Write the equation of possible reactions between sulfuric acid with the following substances: Li2CO3; Pt; Fe2O3; SiO2; NaOH; SrCl2; Zn; Al (OH) 3; give the equation of reactions in molecular and ionic form.

1) Li2CO3 + H2SO4 = Li2SO4 + H20 + CO2 (gas)
2Li (1 +) + CO3 (2 -) + 2H (+1) + SO4 (2 -) = 2Li (1 +) + SO4 (2 -) + H2O + CO2
CO3 (2 -) + 2H (+1) = H2O + CO2
2) Pt + H2SO4 the reaction will not work
3) Fe2O3 + 3H2SO4 = Fe2 (SO4) 3 + 3H20
Fe2O3 + 6H (+1) + 3SO4 (2 -) = 2Fe (2 +) + 3SO4 (2 -) + 3H20
Fe2O3 + 6H (+1) = 2Fe (2 +) + 3H20
4) SiO2 + H2SO4 the reaction will not work
5) 2NaOH + H2SO4 = Na2SO4 + 2H2O
2Na (1 +) + 2OH (1 +) + 2H (+1) + SO4 (2 -) = 2Na (1 +) + SO4 (2 -) + 2H2O
2OH (1 +) + 2H (+1) = 2H2O
6) SrCl2 + H2SO4 = SrSO4 (precipitate) + 2HCl
Sr (2 +) + 2Cl (1 -) + 2H (1 +) + SO4 (2 -) = SrSO4 + 2H (1 +) + 2Cl (1-)
Sr (2 +) + SO4 (2 -) = SrSO4
7) Zn + H2SO4 = ZnSO4 + H2 (gas)
Zn + 2H (1 +) + SO4 (2 -) = Zn (2 +) + SO4 (2 -) + H2
Zn + 2H (1 +) = Zn (2 +) + H2
8) 2Al (OH) 3 + 3H2SO4 = Al2 (SO4) 3 + 6H2O
2Al (OH) 3 + 6H (1 +) + 3SO4 (2 -) = 2Al (3 +) + 3SO4 (2 -) + 6H2O
2Al (OH) 3 + 6H (1 +) = 2Al (3 +) + 6H2O
