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

In the reaction , calcium (Ca) is oxidized.Oxidation refers to the process in which an atom, ion, or molecule loses electrons. In this reaction, calcium (Ca) loses electrons and forms calcium oxide (CaO). The oxygen in gains electrons and is reduced to form calcium oxide (CaO). Therefore, calcium (Ca) is oxidized in this reaction.
