I wrote since 1 mole of the Al compound was reacted with 2 moles of acid to form 1 mole of the product..since there is and extra mole of acid left to use, we can show that the acid was added in excess..it makes sense..dunno if its correct though.oh and omg what did you guys write for how to show that excesss was addedddd ?
It does effect the no. of moleserr no, the question asked for temperature change and not enthalpy change and temperature change doesn't change if you increase the volume as long as its the same concentration
less energy is released since electron affinity is an exothermic processincreases cuz there is more shielding and more repulsion. Also the force of attraction from the nucleus is less so more energy is needed to add the electron. Thats what i think as i did not know we had affinity x.x
Yeah i get it..If thats the case i am so screwed..lol..but how can u practically show it? i mean u can show that the solution is still acidic by using a pH meter. lol i don;t know any other way.You do make sense but I think the question asked on the practical procedure and not calculation method , I hope you know what I mean
Smaller hydrocarbons are more useful, and smaller hydrocarbons are easier to make products with...i know..the 2nd one doesnt make sense..lol..I know I hated that question so so much , I wrote some stupid crap that made no sense at all -.- what did you write for the importance of cracking process in the industries ?
It does effect the no. of moles
only the first electron affinity is exothermic the rest are endothermicYou had to write that
less energy is released since electron affinity is an exothermic process
check the link I thnk u r ryt..I wrote 1/5How can it not effect the temperature if its effecting the enthalpy change , they are all related
Yes haha thanks alot for the link , I guess it explains my theory pretty wellcheck the link I thnk u r ryt..I wrote 1/5
Yes exactly and the question was talking about the first electron affinitiesonly the first electron affinity is exothermic the rest are endothermic
U jus put a smile on my face. lol...
I guess giantokay so since that one is figured what else was there ? I actually liked the MCQ oh was phophorus a giant atomic structure or a small molecular ?
2nd time u made me smile...hahahaha! xD I guessed that one..lolI guess giant
For almost 10 years, the site XtremePapers has been trying very hard to serve its users.
However, we are now struggling to cover its operational costs due to unforeseen circumstances. If we helped you in any way, kindly contribute and be the part of this effort. No act of kindness, no matter how small, is ever wasted.
