Question
Choose the thermochemical equation that illustrates ?H0f for Li2SO4.
H2S (g) + 3O2 (g) <=> 3H2O (g) + SO2 (g)
8 Li2SO4 (s) ----- > 16 Li (s) + S8 (s, rhombic) + 16 O2
Li2SO4 (aq) ----- > 2 Li+ (aq) + SO42- (aq)
2Li (s) + 1/8 S8 (s, rhombic + 2 O2 ------ > Li2SO4 (s)
2 Li+ (aq) + SO42- (aq) -----> Li2SO4 (aq)
16 Li (s) + S8 (s, rhombic + 16 O2 ----- > 8 Li2SO4 (s)
8 Li2SO4 (s) ----- > 16 Li (s) + S8 (s, rhombic) + 16 O2
Explanation / Answer
2 Li(s) + 1/8 S8(s, rhombic) + 2 O2(g) ? Li2SO4(s)
