Explanation:
<span>Among the choices provided, the answer is letter C, CuSO4(aq) + Fe(s) → FeSO4(aq) + Cu(s) since Iron(Fe) is higher up on the action graph and is, along these lines, more responsive than Copper(Cu). Because of this, Iron can supplant Copper in that substance equation. </span>
Chlorine + aluminium bromide --> aluminium chloride + bromine
Chlorine replaces bromide in AlBr3
3Cl2 + 2AlBr3 ---> 2AlCl3 + 3Br2
Hope it helped!
