Answer

Choose the thermochemical equation that illustrates ΔH°f for Li2SO4.

A) 2 Li+(aq) + SO42-(aq) → Li2SO4(aq)
B) 2 Li(s) + 1/8 S8(s, rhombic) + 2 O2(g) → Li2SO4(s)
C) Li2SO4(aq) → 2 Li+(aq) + SO42-(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)
