(c) Magnesium is reduced (d) Magnesium is oxidized

Answer 1

Answer:

magnesium is reduced

as per class 10 basis of notes

this is correct answer

Answer 2

Magnesium is reduced is not observed when magnesium ribbon burns with a dazzling Flame in air.

Explanation:

• Dazzling flame burns Magnesium ribbon in air it shows white flame.
• White flame changes it state into a white powder.
• The white powder formed because of the reaction between magnesium and oxide present in the air.
• Magnesium is oxidised and This powder is known as Magnesium oxide.

The equation will be :

$Mg+ \frac{1}{2} O2-> MgO$

The reaction takes place is known as redox reaction.

Hence,

Option (c) Magnesium is reduced is correct.
