Question

If 88 grams of carbon dioxide is released when 200 grams of limestone is heated, how much calcium oxide is produced in this reaction?

Answer 1

Answer:

hope it helps ,,if so please mark me brainliest!!!!! tyvm!!!!

Explanation:

Law of conservation of mass states that mass can neither be created nor be destroyed but it can only be transformed from one form to another form.

This also means that total mass on the reactant side must be equal to the total mass on the product side.

The chemical equation for the decomposition of limestone follows:

Let the mass of calcium oxide be 'x' grams

We are given:

Mass of carbon dioxide = 88 grams

Mass of calcium carbonate = 200 grams

Total mass on reactant side = 200 g

Total mass on product side = 88 + x

So, by applying law of conservation of mass, we get:

The mass of calcium oxide that would be produced is 112 grams.
