Question

…………… was able to show the relationship between oxygen and metal, resulting in rust.

Answer 1

1. Lavoisier was able to show the relationship between oxygen and metal, resulting in rust. He was also able to show the role of oxygen in plant and animal respiration. Lavoisier also showed that water is composed of hydrogen and oxygen.
2. The earliest attempt to classify the elements was made by Lavoisier. He divided the elements into groups of metals and non-metals in order to study their acidic and basic properties.
3. When a metal reacts with oxygen in the presence of moisture, a metal oxide forms. This process is called corrosion, which is a natural process that converts a refined metal into a more chemically stable oxide. The general equation for this reaction is= metal + oxygen → metal oxide.
4. For example, $$\begin{gathered} 4\mathrm{Fe}\left(\mathrm{s}\right)+3{\mathrm{O}}_2\left(\mathrm{g}\right)+2{\mathrm{xH}}_2\mathrm{O}\left(\mathrm{l}\right)\to 2{\mathrm{Fe}}_2{\mathrm{O}}_3.{\mathrm{xH}}_2\mathrm{O}\left(\mathrm{s}\right) \\ \left(\mathrm{rust}\right) \end{gathered}$$

Hence, Lavoisier was able to show the relationship between oxygen and metal, resulting in rust.
