TSEET STRUCTURE
States that the amount of substance produced during electrolysis is directly proportional to the amount of electric charge that flow through the electrolyte
states that the amount of different substances produced by the same amount of electric charge is inversely proportional to the charge of the ions
Q=It t = 96500 2.00 = 18250s =13.4h
F=Nae = 96500 6.02x 1023
= 1.60x10-19 C
Cu2+ +2e Cu 2Cl- Cl2 + 2e
2 moles of electronic charge = 2F needed to electrolyse 1 mol of CuCl2
Ecell = Ecathode - E anode
= +1.16v
Spontaneous reaction
Orange turns green

2- + H2O
Cd2+ / Ni2+/ Cr3+

ANSWER
18a) Enthalpy of formation of carbon dioxide is heat released when 1 mol mole of carbon dioxide formed from its elements under standard condition
C(s) + ½ O2 (g) CO (g)
CO2 (g)
½ O2 O2
b)
-110.5
-393.5ΔH = (-393.5) – (-110.5) = -283.0 kJmol-1
CO + ½ O2 CO2
ΔH
AgCl is less soluble than NaClAg less electropositive tha NaDifference in electronegativity between Ag and Cl is less than Na and ClNaCl is ionic compound meanwhile AgCl is ionic compound that show covalent charateristics.
