NH3 + O2 → NO + H2O, Balance the Equation.
Making both sides of the reaction, the reactants and the products, equal in the number of atoms per element is the ultimate goal of balancing chemical equations. This is due to the fundamental principle of the conservation of mass, according to which matter cannot be created or destroyed. The steps to the balanced equation the NH3 + O2 → NO + H2O are as follows:
Step 1: Given chemical equation is
NH3 + O2 → NO + H2O
Step 2: The procedure used to balance the equation
The following method is the conventional way to balance chemical equations:
- Initial comparison should be made between the total number of atoms of each element on the reactant and product sides.
- To molecules containing an element with differing atom counts on the reactant and product sides, add stoichiometric factors.
- Each side's atom count must be balanced by the coefficient.
- The hydrogen and oxygen stoichiometric coefficients are often given last.
- By dividing the total number of atoms of an element present in 1 molecule of the species by the stoichiometric coefficient, one can determine the number of atoms of that element in a given species.
- Repeat this procedure until there are an equal number of atoms of each reactive element on both the reactant and product sides.
Step 3: Balancing the given chemical equation
The given chemical equation is:
NH3 + O2→ NO + H2O
Reactant side:
- 1 Nitrogen atom
- 3 Hydrogen atoms
- 2 Oxygen atoms
Product side:
- 1 Nitrogen atom
- 2 Hydrogen atoms
- 2 Oxygen atoms
First, the atoms of hydrogen are balanced. After being balanced, the equation is: 2NH3 + O2 → NO + 3H2O
Atoms of nitrogen are then balanced. After being balanced, the equation is:2NH3 + O2 → 2NO + 3H2O
The oxygen atoms are balanced at this point. After being balanced, the equation is: 2NH3 + 5/2 O2 → 2NO + 3H2O
The updated equation is: 2NH3 + 5/2 O2→ 2NO + 3H2O
Reactant side:
- 2 Nitrogen atom
- 6 Hydrogen atoms
- 5 Oxygen atoms
Product side:
- 2 Nitrogen atom
- 6 Hydrogen atoms
- 5 Oxygen atoms
The equation is balanced because there are an equal number of all the atoms of the reacting components on both the reactant and product sides.
Hence, the balanced equation is 2NH3 (g) + 5/2 O2 (g) → 2NO (g) + 3H2O (l)
Summary:
Balance the following equation: NH3 + O2 → NO + H2O
The balanced chemical equation of NH3 + O2 → NO + H2Ois 2NH3 (g) + 5/2 O2 (g) → 2NO (g) + 3H2O (l). The equation can be balanced by making the atoms equal on both sides of the reaction. Because there are an equal number of all the atoms from the reaction components on both the reactant and product sides, the equation is balanced.
