Image result for Write a note on reaction of metals with oxygen and acids​

When a metal reacts with oxygen, a metal oxide forms. The general equation for this reaction is: metal + oxygen → metal oxide. Rust is a form of iron oxide and it forms slowly when iron is exposed to air. Iron can be transformed to steel (an alloy), which is more resistant to rust.

Explanation:

Answer 2

Answer:

Most metals form oxides with the oxygen in a -2 oxidation state. As a general rule, metal oxides are basic and nonmetal oxides are acidic. Basicity of an oxide increases with increasing ionic (metallic) character. ... Oxygen also forms covalent oxides with non-metals, that react with water to form acidic solutions.
