The idea of a metathesis reaction may be very abstract to you at this point, but we'll see real live metathesis reactions in the next couple of chapters. If you're bored because this is so easy, you can move on. If you're still bewildered, here are a few more problems to work on. You should also be able to make up your own problems at this point; just pick any two first names and any two last names from Table 7-1, matching each first name to a last name to form a compound. For example:
A: (NH4)2SO4(aq) + Ca(OH)2(aq) = 2 NH4OH(aq) + CaSO4(s)
A: No. Calcium carbonate is not soluble in water.
A: 2 AgNO3(aq) + Ca(OH)2(aq) = 2 AgOH(s)) + Ca(NO3)2(aq)
A: Pb(CH3COO)2(aq) + Na2S(aq) = PbS(s) + 2 NaCH3COO(aq)
A: No. Both reactants and both products are soluble in water.
When you can solve these problems without consulting the tables, you should be able to predict the outcome of about half the reactions in this book. Your notebook for this project may omit the "Observations" section, as no manipulation of materials is involved in this project. Include any examples you worked in your notebook along with a flawless metathesis quiz. Also include your analysis of the relative toxicities of caffeine, sodium chloride, sucrose, and sodium cyanide.
