Choose the thermochemical equation that illustrates ΔH°_f for Li₂SO₄. A) 2 Li⁺(aq) + SO₄^2-(aq) → Li₂SO₄(aq) B) 2 Li(s) + 1/8 S₈(s, rhombic) + 2 O₂(g) → Li₂SO₄(s) C) Li₂SO₄(aq) → 2 Li⁺(aq) + SO₄^2-(aq) D) 8 Li₂SO₄(s) → 16 Li(s) + S₈(s, rhombic) + 16 O₂(g) E) 16 Li(s) + S₈(s, rhombic) + 16 O₂(g) → 8 Li₂SO₄(s)
