Question

Assertion:Burning of Magnesium is an exothermic process. 1
Reason: During the formation of bond between Magnesium and Oxygen a lot of heat is released.

Answer 1

Answer:

assertion and reason  is true.

Explanation:

When the magnesium metal burns it reacts with oxygen found in the air to form Magnesium Oxide. A compound is a material in which atoms of different elements are bonded to one another. Oxygen and magnesium combine in a chemical reaction to form this compound. 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 as well as combination reaction.
