At a particular temperature, for the following balanced reaction: 2N2(g) O2(g) -> 2N2O (g) In an experiment in which 1.0 mol of and 1.5 mol of are mixed in a 2.0-L vessel, what are the equilibrium concentrations of all gases

Where are the following questions

The formula is (nh4)2co3

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.
