What mass of Cu(s) is electroplated by running 30.0 A of current through a Cu2 (aq) solution for 4.00 h

The correct answer is "142 g".

Explanation:

According to the question,

⇒

where,

Z = 2

F = 96500c

C = 30 A

t = 4h

 =

 =

We know that,

Atomic mass of Cu(M) = 63.5 g/mole

Now,

⇒

On putting the values, we get

warm front forms when a moist, warm air mass slides up and over a cold air mass. as the warm air mass rises, it condenses into a broad area of clouds. a warm front brings gentle rain or light snow, followed by warmer, milder weather.
