Question

The reaction Zr (s) + O2(g) = ZrO2 (s) is an example of oxidation reduction, acid-base, or precipitation

Answer 1

Answer: precipitation reaction

Explanation: This reaction does not involve any transfer of electrons, so it is not an example of an oxidation-reduction reaction. It also does not involve the transfer of a proton (H+), so it is not an example of an acidbase reaction. Finally, it does not involve the formation of a solid from a solution, so it is not an example of a precipitation reaction
