# Which of the substances: O2, Na, AI2O3, CO2, H2SiO3, K3PO4, SiO2, Au, Fe (OH) 3 does dilute sulfuric acid interact with?

Which of the substances: O2, Na, AI2O3, CO2, H2SiO3, K3PO4, SiO2, Au, Fe (OH) 3 does dilute sulfuric acid interact with? Make the equations of reactions in molecular and ionic form, name all substances

1) 2Na + H2SO4 = Na2SO4 + H2
sodium, sulfuric acid, sodium sulfate, hydrogen
2Na + 2H (+) + SO4 (2 -) = 2Na (+) + SO4 (2 -) + H2

2) Al2O3 + 3H2SO4 = Al2 (SO4) 3 + 3H2O
aluminum oxide, sulfuric acid, aluminum sulfate, water
Al2O3 + 6H (+) + 3SO4 (2 -) = 2Al (3 +) + 3SO4 (2 -) + 3H2O

3) 2Fe (OH) 3 + 3H2SO4 = Fe2 (SO4) 3 + 6H2O
iron hydroxide 3, sulfuric acid, ferrous sulfate 3, water
2Fe (OH) 3 + 6H (+) + 3SO4 (2 -) = 2Fe (3 +) + 3SO4 (2 -) + 6H2O
