In which of the following reaction- dihydrogen acts as an oxidising agent-Ca-H-2-rightarrow H-2-O-2-rightarrow H-2-F-2-rightarrow CuO-H-2-rightarrow

As the calcium is having 2 electrons more -1s2-2s2-2p6-3s2-3p6-4s2- than the inert gas configuration- so it can give its two electrons to two hydrogens leading to the formation of CaH2 and cause oxidation in Ca-Ca-H2-x2192-CaH2Here- hydrogen is acting as the oxidising agent-

In which of the following reaction, dihydrogen acts as an oxidising agent?Ca+H2→H2+O2→H2+F2→CuO+H2→

As the calcium is having 2 electrons more (1s2,2s2,2p6,3s2,3p6,4s2) than the inert gas configuration, so it can give its two electrons to two hydrogens leading to the formation of CaH2 and cause oxidation in Ca.Ca+H2→CaH2Here, hydrogen is acting as the oxidising agent.
