Make an equation: S element oxide + sodium hydroxide, Na element oxide + sulfuric acid, Calcium carbonate + Hydrochloric acid, Ca hydroxide + phosphoric acid
1) Oxide of the element S + sodium hydroxide – SO3 + 2NaOH = Na2SO4 + H2O;
2) Oxide of the element Na + sulfuric acid – Na2O + H2SO4 = Na2SO4 + H2O;
3) Calcium carbonate + Hydrochloric acid – CaCO3 + HCl = CaCl2 + CO2 + H2O;
4) Ca hydroxide + phosphoric acid – Ca (OH) 2 + H3PO4 = CaHPO4 + 2H2O.
