Question

SOMEONE PLS HELP ME ITS URGENT

Answer 1

Answer:

copper is less reactive than iron

Explanation:

=>According to the reactivity series of metals copper is the least reactive metal thus is displaced by iron

Answer 2

If copper is heated with iron oxide there is no obvious reaction because

copper is less reactive than iron.

On a reactivity chart, copper is far below iron. This makes it impossible for a replacement reaction to occur, so the equation doesn't change.

I hope I helped!
