achaaww seriously ? ! tou phir fe(oh)2 kaisay form hua doesnt matter thora sa ya bohat sara bana kaisay thts the big deal . btter understand my argument 2 :roflol:

o bhai jaan, zara Tawajja farmayye .
dekho , you have memorized the test for ions , right ?
us me iron hydroxide bhi hai or calcium hydroxide bhi hai. theek ?
ab iron ka green colour hai and calcium ka white.
Question parh lo zara , us me Fe ions ki conc = 0.450, and Ca ions ki conc. = 0.125
ab kyun k iron ki conc. zyada hai to usi ka colour visible ho ga na considering doosray ( calcium ) ka colour white hai .

han g , kya khayal hai ab ?

its not a noble prize its a NOBEL prize

you should get a NOBEL prize for that!!

yaar apko 50 rupe de dena chahye!! lmao
jk dude

bigger bulb shoul reduce sensitivity.. :/

howw?? it makes it more responsive. besides this is not what i said. i got these questions off the internet somewhere long tym ago so idk. if u think there is something wrong and u r ABSOLUTELY SURE ABT IT then post it here.

LOL c wht i wrote
= The temp of the sample would start to increase and water will be produced due to neutralisation reaction between HNO3 and NaOH and the sample would catch fire when K+ will react with water LOL

 

[MustafaMotani]

Please tell using bigger bulb would reduce responsiveness na.. ??

yes..
thermometer right??

Oh sorry I mixed sensitivity wid responsiveness...

 

[MustafaMotani]

yes..

YEAH

isnt sensitivity and response the same thing??

 

[MustafaMotani]

yara waisay logic tou hay

had hogae

 

[MustafaMotani]

Lol hell no sensitivity is rise of liquid per rise in temperature and responsivenss is how fast thermometer responds to change in temperature
