Many things go into the study of chemistry. This includes models witch study phenomena involving elements. These models can include ball & stick, statements, or equations. Some key terms from chapter one are matter, composition, and properties. Matter is anything that has mass and volume. Composition is the types and amountsof simpler substances within. Properties are characteristics identifying a substance. Properties can be physical or chemical. II. Composition of matterThe periodic table consists elements. These elements can be made into compounds which consist of two types of atoms. These compounds can be expressed by a chemical formula. Thereare also compounds that are called mixtures. These mixtures can’t be expressed by a formula. They consist of at least two atoms. III. Pure SubstancesThese notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute.Pure substances are compounds. They consist of two or more different elements. They have a constant composition and break down chemically. Elements consist of the same atoms. They can’t break down chemically. They are all the substances listed on the periodic table. IV. Mixtures Mixtures can be broken down physically. They can filter and evaporate. They consist of two or more substances and have a variable composition. V. Mixtures vs. Pure SubstancesChemistry consists of mostly mixtures. Reactions deal with mostly pure substances. VI. PropertiesThere are several different types of properties. There are physical, extensive, and intensive. Physical properties are observed without doing chemical reactions. These physical properties can be color, melting point, and boiling point. Extensive properties depend on the amount of matter. These properties include mass and volume. Intensive properties do not depend on matter. There properties include density, temperature, and
