3. Соединения
А7.Укажите формулы бинарных соединений
4. H2O, K2O, AlCl3
А8.Укажите продукты, которые образуются в результате реакции взаимодействия фосфата бария и сульфата калия
формально ответ вот такой, но фактически эта реакция вряд ли пойдёт!)
2. Сульфат бария, фосфат калия
А9.Укажите ряд сильных электролитов
1. AlCl3, H2SO4, HNO3
А10.Из предложенных уравнений реакций выберите то, которое можно записать в ионном виде
1. K2SO4 + BaCl2 =BaSO4 + 2KCl
3. H2SO4 + Mg(OH)2 = Mg SO4+ 2H20
(тут два варианта подходят)
