Questions: square → CaCl2(s)

Transcript text: $\square \rightarrow \mathrm{CaCl}_{2}(s)$

Solution

Solution Steps

Step 1: Identify the Product and Its Components

The product given in the reaction is calcium chloride, $\mathrm{CaCl}_{2}(s)$ . This compound is a halide, which is formed by the combination of an alkaline earth metal and a halogen.

Step 2: Determine the Alkaline Earth Metal

Calcium ( $\mathrm{Ca}$ ) is an alkaline earth metal. Alkaline earth metals are found in Group 2 of the periodic table and include elements like beryllium, magnesium, calcium, strontium, barium, and radium.

Step 3: Determine the Halogen

Chlorine ( $\mathrm{Cl}$ ) is a halogen. Halogens are found in Group 17 of the periodic table and include elements like fluorine, chlorine, bromine, iodine, and astatine.

Step 4: Write the Balanced Chemical Equation

The reaction involves calcium ( $\mathrm{Ca}$ ) and chlorine ( $\mathrm{Cl}_2$ ) as reactants. The balanced chemical equation for the formation of calcium chloride is:

$\mathrm{Ca}(s) + \mathrm{Cl}_2(g) \rightarrow \mathrm{CaCl}_2(s)$

Final Answer

$\boxed{\mathrm{Ca}(s) + \mathrm{Cl}_2(g) \rightarrow \mathrm{CaCl}_2(s)}$
