Question

Calculate the amount of calcium oxide formed when 500g of calcium is heated CaCO3 = Cao + CO2

Answer 1

Answer:

280 grams

Explanation:

The reaction is   CaCO3 → CaO + CO2 

So, One part of Calcium carbonate on heating gives one part of CaO 

Since, 1 part has 100g mass, so 500g means 5 parts of calcium carbonate which will yield 5 parts of CaO   

Mass of CaO obtained = Molar Mass x 5 = 56 x 5 = 280g
