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.

No Barrel of Slime Isn't toxic ( Smiles )
Answer:
No, just because carbon did not react with water, does not mean it wouldn't react with a different compound.
Explanation:
It is common knowledge that carbon is not in group 18, because it is found in all living compounds, and this means it must be reactive with many compounds. We know that water is not very reactive, but it is a good solvent. Meaning that many compounds can dissolve in water, but not chemically react with it. Carbon however is not very soluble because it does not create dipoles or hydrogen bonds. This means it will not show any change when in the presence of water, but if combined with oxygen, can form carbon dioxide.
