Question

Декальцинированные кости – это кости, лишённые кальция. Подтвердите это через молекулярное и ионное уравнение реакции между карбонатом кальция и соляной кислотой.

Answer 1

Ответ:

1. CaCO₃ + 2HCl → CaCl₂ + CO₂ + H₂O ↑ ( молекулярное уравнение )

2. CaCO₃ + 2H⁺ + 2Cl⁻ → Ca²⁺ + 2Cl⁻ + CO₂ + H₂O ( ионное уравнение )

3. CaCO₃ + 2H⁺ → Ca²⁺ + H₂O + CO₂ ( краткое ионное уравнение )

Объяснение:

Answer 2

Decalcified Bones

Decalcified bones are bones that have been stripped of their calcium content. This process is often used in scientific research and medical procedures to study specific aspects of bone structure and composition.

Molecular and Ionic Equation for the Reaction Between Calcium Carbonate and Hydrochloric Acid

The reaction between calcium carbonate (CaCO3) and hydrochloric acid (HCl) can be represented by the following molecular and ionic equations:

Molecular Equation: ``` CaCO3 + 2HCl -> CaCl2 + H2O + CO2 ```

Ionic Equation: ``` CaCO3 + 2H+ + 2Cl- -> Ca2+ + 2Cl- + H2O + CO2 ```

In this reaction, calcium carbonate reacts with hydrochloric acid to produce calcium chloride, water, and carbon dioxide. The ionic equation shows the dissociation of the compounds into their respective ions.

The reaction demonstrates the removal of calcium from calcium carbonate, supporting the concept of decalcification.
