What is a physical property?

A physical property is a characteristic of a substance that can be observed or measured without changing the substance's chemical composition. These properties include factors such as color, shape, density, and thermal conductivity, among others.

A physical property is a characteristic of a substance that can be observed or measured without changing its chemical composition.

Yes, that is correct. Physical properties include characteristics such as color, hardness, density, melting point, boiling point, and electrical conductivity. These properties help us identify and classify substances based on their unique traits, without altering their chemical structure.

Give an example of a chemical property.

The ability of iron to rust when exposed to oxygen and water is an example of a chemical property. Rusting is a chemical reaction in which iron reacts with oxygen to form iron oxide, demonstrating a change in the substance's chemical composition rather than just a physical change.

Flammability is an example of a chemical property, as it describes the ability of a substance to undergo a chemical reaction and burn.

Flammability is indeed an example of a chemical property as it pertains to the behavior of a substance in relation to fire or combustion, indicating its potential to undergo a chemical reaction and burn when exposed to heat or flame. This property is intrinsic to the specific chemical composition of the substance and can be used to differentiate it from other materials based on its reactivity with fire.

How is a mixture different from a pure substance?

A mixture is a combination of two or more substances that are physically mixed together but retain their individual properties, whereas a pure substance is a single type of material that has a constant composition and distinct set of properties. Pure substances have consistent melting and boiling points, while mixtures can have variable properties depending on the ratios of the substances present.

A mixture is a combination of two or more substances that are physically blended together, while a pure substance consists of only one type of substance and cannot be separated by physical means.

In contrast to pure substances that consist of only one type of substance, mixtures are combinations of two or more substances that are physically blended together and can be separated by physical means.

What are the two main types of mixtures?

The two main types of mixtures are homogeneous mixtures, where the components are evenly distributed and difficult to distinguish, and heterogeneous mixtures, where the components are not evenly distributed and can be easily identified.

The two main types of mixtures are homogeneous mixtures (uniform composition) and heterogeneous mixtures (non-uniform composition).

Homogeneous mixtures are uniform in composition, where the components are evenly distributed and not visually distinguishable, while heterogeneous mixtures have a non-uniform composition with distinct phases.

Define an element.

An element is a substance that consists of atoms having the same number of protons in their atomic nuclei, thereby defining a specific chemical identity. Each element is represented by a unique symbol, such as H for hydrogen or Fe for iron, which is found on the periodic table of elements. Elements cannot be chemically broken down into simpler substances and are the building blocks of all matter in the universe.

An element is a pure substance that consists of only one type of atom. It cannot be broken down into simpler substances by chemical means.

An element is a pure substance made up of atoms of only one type and cannot be further broken down into simpler substances by chemical reactions.
