Explanation:

All molecules have a definite mass and size that are dependent on the atoms from which the molecule is made. The mass is equal to the sum of the masses of all the individual atoms in the molecular structure.

Answer 2

CHARACTERISTICS + EXPLANATION:-

• All molecules have a definite mass and size that are dependent on the atoms from which the molecule is made. The mass is equal to the sum of the masses of all the individual atoms in the molecular structure. The size is not only dependent on the atomic components of the molecule, but also on the arrangement of the atoms within the molecule and how tightly they are joined together.

• Much of the research in the field of chemistry today involves the formation of new substances by trying to change atoms within a molecule or the arrangement of the same atoms. This latter is a particularly important area when the arrangement of the atoms is changed from what is called a right-handed molecule to a left-handed molecule or vice-versa. Molecules such as these behave as they do because of their shape, much like gloves fit either the right or the left hand because of their shape. Some of the current research on new fat-free commercial products, such as ice-cream or cooking oil, involves right- or left-handed versions of the original fat molecules. These mirror-images of the original molecules cannot be absorbed or used by the body because of the different shape of the molecule. Yet because they are often so similar, enough of the original properties of the fat remain intact to make it useful as a substitute. So far, the taste and their inability to withstand high temperatures in cooking are problematic.
