Answer: Option (C) is the correct answer.
Explanation:
In a chemical reaction equation, the number of species or molecules written on the left hand side denote reactants whereas the species or molecules written on the right hand side denote products.
For example, in the given equation, . Left hand side molecule is
and it is the reactant. Whereas the molecules or species on right hand side are S and
and these are the products.
Thus, we can conclude that the product(s) in this equation would be S + O2.

Answer:
1.346 v
Explanation:
1) Fist of all we need to calculate the standard cell potential, one should look up the reduction potentials for the species envolved:
(oxidation) →
E°=0.337 v
(reduction) →
E°=1.679 v
(overall) +8H^{+}_{(aq)}→
E°=1.342 v
2) Nernst Equation
Knowing the standard potential, one calculates the nonstandard potential using the Nernst Equation:
Where 'R' is the molar gas constant, 'T' is the kelvin temperature, 'n' is the number of electrons involved in the reaction and 'F' is the faraday constant.
The problem gives the [red]=0.66M and [ox]=1.69M, just apply to the Nernst Equation to give
E=1.346
