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

conduction is the transfer of thermal energy (heat in transfer) due to collisions between the molecules in the object. collisions between adjacent atoms and molecules transfer kinetic energy from the warmer to the cooler object. the objects must be in physical contact.

a gas, having a molecular weight of 13 kg/kmol and a kinematic viscosity of 0.25 cm2/s, flows through a pipe 0.25 m internal diameter and 5 km long at the rate of 0.4 m3/s and is delivered at atmospheric pressure.
