  1. Write the (a) balanced equation for the formation of liquidwater from hydrogen and oxygen gas, and use it to explain thefollowing terms: (b) chemical reaction, (c)reactant, (d) product.



  1. Balance the following equations:

    1. C + O2 → CO

    2. CO + O2 → CO2

    3. Na + H2O → H2 + NaOH

    4. Zn + HCl → ZnCl2 + H2

    5. NaOH + H2SO4 → H2O + Na2SO4

    6. NH3 + CuO → Cu + N2 + H2O



  1. Calculate the mass in grams of iodine (I2) that will reactcompletely with 20.4 g of aluminum (Al) to form aluminum iodide(AlI3).


  1. The annual production of sulfur dioxide from burning coal andfossil fuels, auto exhaust, and other sources is about 26 milliontons. The equation for the reaction is

    S(s) + O2(g) → SO2(g)
