Concept explainers
Interpretation:
Formation of Magnesium oxide by the reaction between magnesium and explosive oxygen, wrong statement for this reaction is to be determined.
Concept introduction:
When the metal reacts with the oxygen, they form metal oxides, which are found in powdery form. Magnesium reacts with explosive oxygen, an exothermic reaction. In an exothermic reaction, the reactants are highly reactive and formed a product with energy loss.

Answer to Problem 9STP
Correct Answer: The correct option is (d).
Explanation of Solution
Reason for correct option: In a
Hence, is a correct option.
Reasons for incorrect options:
Option (a), mass of magnesium and the mass of oxygen is equal to the mass of magnesium oxide, by the law of conservation. Hence, this is an incorrect option.
Option (c) There is the formation of a new product as an oxide in a chemical reaction. Hence, this is an incorrect option.
Option (d) The formed product is an example of metal oxide which is categorized as a compound, the compound is formed with a combination of two or more different elements. Hence, this is an incorrect option.
