  3. Describe two ways that atoms may combine with other atoms.
  4. Distinguish between simple and complex carbohydrates.
  5. What is the relationship between matter and elements?
  1. a Synthesis: when 2 or more atoms, ions, or molecules bond to form a more complex structure A+B->AB
    Decomposition: bonds of a reactant molecule break to form simpler molecules, atoms, or ions AB->A+B
    Exchange: parts of 2 different types of molecular trade positions as bonds are broken and new are formed AB + CD-> AD+ BC
    Reversible: product or products can change back to reactant or reactants A+B<-> AB
  2. b DNA: molecules store the information for protein synthesis.
    RNA: molecules use this information to construct specific protein molecules.
  3. c All matter is composed of fundamental substances.
  4. d Two atoms of hydrogen can combine with one atom of oxygen to produce a molecule of the compound water.
    Atoms of the same element combine, they produce molecules of that element.
  5. e Simple: sugars include monosaccharaides, disaccharides; straight chains or rings.
    Complex: polysaccharides are built of simple carbohydrates made of many bonded glucose molecules chains of sugars, cant digest.
