Chemistry- Elements, Compounds and Mixtures

Cards (19)

  • Element
    A substance made from one type of atom
  • Compound
    a substance made from two or more different types of atoms chemically bonded together
  • Mixture
    A substance made from two or more elements. NOT chemically bonded together. Can be seperated
  • Pure
    Only made from one type of substance. Will have one boiling point. Elements and compounds are pure substance
  • Impure
    Made from two or more different types of elements. Will have a variety of different boiling points. Mixtures are impure substances.
  • Molecule
    Group of atoms bonded together, representing the smallest fundamental unit of a chemical compound
  • Chemical formula
    A series of numbers and chemical symbols that represent the number of atoms bonded together in a compound
  • Chemical Equation
    An equation showing chemicals that react together and the new product they form. Always has an arrow between the reactants and products, never an equals sign
  • Reactant
    Found on the left of the arrow in an equation. These are the chemicals that are breaking apart and rearranging their particles
  • Product
    Found on the right of the arrow in an equation. These are the rearranged atoms of the reactants, chemically bonded together to form new products
  • Chromatography
    The method for separating dissolved substances from one another
  • Distillation
    Method for separating the solvent from a solution
  • Filtration
    Method for separating an insoluble solid from a liquid
  • Saturated
    when a solution contains the maximum amount of solute it can
  • Solubility
    The ability for a given substance to dissolve in a solvent
  • Soluble
    A substance that will dissolve
  • Solute
    The dissolved substance in a solution
  • Solution
    A liquid mixture in which a solid (solute) is distributed in a liquid (solvent)
  • Solvent
    liquid in which the solute dissolves to form a solution
