Which of the listed substances will interact with water: Ca, Zn, Cu, Na2O, CO2, MnO, Zn (OH) 2, HNO3. Write the reaction equations. Which of these substances react with sodium hydroxide?
With water:
Ca + 2H2O = Ca (OH) 2 + H2
Na2O + H2O = 2NaOH
CO2 + H2O = H2CO3
With sodium hydroxide:
Zn + 2NaOH + 2H2O = Na2 [Zn (OH) 4] + H2
2NaOH + CO2 = Na2CO3 + H2O
Zn (OH) 2 + 2NaOH = Na2 [Zn (OH) 4]
NaOH + HNO3 = NaNO3 + H2O
