We are given substances, water, chemical formula H2O, calcium oxide, chemical formula CaO, sodium hydroxide, chemical formula NaOH, sulfuric acid, chemical formula H2SO4, zinc, chemical formula Zn, pentavalent phosphorus oxide, chemical formula P2O5.
Let’s consider the interactions of these substances with each other.
Water and calcium oxide chemically react to form calcium hydroxide, a lime slaking reaction.
H2O + CаO = Cа (OH) 2
Sodium hydroxide reacts with sulfuric acid to form a sodium sulfate salt and release water.
2 NaOH + H2SO4 = Na2SO4 + 2 H2O
Pentavalent phosphorus oxide reacts with water to form phosphoric acid.
P2O5 + 3 H2O = 2 H3PO4.
