Answer:

Explanation:

After the glorious appearance of Full Moon, the lunar shape starts to wane, meaning it gets smaller. It's visible later at night and into the early morning, and we see a steadily shrinking shape of the lunar surface that's being lit up.

What current (in a) is required to plate out 2. 96 g of nickel from a solution of ni2 in 27. 12 minutes?
amid [387]

The current required to plate out 2.96 g of nickel from the solution of Ni²⁺ in 27.12 minutes is 5.95 A

<h3>Balanced equation </h3>

We'll begin by writing the balanced equation showing the number of faraday required to plate nickel. This is given below

Ni²⁺ + 2e —> Ni

Molar mass of Ni = 59 g/mol

Mass of Ni from the balanced equation = 1 × 59 = 59 g

Number of faraday = 2 F

1 faraday = 96500 C

2 faraday = 2 × 96500 = 193000 C

SUMMARY

From the balanced equation above,

59 g of Nickel was deposited by 193000 C of electricity

<h3>How to determine the quantity of electricity </h3>

From the balanced equation above,

59 g of Nickel was deposited by 193000 C of electricity

Therefore,

2.96 g of Nickel will be deposited by = (2.96 × 193000) / 59 = 9682.71 C of electricity

<h3>How to determine the current </h3>
  • Quantity of electricity (Q) = 9682.71 C
  • Time (t) = 27.12 mins = 27.12 × 60 = 1627.2 s
  • Current (I) =?

I = Q / t

I = 9682.71 / 1627.2

I = 5.95 A
