C) a voltaic cell consists of zn/zn2+ half-cell and a ni2+/ni half-cell at 25°c.
i. what is the initial concentration if the initial concentration of ni2+ and zn2+ are
1.75 m and 0.15 m, respectively?
ii. what is the cell potential when the concentration of ni2+ has fallen to 0.45 m?
ii.
what is the number mole of zn2+ in 500 ml solution if ecell is 0.6 v and [ni2+]
is 2.8 m

To prevent the presence of air, noble gases are placed over highly reactive chemicals to act as inert "blanketing" gases. a chemical engineer places a mixture of noble gases consisting of 4.37 g of he, 13.36 g of ne, and 36.65 g of kr in a piston-cylinder assembly at stp. calculate the partial pressure in torr of kr.

In a chemical reaction, the final amount of the products is determined by the a. universal gas law b. law of definite proportions c. air pressure d. temperature e. none of the above me
