1. Define Compound and Its Properties:

A compound is a substance formed when two or more elements chemically bond together in fixed proportions. Properties of compounds include:

Fixed Composition: The elements are combined in specific ratios.

Unique Properties: Compounds have distinct physical and chemical properties that differ from the individual elements (e.g., water is different from hydrogen and oxygen).

Chemical Stability: Compounds are generally stable and require chemical reactions to separate into their constituent elements.

2. Define Mixture and Its Properties:

A mixture is a combination of two or more substances that are not chemically bonded and can be separated by physical means. Properties of mixtures include:

Variable Composition: The proportions of components can vary.

Retained Properties: The individual substances retain their own properties (e.g., in a salad, the lettuce and tomatoes maintain their flavors).

Separation Techniques: Mixtures can be separated using physical methods such as filtration, distillation, or chromatography.

3. Two Major Differences Between Compound and Mixture:

Composition: Compounds have a fixed composition with elements chemically bonded in specific ratios, whereas mixtures have a variable composition with components physically combined.

Properties: Compounds exhibit unique properties that are different from the properties of their constituent elements, while mixtures retain the individual properties of each substance.
