Answer 2

Balancing the Chemical Equation

The given chemical equation is: P2O5 + H2O = CaO + H2O

To balance this equation, we can follow these steps:

1. Write down the unbalanced equation: P2O5 + H2O = CaO + H2O 2. Count the number of atoms of each element on both sides of the equation. 3. Balance the equation by adding coefficients to the compounds.

Balancing the Equation Step by Step

The unbalanced equation is: P2O5 + H2O = CaO + H2O

Step 1: Count the number of atoms of each element on both sides of the equation.

- Phosphorus (P): 2 on the left, 0 on the right - Oxygen (O): 5 on the left, 2 on the right - Hydrogen (H): 2 on the left, 2 on the right - Calcium (Ca): 0 on the left, 1 on the right

Step 2: Balance the equation by adding coefficients to the compounds.

To balance the equation, we can add a coefficient of 5 in front of H2O on the left side and a coefficient of 2 in front of CaO on the right side.

The balanced equation is: P2O5 + 5H2O = 2CaO + 5H2O

Identifying the Products and Reaction Type

The products of the balanced reaction are: - P2O5 + 5H2O = 2CaO + 5H2O

The type of reaction is a double displacement reaction.

Conclusion

The balanced chemical equation is: P2O5 + 5H2O = 2CaO + 5H2O. The reaction type is a double displacement reaction.
