Answer: 2KClO3 → 2KCl + 3O2
Explanation: Quite simple, it's the only one that was broken down into more parts than the start, the rest were simply reseperated
lets start with the other options
(B. 4Na + O2 → 2Na2O)
well that is 2 → 1, it's synthesis
(C. ZnS + 3O2 → 2ZnO + 2SO2)
this is a single replacement reaction because oxygen is replacing Zn and S in ZnS to form ZnO and plus SO₂.
(2NaBr + CaF₂ → 2NaF + CaBr₂) is a double replacement reaction because two ions (Br⁻ from NaBr and F⁻ from CaF₂) are exchanging places with other two ions (Na⁺ from NaBr and Ca²⁺ from CaF₂) two form two new ionic compounds (NaF and CaBr₂).
