Здравствуйте.
1)Что получается при взаимодействии концентрированной азотной кислоты с оксидом меди2
2)Где можно посмотреть свойства веществ, что с чем реагирует, можт кто знает ссылку и еще что.
Спасибо.

Здравствуйте, Перл-Харбор!
1. Думаю, по аналогии с реакцией расписанной вот тут:
http://www.tyappu.narod.ru/azot.html получится набор следующих веществ:
HNO3 + CuO -> Cu(NO3)2 + NO2 + H20 (надо только коэффициенты расставить)
2. Вот тут есть данные насчет того, что с чем реагирует (18.10):

Здравствуйте, Перл-Харбор!
не согласен с Grigory, вряд ли будет разложение кислоты и выделение NO2, разве что нагревать сильно, но тогда это уже будет скорее разложение соли.
Вы не указали условия, поэтому считаю что нагревания нет.
оксид меди 2 - это основной оксид, ему соответствует основание Cu(OH)2.
медь находится в степени окисления +2, её ещё можно окислить до степени окисления +3, но надо очень жёсткие условия, считаем что это не наш случай. Поэтому азотная кислота будет с ней реагировать просто как с оксидом, а не окислительно-восстановительной реацией.
будет так:
2*HNO3 + CuO = Cu(NO3)2 + H2O.
Насчёт ссылок- достаньте учёбник по химии.
