Answer 1

White wine is a homogeneous mixture; mercury is an element; ranch-style salad dressing is a heterogeneous mixture; and table sugar (sucrose) is a compound. These classifications help understand the properties and composition of substances in chemistry.

Step-by-step explanation:

To identify each substance as a compound, an element, a heterogeneous mixture, or a homogeneous mixture (solution), the characteristics of each must be considered:

• a. White wine is a homogeneous mixture, also known as a solution. It is a blend of water, alcohol, and various other compounds that are uniformly distributed.
• b. Mercury is an element. It is a pure chemical substance consisting of one type of atom, and it is listed on the periodic table.
• c. Ranch-style salad dressing is a heterogeneous mixture. It contains ingredients that are not uniformly distributed and may separate upon standing.
• d. Table sugar (sucrose) is a compound. Sucrose is made of carbon, hydrogen, and oxygen in a fixed ratio, and its composition is consistent throughout.

Exercise 1.3.1, 1.2.1, and 1.5.2 are all focused on the same task of classification of substances. This concept is a fundamental aspect of chemistry as it helps to understand the composition and properties of materials around us.
