Answer 2

Balanced Equation for the Reaction between CaCO3 and HCl

The balanced equation for the reaction between calcium carbonate (CaCO3) and hydrochloric acid (HCl) can be written as follows:

CaCO3 + 2HCl → CaCl2 + H2O + CO2

In this reaction, calcium carbonate reacts with hydrochloric acid to produce calcium chloride, water, and carbon dioxide. The coefficients in front of each compound indicate the number of molecules or moles involved in the reaction.

Let's break down the equation and explain each component:

- CaCO3: This is the chemical formula for calcium carbonate, which is a white, crystalline solid commonly found in rocks and shells. - HCl: This is the chemical formula for hydrochloric acid, a strong acid commonly used in laboratories and industries. - CaCl2: This is the chemical formula for calcium chloride, a white, crystalline solid that is often used as a drying agent or de-icer. - H2O: This is the chemical formula for water, a compound composed of hydrogen and oxygen atoms. - CO2: This is the chemical formula for carbon dioxide, a colorless gas that is produced during the combustion of fossil fuels and by various biological processes.

The balanced equation ensures that the number of atoms of each element is the same on both sides of the equation, indicating a conservation of mass.

Explanation of the Balanced Equation

The balanced equation shows that one molecule of calcium carbonate reacts with two molecules of hydrochloric acid. This reaction results in the formation of one molecule of calcium chloride, one molecule of water, and one molecule of carbon dioxide.

The coefficients in front of each compound indicate the stoichiometric ratio between the reactants and products. In this case, the coefficient of 1 in front of CaCO3 indicates that one molecule of calcium carbonate is involved in the reaction. The coefficient of 2 in front of HCl indicates that two molecules of hydrochloric acid are required for the reaction to occur.

Similarly, the coefficient of 1 in front of CaCl2, H2O, and CO2 indicates that one molecule of each compound is produced as a result of the reaction.

Verification of the Balanced Equation

The balanced equation provided above is based on the information obtained from search results. However, it is always a good practice to verify the information from reliable sources. Unfortunately, the search results did not provide specific sources that could be cited for verification.

Please note that the balanced equation may vary depending on the reaction conditions, such as temperature and pressure. It is always recommended to consult reliable chemistry textbooks or reputable online sources for further verification and detailed explanations.
