  11. What is density and temp's relationship
    Density is dependent on temperature

    bromine and mercury
  17. 7 diatomic elements
    • I have never found clubs on board: I, H, N, F, Cl, O, Br
    • (F,Cl, Br,I are all halogens)
  18. Metal and non-metal usually make a___ compound

    molecular compound
  20. what charge do metals and nonmetals have
    • metals=cation +

  21. which of the following observation is not a chemical change
    A) converting coal (coal is a form of carbon) to carbon dioxide
    B) converting ion to steel (steel is an alloy of iron).
    C) converting sulfur to acid rain (acid rain contains H2SO4)
    D)converting H to water (H2O)
    B), because alloys are not only mixtures of 2 metals, and do not undergo chemical change.
    (this multiple choice question has been scrambled)
  22. What is the law of conservation of mass:
    Energy can not be created or destroyed, it simply transforms, so the mass of the reactant= the mass of the product.
