Question

When metals react with oxygen ,it forms​

Answer 1

Answer:

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.

Explanation:

When a metal reacts with oxygen, a metal oxide forms.

The general equation for this reaction is: metal + oxygen → metal oxide.

Some metals will react with oxygen when they burn. These reactions are called combustion reactions. Two examples of combustion reactions are:

Iron reacts with oxygen to form iron oxide:

4 Fe + 3 O2 → 2 Fe2O3

Magnesium reacts with oxygen to form magnesium oxide:

2 Mg + O2 → 2 MgO

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.

Rust can be prevented by coating iron surfaces with paint, or with rust-resistant metals such as chromium or zinc.

Answer 2

$\huge {\red {\sf {\underline {\underline{Answer}}}:-}}$

Metals react with oxygen to form metal oxides which are basic in nature. Most of the metal form basic oxide.

Example:

Sodium + Oxygen → Sodium Oxide

Zinc + Oxygen → Zinc Oxide

Magnesium + Oxygen → Magnesium Oxide
