7...

same here

 

[Nouman1997]

What were the 2 ions in the Vanadium formula question

 

[Nouman1997]

in sec B

I think the ratio of AgCl and Na was of 1 is to 1 so i calaculated the moles of Na and them multiplied it with the mass of Na

 

[fatima0000]

what was the energy in kJ?

[fatima0000]

What were the 2 ions in the Vanadium formula question

do tag me when you get the answer

 

[Saad Mughal]

The two Ions were:
- Ammonium ion, NH4 +.
- Metavanadate ion, VO3 -.

 

[fatima0000]

Shayad 5400

but mine was 4200 kj

 

[fatima0000]

The two Ions were:
- Ammonium ion, NH4 +.
- Metavanadate ion, VO3 -.

and what was the formula from which it is obtained?

and what was the formula from which it is obtained?

H4NO3V.
