Sr (s) + C (s) + 3/2 O₂ (g) → SrCO₃ (s)

Explanation:

The standard enthalpy of formation (ΔH°f) is the energy involved in the formation of 1 mole of a substance from its elements in their most stable states. The chemical equation for the formation of SrCO₃ (s) is the following.

Sr (s) + C (s) + 3/2 O₂ (g) → SrCO₃ (s)
