| December 11, 2020 | education
Mg (OH) 2 – base, H2SO4 – acid. as a result of the interaction, salt and water are formed.
Mg (OH) 2 + H2SO4 = MgSO4 + 2H2O
exchange reaction, because on the left and right sides there are two complex substances.
CaO + Co2 = CaCO3
unification reaction, because one compound substance on the right side of the equation.
SO3 – acidic oxide, NaOH – base. the result is salt and water
SO3 + 2NaOH = Na2SO2 + H20
