Question

Carbon dioxide is added to 112g of calcium oxide. The product formed is
calcium carbonate. Calculate the mass of carbon dioxide used.​

Answer 1

Answer:

The reaction taking place is:

CO₂+CaO→CaCO₃

Let the mass of CO₂ is xg.

According to the law of conservation of mass, the mass of reactants is equal to the mass of products.

Therefore,

⇒ x + 112g = 220g

⇒ x = 220g – 112g

⇒ x = 108g

Thus, the mass of carbon dioxide is 108g.
