I'm sorry, but the chemical equations you provided are incomplete or incorrect. Each chemical equation should have a reactant and a product separated by an arrow indicating the direction of the reaction. Additionally, the chemical formulas should be properly balanced and written using subscripts and superscripts to indicate the number of atoms or ions involved.

Here are some possible balanced chemical equations involving calcium (Ca) and other elements or compounds:

1. Ca(OH)2 + Ca -> 2 CaO + H2O This equation shows the reaction between calcium hydroxide (Ca(OH)2) and calcium metal, which results in the formation of calcium oxide (CaO) and water (H2O).

2. 3 CaS + 2 Al -> Al2S3 + 3 Ca This equation represents the reaction between calcium sulfide (CaS) and aluminum (Al), which produces aluminum sulfide (Al2S3) and calcium metal.

3. 2 CaI2 + Cl2 -> 2 CaCl2 + I2 This equation shows the reaction between calcium iodide (CaI2) and chlorine gas (Cl2), which results in the formation of calcium chloride (CaCl2) and iodine (I2).

4. CaH2 + 2 H2O -> Ca(OH)2 + 2 H2 This equation represents the reaction between calcium hydride (CaH2) and water (H2O), which produces calcium hydroxide (Ca(OH)2) and hydrogen gas (H2).

5. 3 Ca3N2 + 2 Al -> 2 AlN + 9 Ca This equation shows the reaction between calcium nitride (Ca3N2) and aluminum (Al), which results in the formation of aluminum nitride (AlN) and calcium metal.

6. CaO + C -> CaC2 + CO This equation represents the reaction between calcium oxide (CaO) and carbon (C), which produces calcium carbide (CaC2) and carbon monoxide gas (CO).
