Answer 2

Balancing the Chemical Equation H2 + P → PH3

To balance the chemical equation H2 + P → PH3, 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: H2 + P → PH3

Balancing the Equation Step by Step

1. Balancing Hydrogen (H): - There are 2 hydrogen atoms on the left side and 3 on the right side. To balance the hydrogen atoms, we can multiply H2 by 2 on the left side. - The equation becomes: 2H2 + P → PH3

2. Balancing Phosphorus (P): - There is 1 phosphorus atom on the right side and 1 on the left side, so phosphorus is already balanced.

Now, the balanced chemical equation is: 2H2 + P → 2PH3

This balanced equation ensures that the law of conservation of mass is obeyed, with the same number of each type of atom on both sides of the equation.
