WebMar 30, 2024 · Answer: +2. explanation : An example of a +2 oxidation state is CuO, where oxygen has an oxidation number of -2 and therefore copper has the oxidation number of +2 to balance out the molecule. An example of a +1 oxidation state is Cu2O, where, once again, oxygen's oxidation state is -2 and so to balance out the molecule, each copper atom is +1. WebSummary. Oxidation is the gain of oxygen (O) while reduction is the loss of oxygen (O). Oxidation is the loss of hydrogen (H) while reduction is the gain of hydrogen (H). Oxidation and reduction reactions must occur together. The reactant oxidized is the reducing agent. The reactant reduced is the oxidizing agent. build your acura tlxWebFeb 1, 2024 · In the case of 1 wt% NH 4 Cl−Cu 2 O−NCs, the selectivity towards acetone and propanal sharply increases in the temperature range of 150–225 °C, while the CO 2 selectivity does not change very much (13.0–25.6%).
