  1. H2O is water and H2O2 is hydrogen peroxide. What is H2O4?
    Drinking.
    Have you heard the one about a chemist who was reading a book about helium?
    He just couldn't put it down.

    Helium walks into a bar,
    The bar tender says "We don't serve noble gasses in here."
    Helium doesn't react.

    Two chemists go into a restaurant.
    The first one says "I think I'll have an H2O."
    The second one says "I think I'll have an H2O too" -- and he died.

    Just double checking if the atomic number is 4 and the atomic mass in 9 that means there is 4 protons and 5 electrons?

      If the atomic number is 4 and the atomic mass is 9, there are 5 neutrons,4 protons and 4 electrons.

    2. are protons and electrons always the same?

      the number of protons in the atom of an element determines its place in the periodic table but i believe the number of protons and electrons are the same

      No,they can be different due to different isotopes of the same element, where the neutron count is different.

      I would assume we are going to need these formulas to answer certain questions throughout the test.

    1. Molarity is moles of solute per kilogram of solvent.
      Molarity is moles of solute per liter of solution.

  12. Can someone remind me how to get the molar mass of something

    1. First you need the correct formula.
      Then figure out the # of atoms of each type from the formula.
      Use your periodic table to figure out how many grams per mole of each type.

      Ex. H2O
      2H=. 2x1=2
      1O= 1x16=16
      H2O =16+2=18g/mole
