1. CH4 + 2O2 = CO2 + 2H20 B.
2. 2CH2H6 + 7O2 = 4CO2 + 6H20 A
3. C3H8 + 502 = 3CO2 + 4H20 C
<h3>
How to determine the appropriate products of reaction</h3>
To find the appropriate end products, use the following rules
- The hydrogen ratio should be the same on both the product and reactant sides
- The oxygen ratio should be the same on both the product and reactant sides
- The carbon ratio should be the same on both sides.
Thus for equation;
1. CH4 + 2O2 = CO2 + 2H20 B.
2. 2CH2H6 + 2O2 = 4CO2 + 6H20 A
3. C2H8 + 502 = 2CO2 + 4H20 C

Answer : The 
for this reaction is, -88780 J/mole.
Solution :
The balanced cell reaction will be,
Here, magnesium (Cu) undergoes oxidation by loss of electrons, thus act as anode. silver (Ag) undergoes reduction by gain of electrons and thus act as cathode.
The half oxidation-reduction reaction will be :
Oxidation : 
Reduction : 
Now we have to calculate the Gibbs free energy.
Formula used :
where,
= Gibbs free energy = ?
n = number of electrons to balance the reaction = 2
F = Faraday constant = 96500 C/mole
= standard e.m.f of cell = 0.46 V
Now put all the given values in this formula, we get the Gibbs free energy.
Therefore, the for this reaction is, -88780 J/mole.
A. 4 mm.......0.5 mm
B. 1.5 mm......same size
