Question

Two students were in Chemistry Class completing an assigned lab experiment. The two students were to mix 5.34g CaCl2 with CuSO4 to make a 6.3L solution

. Complete and balance the reaction with the correct Products:
CaCl2 + CuSO4  ______ + ______

Answer 1

CaCl₂ + CuSO₄ → CaSO₄ + CuCl₂.

Step-by-step explanation:

• It is a replacement reaction, that cations and anions are replaced with each other.

So, it gives CaSO₄ and CuCl₂.

• To balance the reaction, we apply the law of conversation of mass, that the no. of atoms in the reactants side is equal to that in the products side.

So, the balanced reaction is:

CaCl₂ + CuSO₄ → CaSO₄ + CuCl₂.
