1. Combustion of sulfur with the release of sulfur dioxide.
S + O2 = SO2 (oxide).
2. Reaction of sulfur oxide with water and nitric acid to form nitric oxide and sulfuric acid.
SO2 (oxide) + H2O (oxide) + HNO3 (oxygen-containing acid) = NO (oxide) + H2SO4 (oxygen-containing acid).
3. Reaction of sulfuric acid with barium chloride to form barium sulfate and hydrochloric acid.
H2SO4 (oxygen-containing acid) + BaCl2 (salt) = BaSO4 (salt) + 2HCl (anoxic acid).

1. Combustion of phosphorus in oxygen to form phosphorus (V) oxide.
4P + 5O2 = P4O10 (P2O5) (oxide).
2. Formation of phosphoric acid in the reaction of phosphorus oxide with water.
P2O5 (oxide) + 3H2O (oxide) = 2H3PO4 (oxygenated acid).
3. Reaction of phosphoric acid with magnesium hydroxide to form magnesium sulfate and water.
H3PO4 (oxygen-containing acid) + Mg (OH) 2 (base) = Mg3 (PO4) 2 (salt) + H2O (oxide).
