Aa gai aqal?
Bat kis ki ho rahi hai? -.-
u just said hydrolysis sire

I have the concepts of organic well!! U mentioned esters hydrolysis in naoh presence just which means dat the reaction will produce an alcohol and the carboxylic acid !!Aa gai aqal?

alrught alright! ChillI have the concepts of organic well!! U mentioned esters hydrolysis in naoh presence just which means dat the reaction will produce an alcohol and the carboxylic acid !!
Isn't voltage directly proportional to the currentIt's confusing
Current decreases when Resistance increase.
And yes, voltage increase then current decreases.
Well I used the theory that why is power transmitted over high voltage? That's cuz high voltage means less current, isn't that right?Isn't voltage directly proportional to the current
people one point... in the series combination of resistors greater the resistance greater the voltage across it so voltage divides proportionallyits there in the Xtreme Revision section...
Mods please look to it...
dude total voltage doesnt change... it divides proportionally across each resistor so if one resistor is 20 and the other 30 ohm voltage divides in the ratio 2:3... same is the case with a potential dividerin mentioned case ... when resistance is increased,voltage should be increased if it would not be constant!! In this case just current would decrease, keeping the equation valid!! i.e v=ir , r increased therfore i decrease so v = same(6 volts)!!!!!
grams.... duh.. done this question a million timeswhats the unit for the sample..
so the mole ratio will be 1:1 so 60/24 whatever that gives is the number of moles of the sample as well as one double bond means all of h2 reacted so then divide 0.5 by the number of moles. (in easy words one double bode consumes one h2 molecule so mole ratio is one ratio one) Not at all rocket sinceA 0.50 sample of vegetable oil reacted with 60cm^3 of hydrogen,measured at r.t.p
Assuming tht one molecule of the oil contains only one double bond calculate the relative molecular mass of the oil !

Yes sure... whatever keeps you happy... you don't have to get all madI have the concepts of organic well!! U mentioned esters hydrolysis in naoh presence just which means dat the reaction will produce an alcohol and the carboxylic acid !!

Method is right but the 60 cm^3 won't be changed to dm^3 by the examinerso the mole ratio will be 1:1 so 60/24 whatever that gives is the number of moles of the sample as well as one double bond means all of h2 reacted so then divide 0.5 by the number of moles. (in easy words one double bode consumes one h2 molecule so mole ratio is one ratio one) Not at all rocket since
thats what i m saying !!!!

The answer is D ..i wanna know y isnt i

The answer is D ..i wanna know y isnt it C :/
This is because as P=F/A thus Pressure is inversely proportional to area. In C the graph is not that of inverse proportionality and in D it is........ So D is the answer..
Haha wasnt mad at all. I had sme misunderstandings tht got cleared last night : D thnx anyway !Yes sure... whatever keeps you happy... you don't have to get all mad
We use the POWER equation when speaking if transmission cables. I.E. I = P/V
Notice that, in this equation, Current is INVERSELY proportional to voltage.
In simple circuits, we use I = V/R where I is directly proportional to the voltage.
Method is right but the 60 cm^3 won't be changed to dm^3 by the examiner
Got cleared? So, what was your answer?Haha wasnt mad at all. I had sme misunderstandings tht got cleared last night : D thnx anyway !
Actually i didnt read tht u asked hydrolisis by naoh .i jst wrote the answer ,hydrolisis of ester by h2oGot cleared? So, what was your answer?
AlhamdulillahActually i didnt read tht u asked hydrolisis by naoh .i jst wrote the answer ,hydrolisis of ester by h2o
Ester + naoh = alcohol + ester salt
Ester + h20 = alcohol + carboxylic acid
wat else was i trying 2 tell u last night miss?Actually i didnt read tht u asked hydrolisis by naoh .i jst wrote the answer ,hydrolisis of ester by h2o
Ester + naoh = alcohol + ester salt
Ester + h20 = alcohol + carboxylic acid
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.
