Answer 1

Это легко просто Н20 перилей в NO у тебя получится окислитель а потом сама подумаешь как определить

Answer 2

Balancing the Chemical Equation Using the Electron Balance Method

To balance the chemical equation using the electron balance method, we need to ensure that the number of atoms of each element is the same on both sides of the equation and that the total charge is balanced.

The unbalanced chemical equation is: HNO3 + FeO → Fe(NO3)3 + NO + H2O

First, let's assign oxidation numbers to each element in the equation: - In HNO3, hydrogen has an oxidation number of +1, nitrogen has an oxidation number of +5, and oxygen has an oxidation number of -2. - In FeO, iron has an oxidation number of +2 and oxygen has an oxidation number of -2. - In Fe(NO3)3, iron has an oxidation number of +3, nitrogen has an oxidation number of +5, and oxygen has an oxidation number of -2. - In NO, nitrogen has an oxidation number of +2 and oxygen has an oxidation number of -2. - In H2O, hydrogen has an oxidation number of +1 and oxygen has an oxidation number of -2.

Balancing the Equation Step by Step

1. Balance the atoms of each element: - There are 1 nitrogen atom on the left side and 3 nitrogen atoms on the right side. We can balance the nitrogen atoms by placing a coefficient of 2 in front of HNO3: 2HNO3 + FeO → Fe(NO3)3 + NO + H2O - Now, there are 6 oxygen atoms on the left side and 9 oxygen atoms on the right side. We can balance the oxygen atoms by placing a coefficient of 3 in front of H2O: 2HNO3 + FeO → Fe(NO3)3 + NO + 3H2O - The hydrogen and iron atoms are already balanced.

2. Balance the charges using the electron balance method: - The total charge on the left side is 2(+1) + 3(-2) = -4. - The total charge on the right side is 3(+3) + 1(-2) = +7. - To balance the charges, we need to add electrons to the left side to make the total charge equal to +7.

3. Determine the oxidizing and reducing agents: - The oxidizing agent is the substance that gets reduced, while the reducing agent is the substance that gets oxidized. - In this reaction, FeO is the reducing agent because it undergoes oxidation (loses electrons), and HNO3 is the oxidizing agent because it undergoes reduction (gains electrons).

Final Balanced Equation and Identified Agents

The balanced chemical equation using the electron balance method is: 2HNO3 + 6FeO → 2Fe(NO3)3 + 3NO + 3H2O

The reducing agent is FeO, and the oxidizing agent is HNO3.
