Question

When magnesium is heated over the flame it forms---------------------

Answer 1

Answer:

magnesium oxide

After it burns, it forms a white powder of the magnesium oxide. Magnesium gives up two electrons to oxygen atoms to form this powdery product. This is an exothermic reaction. An exothermic reaction is a term that describes a chemical reaction in which there is a net release of energy (heat)

Explanation:

Answer 2

• It turns into a white powder of magnesium oxide as it burns.
• To make this powdered substance, magnesium gives away two electrons to oxygen atoms.
• This is an example of an exothermic reaction. An exothermic reaction is one in which there is a net release of energy .
• The property demonstrated in this presentation employs magnesium metal to show what occurs when metal combines with oxygen gas found in the air around us.
• Magnesium metal and its alloys are highly combustible in their pure state, whether molten, powdered, or in ribbon form.
• Magnesium metal, when burning or molten, interacts aggressively with water.
