Calcium carbonate decomposes to form calcium oxide and carbon dioxide gas. If 44.5 grams of calcium oxide is produced, how many grams of calcium carbonate had to decomposez?
We need a stoichiometric reaction that represents the decomposition of calcium carbonate:
And thus calcium oxide and calcium carbonate are present in equimolar amounts:
Given the stoichiometry of the reaction, an equimolar quantity of calcium carbonate MUST have been present.
This represents a mass of
In the decomposition reaction, what does the
