Question

When a magnesium is heated, it burns in air with a dazzling white flame to form a white powder .What it called? ​

Answer 1

It is magnesium Oxide MgO2

Answer 2

• When a magnesium is heated, it burns in air with a dazzling white flame to form a white powder called Magnesium oxide.

• Magnesium + oxygen → Magnesium oxide.

• The burning of magnesium in air to form magnesium oxide is an example of a chemical reaction . In this chemical reaction there are two reactants ' magnesium and oxygen ' but only one product ' magnesium oxide '. The properties of the product magnesium oxide are entirely different from those of the reactants magnesium and oxygen.

Balanced Equation –

`\purple{\bf{2Mg + O_2 = 2MgO}}`

Physical states –

• Magnesium → Mg ( In Solid State)

• Oxygen →
  `\sf{O_2}` ( Gaseous State)

• Magnesium Oxide → MgO ( In Solid State Or White powder)
