Answers & Comments
Li₂O + H₂O = 2LiOH;
2LiOH + 3S = Li₂S + H₂S + SO₂;
Li₂S + 2HCl = LiCl + H₂S;
H₂S + O₂ = SO₂ + H₂O.
2). 2Li + 2H₂O = 2LiOH + H₂.
3). 6LiOH + Fe₂(SO₄)₃ = 3Li₂SO₄ + 2Fe(OH)₃;
2Fe(OH)₃ = Fe₂O₃ + 3H₂O;
Fe₂O₃ + 6HCl = 2FeCl₃ + 3H₂O.
4). 2Fe(OH)₃ + 3H₂SO₄ = Fe₂(SO₄)₃ + 6H₂O.

5 2H2S+3O2=2SO2+2H2O
2)
Li+O2=2LiO
Li2O+H2O=2LiOH
3)
6LiOH+Fe(SO4)3=2Fe(OH)3+3Li2SO4
2Fe(OH)3=Fe2O3+3H2O
Fe2O3+6HCl=2FeCl3+3H2O
4)
2Fe(OH)3+3H2SO4=Fe2(SO4)3+6H2O
