The oxidation number of Mn is 0. Details about oxidation number can be found below.
<h3>What is oxidation number?</h3>
Oxidation number is the hypothetical charge of an atom within a molecule.
However, when an atom exists independently as an element, the oxidation number of such element is 0.
The oxidation number is assigned to an atom in a element/compound. It can either be +, -, or 0 and it tells us if electrons are lost or gained.
Therefore, according to this question, the oxidation number of Mn is 0.

21 Anabolic steroid abuse can lead to kidney and liver failure, enlarged heart or high blood pressure and changes in blood cholesterol.
The standard temperature and pressure conditions enthalpy is usually measured under are 1kPa and 273K (option A).
<h3>What is enthalpy?</h3>
Enthalpy in thermodynamics is a measure of the heat content of a chemical or physical system.
Enthalpy is the sum of the internal energy and pressure times volume It can be calculated using the following formula:
H = E + P V
Where;
H = Enthalpy
E = internal energy
P = pressure
V = volume
However, the enthalpy of a substance is usually measured under standard temperature and pressure.
- The standard temperature is 273 Kelvin or K
- The standard pressure is 1kPa
