Question

Balance the following equations:
Ca(OH)2(aq) + H2PO2 (aq) → H20(l) + Ca(PO)

Answer 1

The student's question on how to balance a chemical equation involving calcium hydroxide and phosphoric acid producing water and calcium phosphate is answered by providing the balanced chemical equation: 3Ca(OH)2 + 2H3PO4 → Ca3(PO4)2 + 6H2O.

Step-by-step explanation:

The task at hand is to balance the chemical equation between calcium hydroxide, Ca(OH)2, and phosphoric acid, H3PO4, to produce water, H2O, and calcium phosphate, Ca3(PO4)2. The balanced chemical equation looks like this:

1. Write down the unbalanced equation:
   Ca(OH)2(aq) + H3PO4(aq) → H2O(l) + Ca3(PO4)2(s)
2. Identify how many of each atom are present on each side of the equation.
3. Adjust the coefficients to balance the numbers of atoms on each side. In this case:
   3Ca(OH)2 + 2H3PO4 → Ca3(PO4)2 + 6H2O

To solve the equation, three moles of calcium hydroxide react with two moles of phosphoric acid to produce one mole of calcium phosphate and six moles of water.
