Answer 2

Balancing the Chemical Equation

The given chemical equation is: P + HIO3 + H2O = H3PO4 + HI.

To balance this chemical equation, we can follow these steps:

1. Balance the atoms of each element one at a time. 2. Start by balancing the least common atom or the atom that appears in the fewest reactants and products.

Balancing the Equation Step by Step

1. Balance Phosphorus (P): - There is 1 P on the left side and 1 P on the right side. Phosphorus is already balanced.

2. Balance Iodine (I): - There is 1 I in HIO3 and 1 I in HI on the left side, and 1 I in H3PO4 on the right side. - To balance I, we can add a coefficient of 5 in front of HI on the right side.

3. Balance Hydrogen (H): - There are 3 H in HIO3 and 1 H in H2O on the left side, and 3 H in H3PO4 and 1 H in HI on the right side. - To balance H, we can add a coefficient of 3 in front of H2O on the left side.

4. Balance Oxygen (O): - There are 3 O in HIO3 and 1 O in H2O on the left side, and 4 O in H3PO4 on the right side. - To balance O, we can add a coefficient of 2 in front of HIO3 on the left side.

Balanced Chemical Equation

The balanced chemical equation is: P + 5HIO3 + 3H2O = H3PO4 + 5HI

Identifying the Oxidizing and Reducing Agents

In the given reaction, the substance that undergoes oxidation is the reducing agent, and the substance that undergoes reduction is the oxidizing agent.

- Oxidizing Agent: The substance that gets reduced is the oxidizing agent. - Reducing Agent: The substance that gets oxidized is the reducing agent.

In the balanced equation P + 5HIO3 + 3H2O = H3PO4 + 5HI, P is the reducing agent, and HIO3 is the oxidizing agent.

This information is based on the chemical properties and the changes in oxidation states of the elements involved in the reaction.
