Rules:
1) The oxidation number of a monatomic ion equals the charge of the ion.
2)The oxidation number of a Group 1 element in a compound is +1.
3) The oxidation number of a Group 17 element in a binary compound is -1.
4) The sum of the oxidation numbers of all the atoms in a neutral compound is 0.
KCl is an ionic compound. Consists of K+ ions and Cl- ions.
Oxidation of K= +1 (rules 1 and 2)
Oxidation of Cl= -1 (rules 1 and 3)
Rule 4 also applies- +1 + (-1)= 0- a neutral compound
Hope this helps :)

I can't answer the question without the statements but I can tell you Calorimetry means measuring amounts of heat released or received during a chemical reaction.
