Hi all(adsbygoogle = window.adsbygoogle || []).push({});

Q1 : when a run down battery is recharged 22600C of charge is required comput the time in hour needed to recharge the battery to 8A current ?

my answer is : t = Q / I = 22600 / 8 = 2825

Q2 : calculate the number of Faraday required depositing 1 X 10^-5moles of cu from cu^2 ?

my answer is

Cu ----- > cu^2+

the charge of cu = 3

the number of Faraday needed to deposit 1 mole will be = 3F

the number of Faraday needed to deposit 1 X 10^-5 mole will be = 3F X 1 X 10^-5

= 3 X 10^-5 F

I want check my solving

thanks
