Which of the following substances does water interact with: CuO, Na, CaO, KOH, F2, SiO2, SO3, NH3, CH4, C2H4, C2H5Cl, Ag, C2H2? Write down the equations of the corresponding reactions.
With sodium – sodium hydroxide:
2Na + 2H2O = 2NaOH + H2.
With calcium oxide – slaked lime:
CaO + H20 = Ca (OH) 2.
With fluorine:
2H2O + 2F2 = 4HF + O2.
With SO3 – sulfuric acid:
H2O + SO3 = H2SO4.
With ammonia – ammonia:
NH3 + H2O = NH4OH.
With acetylene – acetaldehyde:
C2H2 + H2O = CH3COH.
