Which of the following chemical equations corresponds to the standard molar enthalpy of formation of Na2CO3(s)? 2Na(s) + C(s) + 3/2O2(g) → Na2CO3(s)
2Na(s) + C(s) + 3O(g) → Na2CO3(s)
Na2O(s) + CO2(g) → Na2CO3(s)
Na2O2(s) + CO(g) → Na2CO3(s)
Na2(s) + C(s) + 3O(g) → Na2CO3(s)

coral.

explanation:

coral. many marine organisms that produce calcium carbonate shells or skeletons are negatively impacted by increasing co2 levels and decreasing ph in seawater.
