Answers
Answer:
yes this is correct.
N means nitric but don't NH
H²O is hydrochloric acid
Answer:
4NH₃ (g) + 3O₂ (g) ⟶ 2N₂ (g) + 6H₂O (g)
Explanation:
NH₃ + O₂ ⟶ N₂ + H₂O
In this reaction, ammonia ( NH₃ ) reacts with oxygen ( O₂ ) to form nitrogen ( N₂ ) and water ( H₂O ).
Atoms in reactants side:
- N = 1
- H = 3
- O = 2
Atoms in products side:
- N = 2
- H = 2
- O = 1
By law of conservation of mass, we know that the number of atoms of each element in reactants side must be equal to number of atoms in products side.
To balance hydrogen atom in both sides, we multiply H₂O by 6 as LCM of 3 and 2 is 6.
NH₃ + O₂ ⟶ N₂ + 6H₂O
Atoms in reactants side:
- N = 1
- H = 3
- O = 2
Atoms in products side:
- N = 2
- H = 12
- O = 6
To balance oxygen atom in reactant side, we multiply O₂ by 3.
NH₃ + 3O₂ ⟶ N₂ + 6H₂O
Atoms in reactants side:
- N = 1
- H = 3
- O = 6
Atoms in products side:
- N = 2
- H = 12
- O = 6
In reactant side, 9 hydrogen atoms are missing. So, we multiply NH₃ by 4 to make hydrogen atoms 12, equal to that of in product side.
4NH₃ + 3O₂ ⟶ N₂ + 6H₂O
Now, in product side 2 nitrogen atoms are missing. To balance it, we multiply N₂ by 2.
4NH₃ (g) + 3O₂ (g) ⟶ 2N₂ (g) + 6H₂O (g)
This is the balanced chemical equation.
