Chemistry 1.3 CLASSIFICATION OF MATTER Matter can be divided into two main categories: PURE SUBSTANCES and MIXTURES. Matter that has uniform and unchanging composition is called a p_______ s_______. Different atoms from different elements combine in a specific ratios to form a p _______ s_______. An element is a p_______ s________ that is made up of only one type of atom. A compound is a p_______ s__________ that is composed of different types of atoms. Elements and compounds are p_______ s_______. Any material with a definite chemical composition can be called a p_______ s_______. Any material having unique and defining properties is called a p________ s_________. Table salt (NaCl) is an example of a compound of p_______ s_________. Water (H2O) is an example of a compound of p_______ s_________. Sugar (sucrose C12H22O11) is an example of a compound of p_______ s_________. A MIXTURE is a combination of two or more substances that are not chemically united and are not in a specific ratio, one substance to the other. The individual components of a m_______ retain their identity. A mixture can be classified as two types, a HOMOGENEOUS m_______ and a HETEROGENEOUS m_______. HOMOGENEOUS mixtures have uniform composition throughout the m_________. A homogeneous mixture is also called a SOLUTION. A mixture of two or more substances that can not easily be distinguished from one another is called a s_______. Solids, liquids and gases can all create a s_________. Putting milk and chocolate syrup into a blender and turning it on will create a h__________ m__________ , also called a s___________. Melting sugar into hot water will create a h__________ m__________ , also called a s___________. Because the components of iron (Fe) and carbon (C) cannot be easily distinguished, steel is a h___________ m___________. Because you cannot distinguish the tea from the water in which it is dissolved, a cup of hot tea is a h___________ m___________. A HETEROGENEOUS mixture is one in which the individual components do not blend smoothly throughout. A mixture in which individual substances remain distinct is called a h____________ m___________. A mixture that has visibly different substances is said to be h__________. No matter how hard you shake or stir a beaker of water with beach sand added to it, the sand never dissolves in the water. Upon standing, the sand will settle to the bottom of the beaker, illustrating that this is a h__________ m_________. A mixture made up of different substances that remain physically separate is considered h__________. Any combination of substances that does not have uniform composition and properties is a h_________ m__________. Iced tea is a h__________ m__________ because the ice cubes are separate and distinct from the tea. Because the different ingredients of trail mix are easy to identify, trail mix is a h____________ m__________. REVIEW Matter that has uniform and unchanging composition is called a p_______ s__________. A combination of two or more substances that are not chemically united and are not in a specific ratio, one substance to the other is called a m___________. A mixture that has uniform composition throughout is called a h____________ m__________. A mixture in which individual substances remain distinct is called a h_____________ m____________.
