Answer:
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.

The correct option is FLUORINE AND COPPER.
An ionic compound is usually formed by the combination of a metal and a non metal, the metal usually act as an electron donor while the non metal act as an electron acceptor. Thus, in ionic compounds, there is total transfer of electrons from the metal to the non metal. In the question given here, copper is the metal while the fluorine is the non metal.<span />
