Value of 'x' in acid formula?

[Syed Ali]

What was the value of x and what we had to suggest in the next part?

 

[Angraiz]

x=2. Acid could've been H2SO4 or H2CO3.

 

[Syed Ali]

thanks! I wrote the same

This question took 3 minutes to answer though, but I also wrote x=2. And the acid was sulfuric acid.

Dude, these redspots really suck. Don't every try to learn their answers. :|

 

[sarah rasool]

zinc su;phate is the colourless solution!!!!!Cu was the correct ans!!!!

 

[habib123]

yea i know i was dumb enough to not read the question carefully shit

m m for dat acid thingy cant we just write da formula h2A.......is it wrong ??? i even made sa equation wd da same formula.......????! is h2A sume acid??!

No, you won't get any marks for them. Cuz you'd to SUGGEST a typical acid with that kind of formula.

 

[sahar]

but i solved da same kinda question in redspot n dat wax da answer

 

[habib123]

not really h2so4 was the right answer and h2A is the formula we had to see what a was it was so4

 

[sahar]

any wht abt da equation ?? i made it wd h2a is dat even wrong ??

 

[habib123]

it sure. i wrote the same thing as u and dont ever study or solve redspot there are alot of wrong answers

 

[Zishi]

any wht abt da equation ?? i made it wd h2a is dat even wrong ??

Yep! That's wrong, too.

 

[sahar]

oh nO.....i wax so damn confident abt dat questiOns

The second part will surely be marked as correct . It will be given the error carried forward mark
