Which of the substances whose formulas are given below reacts sulfuric acid a) diluted b) concentrated .. F, Fe (OH) 3, SO2, C, Cao, Cu, Na2CO3 write the reaction equations
A) Diluted sulfuric acid.
3H2SO4 + 2Fe (OH) 3 = Fe2 (SO4) 3 + 6H2O
H2SO4 + CaO = CaSO4 + H2O
H2SO4 + Na2CO3 = Na2SO4 + H2O + CO2
B) Concentrated sulfuric acid.
2H2SO4 + Cu = CuSO4 + 2H2O + SO2
