Question

Почему CaO+Ba(OH)2 не будут реагировать?

Answer 1

я считаю что из за того что Кальций имеет активность ниже чем барий, он попросту не сможет провести реакцию обмена, так же как неактивные металлы с кислотами

Answer 2

CaO and Ba(OH)2 will not react because they do not have a common ion or a driving force for a chemical reaction. In order for a reaction to occur, there needs to be a driving force such as the formation of a precipitate, the production of a gas, or the transfer of electrons. In this case, CaO (calcium oxide) is a basic oxide and Ba(OH)2 (barium hydroxide) is a strong base. When these two compounds are mixed together, they will not undergo a reaction because they do not have any common ions or a driving force for a reaction to occur.
