usually referring to chemical elements that are solid
Answer:
Option D. T
Explanation:
Enthalpy change (ΔH) is simply the difference between the heat content of the product (Hp) and the heat content of the reactant (Hr). Mathematically, it is expressed as:
Enthalpy change (ΔH) = Heat of product (Hp) – heat of reactant (Hr)
ΔH = Hp – Hr
From the diagram given above, the difference between the heat content of product and the heat content of reactant is T.
Therefore, the enthalpy change of the reaction is T.

Let us study about this reaction </h2>
Explanation:
This given reaction is a chemical reaction that is : Double decomposition reaction .
In this reaction , there is a reaction between two compounds in which they mutually interchange their ions .
That is :
AB +CD ---> AC +BD
Similarly in this we have :
Na3PO4+KOH—->NaOH + K3PO4
The double decomposition reaction is either :
Precipitation reaction : resulst in the formation of ppt .
Neutralization reaction : results in the formation of neutral substance
