Study Guide: Test 1 Chapters 1 -3 VERY IMPORTANT: This test is the most memorization based in Chem1035. You are held responsible for learning many names/symbols, etc. that were not specifically mentioned in class. Furthermore, the test will be proctored and monitored. Any signs of cheating will be submitted to the Honor Court system. Remember that I will never try to trick you. I will always write problems so that you have enough information to solve the problem. If I give you a number in the problem, you will need to use it. If I give you an equation, you will need to use it I will give equations on the front (but you will need to know what the symbols mean.) And if you have questions-ask! If I can tell you info, I will (although the proctors will not answer detailed questions) Furthermore, gauge how long it takes you to solve the homework. I gauge the timing of the test so that it might take the average student about 0.5-1 minutes per point (and you have about 75 minutes for the test) which boils down to 2-3 minutes per question. If you have never truly practiced (by doing LOTS of homework-perhaps more than assigned ARIS) then you may be slow and rushed for time. Look to the front of the test for some additional, helpful information. Such information would include:  Needed constants  Equations symbolically written (like at the end of the chapter)  Conversion factors for metric system-non S.I sytems  Periodic table Do not expect to have the following types of information given to you (on the front of the test or answered by the proctors)  Power of 10 table (you need to memorize this)  Simple conversions (I think if my 5 year old niece should know it, then you should too!)-stuff like minutes in an hour, feet in a yard, that type of thing  Meanings of symbols (you should know these) The test will be taken from the following skill sets. Chapter 1: (This is a good practice for any chapter) Know definitions (bold words): physical, chemical, mixture, solution, Look at the figures (don’t memorize-but be comfortable with information) Look at the tables: (don’t memorize) but pay attention to the units, the relative sizes (what kind of big number vs tiny numbers) Specific Goals are: Furthermore, this test has more memorization than any other test this semester-most of it is given in Tables. I expect you to thoroughly know the following tables Periodic Table:  Know the name of each symbol,  Know periods (properties change gradually) vs groups (chemicals react similarly)  know some of the major divisions (metal, non metal, metalloid),  know some chemicals that react similarly (columnar groups on periodic table-such as noble gasses, halogens, alkali metals, alkaline earth metals, transition metals)  know what the atomic number means (# protons), know what the atomic weight approximately means (protons+neutron) and neutral atoms have the electrons= atomic number  know the “noble gas” rules for making ions. Non metals gain electrons to form an anion such that the number of electrons gained puts you at the nearest noble gas. Metals lose electrons to form an anion such that the number of electrons lost puts you at the nearest noble gas. Know the SI units table (Table 1.2)  Know the symbols for common measurements. Know the Power of 10 table (Table 1.3-it will be given on the 1st test only)  Know the symbols for the prefixes (practice these-they come up repeatedly)  Know how to use the table to create conversion factors- example. 1*10 -3 L = 1 mL (don’t put the power of 10 “upside down”)  Know that if you have multiple units in a conversion you have to make multiple steps: example to go from nm to mm you convert from nm to m, and then use the table again to convert between m and mm) Know the polyatomic ions table (Table 2.6) (memorize it-below are some hints, but there is no substitute for knowing the names)  Polyatomic means many atoms, so polyatomic means more than one atom. The first atom is the root of the name: i.e. (SO3) -2 is sulf___  You can guess the charge based on the 1st atom (works on MOST-not all) o Example: in (SO3) -2 the first atom (S) makes a -2 charge so the whole polyatomic ion would have a -2 charge (SO3) -2  Most polyatomic atoms contain oxygen, the oxygen ending is __te o If the ion has 3 or 4 O atoms, the ending is ate
