Consider the reaction corresponding to a voltaic cell and its standard cell potential. z n ( s ) + c u 2 + ( a q ) ⟶ c u ( s ) + z n 2 + ( a q ) zn(s)+cux2+(aq)⟶cu(s)+znx2+(aq) e o cell = 1.1032 v ecello=1.1032 v what is the cell potential for a cell with a 2.700 m solution of z n 2 + ( a q ) znx2+(aq) and 0.1448 m solution of c u 2 + ( a q ) cux2+(aq) at 436.2 k? c

When the earth was formed and cooled, why did nickel and iron end up in the center of the earth while basalt and granite ended up in the outer layers

At a temperature of 393 k, the temperature of a sample of nitrogen is 1.07 atm what will the pressure be at a temperature of 478 k

Salicylic acid is a very important acid. it is used to synthesize the aspirin by treating with acetic anhydride. a 0.2015-g sample of salicylic acid was dissolved in a 100.00-ml volumetric flask, and the solution was diluted to the mark. a 10-ml aliquot of this solution was titrated with standard naoh (0.01130 + 0.2% n) to a phenolphthalein faint pink color end point at 19.81 ml. (a) (calculate the normality of the salicylic acid solution used in the titration. (b) assuming the salicylic acid is pure, what is the equivalent weight of the salicylic acid? practice problems for the final exam (continued) (c) (calculate the inherent error in the determination of the equivalent weight you calculated in part (b). use the following absolute errors in the equipment /glassware when calculating the inherent error. 5.00-ml pipet: + 0.02 ml 100-ml volumetric flask: + 0.08 ml analytical balance: + 0.2 mg 25-ml buret: + 0.03 ml
