<span>d)Electrons need specific amounts of energy to "jump" off an atom and be emitted.</span>
Answer&Explanation:
The unit used to measure Heat is joule equal to that of Energy and is abbreviated as (J)
Data Given:
Time = t = 30.6 s
Current = I = 10 A
Faradays Constant = F = 96500
Chemical equivalent = e = 63.54/2 = 31.77 g
Amount Deposited = W = ?
Solution:
According to Faraday's Law,
W = I t e / F
Putting Values,
W = (10 A × 30.6 s × 31.77 g) ÷ 96500
W = 0.100 g
Result:
0.100 g of Cu²⁺ is deposited.
