This document discusses the differences between pure substances and mixtures. Pure substances are either elements or compounds, while mixtures contain two or more substances mixed together. Compounds are formed by a chemical change and can be broken down, while elements are simplest forms that cannot be broken down further. Mixtures can be either homogeneous, with substances evenly mixed together like solutions, or heterogeneous with distinct parts like suspensions. Common separation methods for mixtures include distillation, filtration, and evaporation which separate substances based on properties like boiling points or particle size. Chemical changes can be identified by a change in color, production of a gas, or formation of a precipitate.

A pure substance contains only one element or compound and has definite chemical and physical properties, while a mixture contains two or more substances and its properties may vary depending on concentrations. An element cannot be broken down chemically, elements are the basic building blocks of matter, and compounds are made of two or more chemically combined elements. Mixtures can be either homogeneous solutions that are uniform in composition, or heterogeneous mixtures where substances can later be separated as the mixture is not uniform.Matter concept map

No, you do not need to learn the complete periodic table right away. Focus on learning:
- The names and symbols of the most common elements like H, He, C, N, O, F, Na, Mg, Al, Si, P, S, Cl, K, Ca, etc.
- The overall layout and organization of the periodic table. Pay attention to how elements are grouped based on their properties.
- Key trends as you read across or down the periodic table, such as changes in atomic radius, electronegativity, metallic/non-metallic character.
As you study chemistry concepts involving different elements, you will naturally learn more of the periodic table over time. But it'sCLASSIFICATION OF MATTER

The document discusses key concepts related to states of matter, mixtures, and solutions. It defines elements and compounds, and describes homogeneous and heterogeneous mixtures. Solutions are defined as homogeneous mixtures where one substance dissolves in another. Suspensions are mixtures where an insoluble material is mixed with a liquid. Solubility depends on temperature and molecular structure. The pH scale measures the concentration of hydronium and hydroxide ions to indicate if something is acidic or basic, with values below 7 being acidic and above 7 being basic.Ch. 2 classification of matter ppt

Here are brief explanations of the key concepts:
- The composition of an element is fixed because elements are pure substances made of only one type of atom.
- The composition of a compound is also fixed, but compounds contain two or more elements combined in a fixed ratio.
- Properties of mixtures can vary because mixtures are combinations of two or more substances that are not chemically combined. Their compositions are not fixed.
- Mixtures can be classified as solutions, suspensions, or colloids based on whether the mixed substances are uniformly dispersed (solutions), settle over time (suspensions), or are dispersed with particles too small to settle but large enough to scatter light (colloids).

This document discusses the classification of matter. It defines a pure substance as either an element or compound that has a definite and uniform chemical composition and physical properties. Mixtures can be either heterogeneous or homogeneous. A heterogeneous mixture has an uneven texture that is visible, while a homogeneous mixture, or solution, is completely uniform throughout. There are three main types of mixtures: solutions, suspensions, and colloids. A solution is a mixture where one or more substances are uniformly distributed in another substance. A suspension is a mixture where particles are spread through but settle over time. A colloid is between a solution and suspension, with particles that do not settle over time.Classifications of Matter

Matter is anything that occupies space and has mass. It can be classified as elements, compounds, or mixtures. Elements are substances that cannot be decomposed, compounds are formed when two or more elements chemically combine, and mixtures maintain the properties of their components. Matter can exist in solid, liquid, or gas states and sometimes as plasma under special conditions. Its state changes with the addition of energy. A substance undergoes physical changes when its appearance changes but not its composition, and chemical changes when its composition changes through chemical reactions.Chem unit 2 presentation

There are three main types of matter: mixtures, elements, and compounds. Mixtures are two or more substances that are not chemically combined and can be separated physically. Elements are the simplest pure substances that cannot be broken down further. Compounds are pure substances made of two or more elements that can be broken down chemically into simpler substances.What is chemistry

Chemistry is the study of matter and its changes. There are five main branches of chemistry: organic, inorganic, physical, analytical, and biochemistry. The scientific method is used to solve problems through observation, hypothesis, experimentation, and theory development. There are two types of research: basic research seeks knowledge, while applied research attempts to solve problems. Matter can be classified as pure substances or mixtures depending on its uniformity of composition.Science matter powerpoint
- 1. Pure Substances and Mixtures By: S a rah Pomera n tz
- 2. Matter Pure Substances Mixtures Compound Element Homogenous Heterogeneous Mixture Mixture
- 3. Mixture A mixture is two compounds that can be separated by physical means and can maintain it’s physical property.
- 4. Compound A compound is two substances that have been chemically combined and can be separated into simpler substances by chemical means.
- 5. Element Simplest form of a pure substance and cannot be broken down any further and can’t be broken down any further.
- 6. Homogeneous Mixture A homogeneous mixture is where one thing is dissolved in another. E.X: Salt Water, Lemonade, Milk
- 7. Heterogenous Mixture A heterogenous mixture is two substances that are mixed but not combined E.X: Vinegar and Oil, M&M’s
- 8. Colloids A colloid is a homogeneous mixture that have large particles that are not dissolved and are evenly distributed.
- 9. Solution A solution is a homogeneous mixture when one thing is dissolved in the next.
- 11. Distillation A process that separates the substance in a solution (mixture) based on boiling points. E.X: Sulfur and Sodium Chloride
- 12. Filtration A process that separates materials based on the size of the particle
- 13. Evaporation A process used to isolate a solid dissolves in a liquid E.X: Sodium Chloride and Water
- 14. Observing Chemical Properties Chemical Properties can be observed only when the substances in a sample of a matter are changing into different substances.
- 15. Flammability Flammability is a material’s ability to burn in the presence of oxygen
- 16. Reactivity How readily a substance combines chemically with other substances.
- 17. Recognizing Chemical Change There are three ways to recognize chemical change. You can recognize it using the change in color, the production of gas, or the formation of a precipitate.
- 18. Change in Color Is a clue that a chemical change has produced at least one new substance
- 19. Production of Gas The production of gas can be a clue to chemical change
- 20. Formation of a Precipitate Any solid that forms and seperates from a liquid mixture is called a precipitate. A chemical change that alters their structure.
- 21. Is Change Chemical or Physical When matter undergoes a chemical change, the composition of a matter changes. When matter undergoes a physical change, the composition of the matter remains the same.
- 22. Chapter 2 Over view Questions! Why is a element a fixed composition? How can you classify a solution, suspension, or colloid? What are two common separation methods? What are three common types of evidence for chemical change?
