8.0 g of an element X react with an excess of copper (ll) tetraoxosulphate (lV) solution to deposit 21.3 g of copper. The correct equation for the reaction is?
(Cu = 64).
(Cu = 64).
-
A.
X(s) + CuSO4(aq) → Cu(s) + XSO4(aq) -
B.
X(s) + 2CuSO4(aq) → 2Cu(s) + X(SO4)2(aq) -
C.
2X(s) + CuSO4(aq) → Cu(s) + X2SO4(aq) -
D.
2X(s) + 3CuSO4(aq) → 3Cu(s) + X2(SO4)3(aq)
