Calculate the thickness on electroplating a plate of copper by gold (Au= 196) using gold solution if the density of gold = 13 g/cm3 and the

surface area of the plate is = 100 cm2

the electroplating for one side

if the amount of electricity passed = 0.2 mole electron the answer is​

100 points answer quick the table compares the number of electrons in two unknown neutral atoms. comparison of electrons atom number of electrons a 10 d 11 use this information to determine the number of valence electrons in the atoms. which of the following correctly compares the stability of the two atoms? both are unreactive. both are highly reactive. a is unreactive and d is reactive. a is reactive and d is unreactive.
