How to Write Equations for Genetic Series

To write equations for genetic series, you need to understand the reactions involved and the products formed at each step. Here is a breakdown of the given genetic series:

1. Ca → CaO 2. CaO → Ca(OH)2 3. Ca(OH)2 → Ca3(PO4)2

Let's go through each step and write the balanced chemical equations:

1. Ca → CaO - This reaction involves the conversion of calcium (Ca) to calcium oxide (CaO). - The balanced equation for this reaction is: Ca → CaO.

2. CaO + H2O → Ca(OH)2 - This reaction involves the reaction of calcium oxide (CaO) with water (H2O) to form calcium hydroxide (Ca(OH)2). - The balanced equation for this reaction is: CaO + H2O → Ca(OH)2.

3. 3Ca(OH)2 + 2H3PO4 → Ca3(PO4)2 + 6H2O - This reaction involves the reaction of calcium hydroxide (Ca(OH)2) with phosphoric acid (H3PO4) to form calcium phosphate (Ca3(PO4)2) and water (H2O). - The balanced equation for this reaction is: 3Ca(OH)2 + 2H3PO4 → Ca3(PO4)2 + 6H2O.

Please note that the equation you provided at the beginning, "1.2 Ca + O2 → 2 CaO," is not part of the given genetic series. However, it represents the reaction between calcium (Ca) and oxygen (O2) to form calcium oxide (CaO).

I hope this helps! Let me know if you have any further questions.
