Matter is broken down into two main parts: mixtures and pure substances. A pure substance is something that is consistent throughout. This means that in this substance all the atoms or molecules are the same. Elements are a sub-unit of pure substances. All the atoms in elements are identical. They can be paired up to form molecules however the atoms must be the same. Ex. Hydrogen (H2), Nickel (Ni), Iron (Fe) are all elements, and thus would also be pure substances. Compounds are also a sub-unit of pure substances. A compound is made up of one type of molecule and the molecule is made up of different types of atoms. Salt (NaCl) is a compound, as is Water (H2O). Mixtures are collections of more than one type of molecule and/or atom. This can include solutions, such as salt water, suspensions which tend to be cloudy, and mechanical mixtures, such as raisin bran where the parts are readily visible and can be separated.

Various points of distinction between a chemical compound and a mixture are summarized below: Characteristics Pure substance or compound Mixture 1. Composition The elements in a compound are present in definite proportion by weight. The ingredients of a mixture may be present in varying ratio. 2.Homogeneity A compound is always homogeneous. A mixture may be homogeneous (solution) or heterogeneous. 3. Properties A compound has entirely different properties from those of its constituents. Properties of a mixture are of the properties of its constituents. 4. Separation The constituents of a compound cannot be separated by simple separation techniques. The constituents of. a mixture can be separated by simple methods. 5. Energy changes Energy in the form of heat, light or elec­tricity is either evolved or absorbed when a compound is formed. There is generally no energy change when a mixture is formed from its constituents. 6. Volume change At constant temperature and pressure, formation of a compound may involve either no change or large change in volume. At constant temperature and pressure, formation of a mixture involves either very little or no change in volume.

Matter is classified as mixtures and what?

Matter is classified as mixtures and substances. Mixtures are made up of two or more different substances that are physically combined, such as saltwater. Substances consist of only one type of atom or molecule, like elements (e.g. gold) and compounds (e.g. water).


Matter is Classified as mixtures and?

Matter is classified as mixtures and substances. Mixtures are composed of two or more different substances that are physically combined, while substances are pure forms of matter that cannot be separated by physical means. Substances are further divided into elements and compounds.


What are the two main categories matter is classified into?

Matter is classified into two main categories: pure substances and mixtures. Pure substances are further divided into elements and compounds, while mixtures are divided into homogeneous and heterogeneous mixtures.


What is classification of substance?

Substances can be classified as elements, compounds, or mixtures. Elements are made up of only one type of atom, compounds are made up of two or more different elements chemically bonded together, and mixtures are combinations of two or more substances that are not chemically bonded.


Classification of matter according to its composition?

Matter can be classified into elements, compounds, and mixtures based on its composition. Elements are pure substances made up of one type of atom. Compounds are composed of different elements chemically bonded together in fixed ratios. Mixtures are combinations of two or more substances that are physically mixed together but not chemically bonded.


What is a pure substance that can be broken down into smaller substances called?

whyMatter can be broken down into Pure Substances and Mixtures. Mixtures can't be broken down by anything, however Pure Substances break down to Elements and Compounds.The mixtures whether it is homogenous or heterogoneous can NOT be broken down and be observed because it is a chemical change not a physical change


How is matter classified at microscopic level?

Matter is classified at the microscopic level based on its composition and structure. It can be categorized into elements, compounds, and mixtures. Elements are made up of a single type of atom, compounds are composed of different types of atoms chemically bonded together, and mixtures are made up of two or more substances physically combined.


What are the classification of matter according to its composition?

Matter can be classified into elements, compounds, and mixtures based on its composition. Elements are made up of only one type of atom, compounds consist of different elements chemically bonded together, and mixtures are a combination of two or more substances that are not chemically bonded.


What is the overall definition that includes mixtures compounds and elements?

The overall definition that includes mixtures, compounds, and elements is matter. Matter refers to anything that has mass and takes up space. Mixtures are combinations of different substances that can be physically separated, compounds are substances composed of two or more elements chemically bonded, and elements are pure substances composed of only one type of atom.


How many groups can matter be divided into?

Matter can be classified into two main groups: pure substances and mixtures. Pure substances are further divided into elements and compounds, while mixtures can be further categorized into homogeneous and heterogeneous mixtures based on their composition and properties.


Are there more elements or non-elements?

There are more non-elements than elements. Non-elements refer to everything that is not classified as an element, such as compounds, mixtures, and substances that do not fit the definition of an element.


What can be classified as a substance?

A substance can be classified as a form of matter that has a specific chemical composition and properties. This includes elements, compounds, and mixtures. Examples of substances include water (H2O), salt (NaCl), and air (a mixture of gases).
