Question

MgO + Cu ➡️ CuO+ Mg Is it possible to have this reaction?????

Answer 1

$\large\bf\underline{Given:-}$

Reaction :- MgO + Cu ---> CuO + Mg

$\large\bf\underline {To \: find:-}$

• is it possible or not

$\huge\bf\underline{Answer:-}$

• MgO + Cu ➡️ CuO+ Mg

According to reactivity series Mg is more reactive then Cu .So Cu can not displace Mg . it's not possible .

So this reaction is wrong.

here,

• Cu = copper
• Mg = magnesium
• O = oxygen

Reactivity series :-

In Reactivity series metals are placed in order of their reactivity from highest reactive metal to lowest reactive metal.
