During the electrolysis of cooper (11) sulphate soIution , if 0.5 faraday (48250 c) is used what mass of copper will be deposited
at the cathode.

imma come back to you hold on

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z

answer

the answer is c.the valence of the atoms combine .
