Напишите сокращённые ионные уравнения ; Если какую либо цифру помещаю в [ х ], то она мелкая, например H[2]O. ------------------------------------------------------------------------------------------------------------------------------
1.CuO + 2HNO[3] = Cu(NO[3])[2] + H[2]O
2.K[2]O + 2HCI = 2KCI + H[2]O
3.Fe[2]O[3] + 3H[2]SO[4] = Fe[2](SO[4])[3] + 3H[2]O
4.ZnO + H[2]SO[4] = ZnSO[4] + H[2]O
5. 3Na[2]O + 2H[3]PO[4] = 2Na[3]PO[4] + 3H[2]0
