Final answer:
An element is made of one type of matter and cannot be physically separated. Examples include white wine as a homogeneous mixture, mercury as an element, ranch-style salad dressing as a heterogeneous mixture, and table sugar as a compound.
Step-by-step explanation:
The substance that is made from only one type of matter and cannot be separated by physical methods is an element. Elements are pure substances that consist of a single type of atom and cannot be broken down into simpler substances by physical means. In contrast, a compound is composed of two or more different types of atoms chemically bonded together, a mixture is a combination of two or more substances that can be separated by physical means, and a solution is a homogeneous mixture of two or more substances.
Therefore, when identifying substances:
- White wine is a homogeneous mixture (solution).
- Mercury is an element.
- Ranch-style salad dressing is a heterogeneous mixture.
- Table sugar (sucrose) is a compound.
