Question

Heated copper oxide suffers a lose in weight of C.64 g when carbon monoxide is passe
no carbon monoxide is left after the reaction, the volume occupied by the gas at STP is
(a) 448 ml
(b) 896 mL
(c) 560 mL
(d) 280 mL​

Answer 1

As carbon monoxide is a strong reducing agent , it will reduce copper (II) oxide to copper.It will make carbon dioxide by combining with oxygen.

so,the copper oxide suffers a lose in weight of weight.

I think the right answer may be (a) 448 ml

I am not sure about the right answer.
