Substances are given: sodium hydroxide solution, silicon oxide (IV), diluted sulfuric acid, aluminum chloride solution, calcium carbonate, zinc, sodium sulfide solution, carbonic acid gas. Write down the equations of all possible reactions between them.

CaCO3 + H2SO4 = CaSO4 + CO2 + H2O
CaCO3 + SiO2 = CaSiO3 + CO2
2AlCl3 + 3Na2S + 6H2O = 2Al(OH)3 + 3H2S + 6NaCl
Zn + H2SO4 = ZnSO4 + H2
Na2S + H2SO4 = Na2SO4 + H2S
