Answer to Problem 5A
Correct answer :
The correct answer is option (C) a chemical reaction
Explanation of Solution
Explanation/justification for the correct answer :
Option (C) a chemical reaction. A chemical reaction is the process by which atoms or groups of atoms in substances are reorganized into different substances.
Explanation for incorrect answer :
Option (A) a covalent bond. Covalent bonds are the chemical bond that forms when electrons are shared. It is a type of chemical bond through which most of compounds in living organisms are held together. So, this is an incorrect option.
Option (B) a physical property. The physical properties of matter are any properties that can be interpreted or observed without altering the sample's chemical composition. There is no involvement of chemical reaction. So, this is an incorrect answer.
Option (D) van der Waals forces. Van der Waals forces is the attractions between molecules where molecules come together, the attractive forces between these positive and negative regions pull on the molecules and hold together. So, this is an incorrect answer.
