To describe the formation of calcium chloride, we need to understand the reaction involved.
1. Reaction: Calcium metal reacts with chlorine gas to form calcium chloride.
2. Chemical Equation: Ca(s) + Cl2(g) → CaCl2(s)
3. Formation Process:
- Calcium, represented as Ca, is a metal that reacts with the diatomic chlorine gas, Cl2.
- During the reaction, one calcium atom combines with two chlorine atoms.
- The calcium loses two electrons to form Ca2+ ions, while the chlorine gains one electron each to form Cl- ions.
- The electrostatic attraction between the Ca2+ and Cl- ions forms ionic bonds, resulting in the formation of solid calcium chloride, CaCl2.
4. Drawing:
[Ca] + [Cl-Cl] → [Ca2+] + 2[Cl-] → CaCl2
5. Explanation of Drawing:
- The initial reactants are calcium (Ca) and chlorine gas (Cl2), represented as [Ca] and [Cl-Cl] respectively.
- After the reaction, calcium loses electrons to become Ca2+ and chlorine gains electrons to become Cl-. This is depicted as [Ca2+] and 2[Cl-].
- The final product, calcium chloride (CaCl2), is represented by the combination of Ca2+ and 2Cl- ions.
By following these steps and understanding the chemical reaction involved, we can visualize the formation of calcium chloride.
