Balancing Chemical Equation:

Ni N2O4 = Ni(NO3)2 NO

Before balancing, we need to check whether the given equation is balanced or not. The above equation is not balanced. It can be balanced by following the steps below.

Step 1: Write the unbalanced equation.

Ni N2O4 = Ni(NO3)2 NO

Step 2: Count the number of atoms of each element on both sides of the equation.

Reactants: Ni - 1, N - 2, O - 4
Products: Ni - 1, N - 2, O - 6, N - 1

Step 3: Balance the equation by adding coefficients to the reactants and products.

Ni + N2O4 = Ni(NO3)2 + 2NO

Now, let's check if the equation is balanced.

Reactants: Ni - 1, N - 2, O - 4
Products: Ni - 1, N - 2, O - 4, N - 2

The equation is now balanced.

Explanation:

A chemical equation represents a chemical reaction. In a chemical equation, the reactants are written on the left-hand side, and the products are written on the right-hand side. The coefficients in front of the chemical formulas indicate the number of moles of each substance involved in the reaction.

To balance a chemical equation, we need to make sure that the number of atoms of each element is the same on both sides of the equation. We can do this by adding coefficients to the chemical formulas. The coefficients must be the smallest possible integers that will balance the equation.

In the given equation, we have one nickel atom, two nitrogen atoms, and four oxygen atoms on the left-hand side. On the right-hand side, we have one nickel atom, two nitrogen atoms, four oxygen atoms, and one nitrogen atom. In order to balance the equation, we need to add coefficients to the reactants and products.

We can start by adding a coefficient of 2 in front of NO on the right-hand side to balance the number of nitrogen atoms. This gives us:

Ni + N2O4 = Ni(NO3)2 + 2NO

Now, we have two nitrogen atoms on both sides of the equation. However, we still need to balance the number of oxygen atoms. We can do this by adding a coefficient of 2 in front of Ni(NO3)2 on the right-hand side. This gives us:

Ni + N2O4 = 2Ni(NO3)2 + 2NO

Now, we have four oxygen atoms on both sides of the equation, and the equation is balanced.

In conclusion, balancing a chemical equation is an important step in understanding chemical reactions. It helps us to determine the stoichiometry of the reaction and to predict the products of the reaction.

Ni + 2N2O4 = Ni(NO3)2 + 2NO
