Final answer:

The exact amount of kilojoules of heat released when 1 mole of manganese is burned to form Mn3O4 at standard state conditions is not provided in the reference information, and therefore cannot be determined from the data given.

Step-by-step explanation:

The amount of heat released when 1 mole of manganese (Mn) is burned to form Mn3O4 (manganese(II,III) oxide) can be determined using enthalpy change concepts similar to stoichiometry problems.

However, based on the reference information provided, a precise figure for this reaction is not given, hence we cannot accurately answer the original question.

Typically, this would involve looking up the standard enthalpy of formation for Mn3O4 and using stoichiometry to calculate the heat released.

The reaction is exothermic, which means that the sign of ΔH is negative, indicating that heat is released. Without the specific enthalpy change values, an exact numerical answer cannot be provided.
