Calcium is obtained industrially by electrolysis of molten cacl2 and is used in aluminum alloys. how many coulombs are needed to produce 19.2 g of ca metal? if a cell runs at 15 a, how many minutes will it take to produce 19.2 g of ca(s)?

Explanation:

The given data is as follows.

           m = 19.2 g,             I = 15 A

The given reaction equation will be as follows.

As, 1 mole will give of charge. So, calculate the amount of charge deposited by 19.2 g as follows.

                = 94404.791 C

Hence, 94404.791 C are needed to produce 19.2 g of Ca metal.

Therefore for 15 A, minutes required to produce 94404.791 C and 19.2 g of Ca(s) will be calculated as follows.

                =

                = 104.9 mins

Thus, we can conclude that 104.9 minutes are required if a cell runs at 15 A, how many minutes will it take to produce 19.2 g of Ca(s).
