Answer:

20 g of copper (II) oxide, CuO

Explanation:

The balanced equation for the reaction is given below:

CuO + 2HCl —> CuCl₂ + H₂O

From the balanced equation above,

1 mole of CuO reacted to produce 1 mole of CuCl₂.

Next, we shall determine the number of mole of CuO needed to produce 0.25 mole of CuCl₂. This can be obtained as follow:

From the balanced equation above,

1 mole of CuO reacted to produce 1 mole of CuCl₂.

Therefore, 0.25 mole of CuO will also react to produce 0.25 mole of CuCl₂.

Finally, we shall determine the mass of 0.25 mole of CuO. This can be obtained as follow:

Mole of CuO = 0.25 mole

Molar mass of CuO = 64 + 16

= 80 g/mol

Mass of CuO =?

Mole = mass /Molar mass

0.25 = mass of CuO /80

Cross multiply

Mass of CuO = 0.25 × 80

Mass of CuO = 20 g

Therefore, 20 g of copper (II) oxide, CuO is needed for the reaction.
