>> >> //A pure substance has a constant, defined composition and cannot be separated into simpler substances by physical means. There are two types of pure substances, elements and compounds.// >> >> //Elements are pure substances that are made of only one type of atom. The periodic table is a table containing all elements.// >> //Compounds are pure substances that are made of more than one type of atom, and can be decomposed or broken down into its elements by chemical means.// >> >> //A mixture is composed of more than one element and / or compound. Different mixtures of the same substances can have different compositions (i.e., a mixture of water and sodium chloride may be 80% water and 20% sodium chloride, or 20% water and 80% sodium chloride.) There are two types of mixtures, homogeneous and heterogeneous.// >> >> //A homogeneous mixture has the same composition of elements and / or compounds throughout. If you observed a homogeneous mixture under a microscope, you would see that the particles of various components are evenly distributed. A homogeneous mixture is also called a solution.// >> //A heterogeneous mixture has different regions or areas with different compositions and properties. The substances in a heterogeneous mixture are not evenly distributed.// >> >> Identify each of the following as an element, compound, homogeneous mixture or heterogeneous mixture and explain why! >> Mercury, table salt, pure water, coffee, vinegar, air, 14K gold, vegetable soup, concrete, the ocean, wood and steel.
