I don't know the answer of 4 but of 5and6
5).However, this has one big problem. For the redox reaction to occur, the ions must be mobile, but copper (II) oxide is very insoluble in water. ... Whenhydrogen gas is passed over copper oxide, copper oxide is reduced tocopper and hydrogen gets oxidized to H2O.
6).There are variety of ways by which fishes survive winters.
But first of all you need to understand that water bodies rarely freeze completely. Water freezes outside to inside, so even in the coldest winters there is liquid water available to the marines.
Also these fishes have millions of years of evolutionary abilities that help them to survive the cold winters.
