When calcium carbonate is added to hydrochloric acid, calcium chloride, carbon dioxide, and water are produced. CaCO3 ( s ) + 2 HCl ( aq ) ⟶ CaCl2 ( aq ) + H 2 O ( l ) + CO 2 ( g ) How many grams of calcium chloride will be produced when 30.0 g of calcium carbonate is combined with 10.0 g of hydrochloric acid

The mass of produced is, 15.2 grams.

Explanation : Given,

Mass of = 30.0 g

Mass of = 10.0 g

Molar mass of = 100 g/mol

Molar mass of = 36.5 g/mol

First we have to calculate the moles of and .

and,

Now we have to calculate the limiting and excess reagent.

The balanced chemical equation is:

From the balanced reaction we conclude that

As, 2 mole of react with 1 mole of

So, 0.274 moles of react with moles of

From this we conclude that, is an excess reagent because the given moles are greater than the required moles and is a limiting reagent and it limits the formation of product.

Now we have to calculate the moles of

From the reaction, we conclude that

As, 2 mole of react to give 1 mole of

So, 0.274 mole of react to give mole of

Now we have to calculate the mass of

Molar mass of = 110.98 g/mole

Therefore, the mass of produced is, 15.2 grams.
