(5)
(b) Second law of thermodynamics states that total entropy of system and surroundings always increases in spontaneous process.
(6)
a redox reaction is a reaction in which both reduction and oxidation occurs.
(b) in this part Al gets oxidized from state 0 to +3 and H gets reduced from +1 to 0
(7)
Oxidation occurs at anode.
(c) in this part Zn gets oxidized from state 0 to +2
in all other cases it gets reduced.
(8)
(e) oxidation occurs at anode and reduction at cathode, without salt bridge cell reaction will stop after sometime.

16. The total entropy of a system and its surroundings always increases for a spontan process. This is a statement of A) the law of constant composition. B) the first law of thermodynamics. C) the second law of thermodynamics. D) the third law of thermodynamics. the law of conservation of matter. 17. The standard enthalpy of vaporization of chloroform is 29.2 kJ/mol at its normal point, 61.2°C. What is the standard change in entropy for the vaporization of chloroform at...
Is #3 correct? "Sn(s)/Sn+2(aq) // Cu+2(aq)/Cu(s)"
Also, I need help with #4 and #5.
Thanks! (will rate!)
Section A. Constructing a Small-Scale Electrochemical Cell Objective To construct a small-scale electrochemical cell using a redox system, to measure the cell potential and derive thermodynamic quantities. Procedures 1. Connect the red and black alligator clips to the multimeter to read voltage. Set up the multimeter to read DC (direct current) voltage using the tab at the top. 2. Cut the filter paper...
