2 Identify the oxidizing and reducing agents in these reactions, by looking at the gain and loss of oxygen: a 2Mg (s) 1 O2 (g) 2MgO (s)

Answerδh > 0explanationc₆h₆  (s)  → c₆h₆ (l)if you are changing it from a solid to a liquid, you are pretty much melting the solid. this requires heat energy. therefore, the reaction is endothermic (takes in energy); the system enthalpy increases as the reaction proceeds: δh > 0.

Hi + naoh -> h2o + nal
