Question

carbon dioxide is added to 112g of calcium oxide .the product gormed s 200g of calcium carbonate. calculate the mass of carbon dioxide used . which law of chemical combination Will govern your answer​

Answer 1

Answer:

88g of CO2.

Law of conservation of mass governs the reaction.

Explanation:

Please refer the attachment.

Hope this may help.

Good luck.

Answer 2

Mass of calcium oxide = 112g

Mass of carbon dioxide = x

Mass of calcium carbonate = 200g

Mass of reactants = Mass of products

Mass of calcium oxide + Mass of carbon dioxide = Mass of calcium carbonate

112 + x = 200

x = 200-112

x = 88

Mass of carbon dioxide = 88g

Law of conservation of mass is governed here
