Nickel can be planted from aqueous solution according to the following half reaction. how long would it take (in min) to plate 29.6 g of nickel at 4.7 a?

Time=345.7 min

Explanation:

It is an example for Faraday's first law of Electrolysis

It states that the amount of substance deposited is directly proportional to the amount of electricity passed.

W=Zit

Z=E/96500

W= E it/96500

And E=58.7(molar mass of Ni)/2(charge on Ni)=29.3

t=W96500/E i

= 29.6x96500/29.3x4.7

= 20742.1 sec

=345.7 min

smooth muscle is composed of involuntary muscles found within the walls of organs and structures such as the esophagus, stomach, intestines, and blood vessels. those muscles push materials like food or blood through organs. unlike skeletal muscle, smooth muscle can never be under your control.
