Answer 2

The chemical equation you've written appears to be unbalanced. Let's balance it:

Ca(OH)2 + H3PO4 → Ca3(PO4)2 + H2O

First, let's break down the compounds into their individual elements:

• Ca(OH)2: Calcium (Ca), Oxygen (O), Hydrogen (H)
• H3PO4: Hydrogen (H), Phosphorus (P), Oxygen (O)
• Ca3(PO4)2: Calcium (Ca), Phosphorus (P), Oxygen (O)
• H2O: Hydrogen (H), Oxygen (O)

Now, let's balance the equation by making sure the same number of atoms of each element are on both sides:

On the left side, we have:

2 calcium (Ca) atoms 2 hydrogen (H) atoms from Ca(OH)2 3 hydrogen (H) atoms from H3PO4 2 phosphorus (P) atoms from H3PO4 2 oxygen (O) atoms from Ca(OH)2 4 oxygen (O) atoms from H3PO4

On the right side, we have:

3 calcium (Ca) atoms 2 hydrogen (H) atoms from H2O 2 phosphorus (P) atoms from Ca3(PO4)2 10 oxygen (O) atoms from Ca3(PO4)2 and H2O

Now, let's balance the equation:

Ca(OH)2 + 2H3PO4 → Ca3(PO4)2 + 6H2O

Now, we have the same number of each type of atom on both sides of the equation, and it's balanced.
