1) По химическим свойствам.

2) Амфотермым оксидам соответствуют амфотерные гидроксиды, которые сочетают свойства оснований и кислот.

3)

Окисление простых и сложных веществ  S+O2=SO2

Разложение гидроксидов  Ca(OH)2 =t= CaO + H2O

Разложение карбонатов и других солей  CaCO3 =t= CaO + CO2

Взаимодействие металла с другим оксидом 2K + CO2 = K2O + СO2

4) Оксид и название элемента

5) оксид калия, оксид азота III, оксид меди II, оксид фосфора III, оксид меди I

 

Как то так=)
