Answer:
Redox reactions
Explanation:
Redox reactions consists of both oxidation and reduction
one species gets oxidised and other species become reduced, both oxidation and reduction happen simultaneously
reduction is either gain of electrons or gain of hydrogen. in reduction the oxidation number of species reduces
in this reaction the reduction half equation is
O₂ + 4e --> 2O²⁻
oxidation is either loss of electrons or gain of oxygen. in oxidation the oxidation number of species increases.
Fe --> Fe²⁺ + 2e
since both these half reactions happen overall its a redox reaction

Answer : The correct option is, The concentration of the acid.
Explanation :
Molarity : Molarity is defined as the moles of solute present in one liter of the solution. Or it is defined as the concentration of solute present in one liter of solution.
The unit of molarity is, (M) i.e, mole/liter. It is also known as molar concentration.
Molarity of 0.01 M means, 0.01 concentration of the acid present in the solution.
Therefore, the 0.01 M refer to the concentration of the acid.
I think the correct answer from the choices listed above is option B. The formation of frost on a cold windowpane is an example of condensation. This process involves the phase change from the vapor phase to the liquid phase.
