Question

Magnesium metal burns with a bright white light . At the end of the reaction , white magnesium oxide powder is produced . Suggest why magnesium is often found in fireworks . Your answer should include a word equation .​

Answer 1

The element magnesium is often in fireworks because it burns with bright white light. It adds white sparks and hence, improves the overall brilliance of a firework.

Properties of Magnesium

• Magnesium metal and its alloys are explosive in nature. They are highly flammable in pure form, powder form, or ribbon form
• Magnesium reacts violently with water
• When magnesium metal is burned it reacts with the oxygen present in the air. Magnesium and oxygen react with each other to form magnesium oxide which is a white powder. Magnesium gives its 2 electrons to the oxygen to form this powdered product.

The reaction is as follows:

                        $2Mg (s) + O_2 (g) \rightarrow 2MgO(s) + energy$

The reaction is exothermic in nature.

• It can also reduce water to H₂ gas

                        $Mg(s)+ 2H_2O \rightarrow Mg(OH)_2(s) + H_2 (g)$

• Magnesium reacts with carbon dioxide to form carbon

                        $Mg(s)+CO_2 \rightarrow 2MgO(s)+ C(s)$

As magnesium is highly flammable and burns with white bright light, hence it is used in fireworks to improve its overall experience.
