Question

Cu+o2=????????????????​

Answer 1

2Cu+O2=2CuO

ОВР:

2| Cu - 2e -> Cu(+2) - восстановитель, окисление

1| O2 + 4e -> 2O(-2) - окислитель, восстановление

Answer 2

The chemical equation you've provided is:

Cu + O2 → ?????

This equation represents a reaction between copper (Cu) and oxygen (O2). When copper reacts with oxygen, it undergoes a redox reaction to form copper oxide (CuO). The balanced chemical equation for this reaction is:

2 Cu + O2 → 2 CuO

In this balanced equation, two moles of copper (Cu) react with one mole of oxygen (O2) to produce two moles of copper oxide (CuO).
