Question

Magnesium ribbon on burning in air produces:

• A. magnesium oxide, water and light
• B. magnesium oxide and heat
• C. magnesium oxide, heat and light
• D. magnesium oxide, water and heat

Answer 1

The correct option is C magnesium oxide, heat and light

When a piece of magnesium ribbon is ignited, light and heat are produced.

Magnesium reacts with oxygen to form a compound called magnesium oxide.

The reaction is as follows:

$2Mg+O_2\to 2MgO+\text{heat}+\text{light}$

Hence, the correct option is $\text{C}$
