Question

Salt water a mixture because it has 2 or more substances (compounds and molecules) that are physically mixed together, but they are not chemically bonded. The parts can be separated.

a) True
b) False

Answer 1

The statement is true; salt water is a homogeneous mixture or a solution where salt and water are combined but not chemically bonded, and their individual properties are retained. The components can be separated by physical means.

Step-by-step explanation:

The statement that salt water is a homogeneous mixture because it has two or more substances—salt and water—that are physically mixed together but not chemically bonded is true. Salt water is considered a solution, which is a type of homogeneous mixture where the composition is uniform throughout. Ordinary table salt, known as sodium chloride (NaCl), and water (H₂O) can be mixed in varying ratios to create salt water with different levels of salinity. Despite being thoroughly mixed to the point that the salt is evenly distributed, the constituents retain their individual properties and the mixture's composition can vary. Furthermore, the components of a mixture, such as salt water, can be separated into their pure substances through physical means, unlike compounds which require a chemical process for separation.
