In the reaction 2Ca(s)+O_(2)(g)arrow 2CaO(s) -> 2 CaO(s),calcium is __ Oxidized Reduced Synthesized None of the above

In the reaction $2Ca(s)+O_{2}(g)\rightarrow 2CaO(s)$, calcium is oxidized.<br /><br />Oxidation is the process of losing electrons or gaining oxygen. In this reaction, calcium (Ca) is losing electrons and gaining oxygen to form calcium oxide (CaO). Therefore, calcium is being oxidized.
