The mass of Copper deposited at the cathode : 0.296 g
<h3>Further explanation</h3>Given
time = t = 10 min=600 s
current = i = 1.5 A
F = 96500 C
charge Cu=+2
Required
The mass of Copper
Solution
Faraday's Law
e = Ar/valence(valence Cu=2, Ar=63.5 g/mol)
Input the value :
The final temperature : T₂ = 680.625 K
<h3>Further explanation</h3>Given
V₁=240 ml
T₁ = 90 + 273 = 363 K
V₂ = 450 ml
Required
The final temperature
Solution
Charles's Law
When the gas pressure is kept constant, the gas volume is proportional to the temperature
Input the value :
T₂ = V₂T₁/V₁
T₂ = 450 x 363 / 240
T₂ = 680.625 K
