I have a few questions, that I hope you guys will be able to help with. 1. Suppose you have two metals, A and B, and the solutions of their ions, A+ and B+, Metal B is more active than metal A. Write the spontaneous redox reaction for this situation. (I know redox reactions are reactions in which metals oxidize and reduce, but what does this question want to know?) 2.) Which of the following are redox reactions? a.) 2Na + 2H2O ---> 2NaOH + H2 b.) SO2 + H2O ---> H2SO4 3.) Why are liquids and solids referred to as condensed phases? The only thing I can think of for this is that their atoms/molecules are closer together than gas, which are far apart. 4.) Describe each phase of matter on the molecular level with respect to the amount of order and energy present. What exactly is this question asking?? 5.) All of the following are solids at room temperature. Classify them as molecular, ionic, network, or metallic. a.) potassium, melting point = 64*C b.) red phosphorus, mp = 590*C c.) Boron triiodide, mp = 50*C My guesses: A.) Metallic B.) Molecular C.) Boron Triiodide (Can anyone confirm or direct me?) 6.) Describe each phase of matter on the molecular level with respect to the amount of ENERGY present. (Just energy this time, not order). What exactly is this question asking? Can anyone tell me how I can tell, or what I need to do, in order to know what they're classifed as. Thanks for all the help guys. If you don't necessarily want to give me the answers, that is fine, but please lead me in the right direct or provide a source of some sort. Unfortunately for me, most of these questions don't have explicit answers in the book. Like for example, in answer to #5, the book defines ionic molecular solids as solids "represented by sucrose". Not a very good definition if you ask me.... Thanks for all the help in advance!
