Balanced Chemical Equation – Solution
CaCO3 + 2HCl → CaCl2 + H2O + CO2
The coefficients show the number of particles (atoms or molecules), and the indices show the number of atoms that make up the molecule. New substances are formed as a result of the rearrangement of the original atoms. As a result of a chemical reaction, atoms of chemical elements do not disappear anywhere and new ones do not appear, their number remains unchanged – this follows from the law of conservation of mass of substances.
Chemical Reaction Information
This is an acid-base reaction (neutralization): CaCO3 is a base, HCl is an acid.
Calcium Carbonate + Hydrogen Chloride = Calcium Chloride + Water + Carbon Dioxide
Substances that react are called starting materials or reactants. The substances that form as a result are called reaction products.
CaCO3 – Calcium carbonate
- Other names: Calcite; aragonite; chalk; Lime (material).
- Appearance: Fine white powder; chalky taste.
HCl – Chlorane, Hydrogen chloride
- Other names: Hydrochloric acid.
- Appearance: Colorless, transparent liquid, fumes in air if concentrated; Colorless gas.
CaCl2 – Calcium chloride
- Other names: Calcium(II) chloride, Calcium dichloride.
- Appearance: White powder, hygroscopic.
H2O – Water, oxidane
- Other names: Water (H2O), Hydrogen oxide, Hydrogen hydroxide.
- Appearance: White crystalline solid, almost colorless liquid with a hint of blue, colorless gas.
- Names: Carbon dioxide
