Answer: Option (A) is the correct answer.

Explanation:

When there is a change in chemical bonding of atoms between one or more compounds then it results in the formation of new compounds. This is known as chemical change.

For example, AgNO_{3}(aq) + NaCl(aq) \rightarrow AgCl(s) + NaNO_{3}(aq) is a chemical change as there occurs change in identity and properties of the reactants.

Chemical changes can cause change in color, evolution of bubbles, and formation of precipitate.

Thus, we can conclude that the statement both the identity and the properties of a substance change best describes what happens during a chemical change.

A sample of the chiral molecule limonene is 62% enantiopure. what percentage of each enantiomer is present? what is the percent
ikadub [295]

The mixture contains 62 % one isomer and 38 % the enantiomer.

Let’s say that the mixture contains 62 % of the (<em>R</em>)-isomer.

Then % (<em>S</em>) = 100 % -62 % = 38 %

ee = %  (<em>R</em>) - % (<em>S</em>) = 62 % -38 % = 24 %
