im guessing a natural resource? sorry thats the only answeri can think of
When one or more reactants change into one or more new substances
Answer: 8.95 hours
Explanation:
Coloumb of electricity deposits 1 mole of Nickel
1 mole of Nickel weighs = 58.7 g
Given quantity = 1.0 kg = 1000 g (1kg=1000g)
58.7 g of Nickel is deposited by 193000 C of electricity
1000 g of Nickel is deposited by = of electricity
where Q= quantity of electricity in coloumbs = 3287904.6C
I = current in amperes = 102 A
t= time in seconds = ?
(1h=3600 sec)
Thus 8.95 hours it takes to plate out 1.0 kg Ni from aqueous solution, if the electrical current is 102 A.
