Textbook Problem

# You place 2.56 g of CaCO3 in a beaker containing 250. mL of 0.125 M HCl. When the reaction has ceased, does any calcium carbonate remain? What mass of CaCl2 can be produced?CaCO3(s) + 2 HCl(aq) → CaCl2(aq) + CO2(g) + H2O(ℓ)

Interpretation Introduction

Interpretation:

The mass of CaCl2 produced in the given reaction has to be determined.

Concept introduction:

• For chemical reaction balanced chemical reaction equation written in accordance with the Law of conservation of mass.
• Law of conservation of mass states that for a reaction total mass of the reactant and product must be equal.
• The molar mass of an element or compound is the mass in grams of 1 mole of that substance, and it is expressed in the unit of grams per mol (g/mol).
• Stoichiometric factor is a relationship between reactant and product which is obtained from the balanced chemical equation for a particular reaction.
• Amountof substance=Concentrationofsubstance×volumeofthesubstance
• Massofthesubstance=Amountofthesubstance×molarmassofthesubstance
Explanation

Balanced chemical equation for the given reaction is,

â€‚Â CaCO3(s)â€‰+â€‰2HCl(aq)â€‰â†’â€‰CaCl2(aq)â€‰+CO2(g)â€‰+H2O(l)

Amount of HCl can be calculated from its volume and concentration as follows,

â€‚Â Amountâ€‰ofâ€‰HCl =â€‰CHClâ€‰Ã—â€‰VHCl =â€‰0.125molLâ€‰Ã—â€‰0.25â€‰L =â€‰0.03125â€‰molâ€‰HCl

Using the stoichiometric factor the amount of CaCO3 required to proceed this reaction can be calculated as follows,

â€‚Â 0.03125â€‰molâ€‰HClÃ—â€‰1â€‰molâ€‰CaCO32â€‰molâ€‰â€‰HClâ€‰=â€‰0
