Question

odd one out 2KCIO3 -- 2KCI + 3021, HCI + NaOH - NaCl + H2O + Heat, CaCO3 -- CaO + CO2​

Answer 1

Answer:

HCl + NaOH ---> NaCl + H2O + heat

Explanation:

HCl + NaOH ---> NaCl + H2O + heat is the odd one, because in this equation the particles are combining to form a reactant.

Whereas, in other 2 equation, particle is reducing to its simpler parts/elements/molecules/compound.

therefore, 2nd equation is odd.
