Ответ:
Oxidation of ammonia
Explanation:
Chemical equation:
NH₃ + O₂ → NO + H₂O
Balanced chemical equation:
4NH₃ + 5O₂ → 4NO + 6H₂O
The given reaction shows the oxidation ammonia. When oxygen react with ammonia it form nitrogen monoxide and water vapors. Nitrogen monoxide decomposes in air.
It can be seen that the given reaction also follow the law of conservation of mass. There are four nitrogen, ten oxygen and twelve hydrogen atoms on both side of equation.
According to the law of conservation mass, mass can neither be created nor destroyed in a chemical equation.
This law was given by french chemist Antoine Lavoisier in 1789. According to this law mass of reactant and mass of product must be equal, because masses are not created or destroyed in a chemical reaction.
Ответ:
Explanation:
According to the Bronsted-Lowry conjugate acid-base theory, an acid is defined as a substance which looses donates protons and thus forming conjugate base and a base is defined as a substance which accepts protons and thus forming conjugate acid.
For the given chemical equation:
Here,
is loosing a proton, thus it is considered as an acid and after losing a proton, it forms
which is a conjugate base.
And,
is gaining a proton, thus it is considered as a base and after gaining a proton, it forms
which is a conjugate acid.
Hence, the correct answer is D.
