Question

10 grams of calcium carbonate (CaCO3) produces 3.8 grams of carbon dioxide (CO2) and 6.2 grams of calcium oxide (CaO). Represent this reaction in terms of law of conservation of mass.

Answer 1

Respuesta:

According to the law of mass conversation,

reagent mass = mass of products

Thus,

10g (CaCO3) = 3.8g (CO2) + 6.2g (CaO)

10g (CaCO3) = (3.8g + 6.2g) × (CO2 + CaO)

10gCaCO3 = 10gCaCO3
