a. HCl + NaOH - → NaCl + H,O + heat
b. 2KCIO,(s) A 2KCI(s) + 30,
c. CaO+H2O + Ca(OH), #heat
d. CaCO3(s) + CaO(s) + CO,
A​

Answer 1

Answer:

Sorry, I know only a.) part .

Here is the answer:

Hydrochloride acid + Sodium hydroxide = Sodium chloride + Water + Heat

That's the answer.

That's the answer.if yes then give me thanks.

Answer 2

Explanation:

(a)HCl+NaOH⟶NaCl+H 2O+heat

it is neutrilisation reaction and neutrilisation reactions are exothermic,

(b)2KClO3 (s)+heat⟶2KCl+3O 2 (g)

Energy is require to break the bonds of KKClO, it is endothermic reaction.
