Write the balanced chemical equation for the standard enthalpy of formation of P4O10(s). Be sure to include the phases

4 P(s, white) + 5 O₂(g) ⇒ P₄O₁₀(s)

Explanation:

The standard enthalpy of formation of P₄O₁₀(s) is the energy required to synthesize 1 mol of P₄O₁₀(s) from the simple substances in their most stable form. The corresponding balanced chemical equation is:

4 P(s, white) + 5 O₂(g) ⇒ P₄O₁₀(s)

P(s, white) is the most stable allotropic form of phosphorus. The standard enthalpy of formation of P₄O₁₀(s) is -2984 kJ/mol.
