Answer 2

Balancing the Chemical Equation for the Reaction Ca3(PO4)2 + H2SO4 -> CaSO4 + H3PO4

To balance the chemical equation for the reaction Ca3(PO4)2 + H2SO4 -> CaSO4 + H3PO4, we need to ensure that the same number of each type of atom is present on both sides of the equation.

The unbalanced equation is: Ca3(PO4)2 + H2SO4 -> CaSO4 + H3PO4

To balance it, we can follow these steps:

1. Start by counting the number of atoms of each element on both sides of the equation. 2. Adjust the coefficients of the compounds to balance the number of atoms of each element.

Let's proceed with balancing the equation.

Balancing the Equation

1. Counting the atoms: - Calcium (Ca): 3 on the left, 1 on the right - Phosphorus (P): 2 on the left, 1 on the right - Oxygen (O): 8 on the left, 7 on the right - Hydrogen (H): 2 on the left, 3 on the right - Sulfur (S): 1 on the left, 1 on the right

2. Balancing the equation: - We can start by balancing the phosphorus atoms by placing a coefficient of 2 in front of H3PO4. - This gives us: Ca3(PO4)2 + H2SO4 -> CaSO4 + 2H3PO4

Now, let's check if the equation is balanced: - Calcium (Ca): 3 on the left, 3 on the right - Phosphorus (P): 2 on the left, 2 on the right - Oxygen (O): 8 on the left, 8 on the right - Hydrogen (H): 2 on the left, 6 on the right - Sulfur (S): 1 on the left, 1 on the right

The equation is now balanced with the following coefficients: Ca3(PO4)2 + 3H2SO4 -> 3CaSO4 + 2H3PO4

This balanced equation ensures that the same number of each type of atom is present on both sides of the chemical reaction.
