The price of an article is increased by 40% as a result its sale is decreased by 20%. Find the % of effect on revenue collection.

Total increase/decrease = (x + y + xy/100)

Can i use this formula here????

Here x = + 40 and y = - 20

so increase/decrease = + 40 - 20 - 40*20/100 = + 12 % <---------

+ sign means increase.

The dissociation constant of water at 323K is 2.84 x 10^- 14. Find the Ph of the water at 323 K. And explain a solution of Ph = 6.94 at 323 K is acidic or basic ??

Cryoscopic Constant :

How we can calculate Cryoscopic Constant of Water ??

Fe3+ + e -------> Fe2+ , E0(298) =0.77 V

Fe2+ +2e --------> Fe , E0(298) = 0.44 V

then find E0 for the reaction Fe3+ + 3e -------> Fe and also find delta G0
