Answer: It takes 193000 seconds to plate out exactly 1.00 mol of nickel metal, assuming 100 percent current efficiency.
Explanation:
1 electron carry charge=
1 mole of electrons contain= electrons
Thus 1 mole of electrons carry charge=
of electricity deposits 1.00 mole of nickel
where Q= quantity of electricity in coloumbs = 193000 C
I = current in amperes = 1.00 A
t= time in seconds = ?
Thus it takes 193000 seconds to plate out exactly 1.00 mol of nickel metal, assuming 100 percent current efficiency.
Answer: Formation of precipitate indicates that there has been a chemical reaction.
Explanation:
Chemical reaction: It is defined as change in arrangement of the atoms so as to form a new substance.
Mixing of two clear solutions that is lead nitrate and potassium iodide gives out yellow solid precipitate of lead iodide with aqueous solution of potassium nitrate.
The physical evidence which indicates that chemical reaction has been taken place is formation of yellow solid precipitate of lead iodide ,().
