Question

please give the answer​

Answer 1

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.

Metals react with oxygen to form metallic oxides. These metallic oxides are basic because they react with water to form bases. On the other hand, nonmetals react with oxygen to form nonmetallic oxides. These oxides differ from metallic oxides because they are acidic in nature.

Answer 2

1. When a metal react with oxygen, a metal form oxide. The general equation is metal + oxygen ------> metal oxide. Rust is the form of iron oxide. it forms slowly when iron exposed in air.
2. Metals react with oxygen to form metallic oxides. These metallic oxides are basic because they react with water to form bases. Non metals react with oxygen to form non metallic oxides. These oxides differ from metallic oxides because they are acidic in nature.
