PRACTICE QUIZZES/TESTS FOR FINAL
- The two below will test your knowledge of section 10.1 and the rest will be questions very similar to the ones you will have.
- Measuring matter with the mole- 5 questions
- Mass and the mole - 5 questions
- Go here and try quizzes for the first two sections: http://glencoe.mheducation.com/sites/007874637x/student_view0/chapter8/
- Go here and try quizzes for sections 1 to 3: http://glencoe.mheducation.com/sites/007874637x/student_view0/chapter7/
- Go hehttp://glencoe.mheducation.com/sites/007874637x/student_view0/chapter4/re and do all 3 section quizzes http://glencoe.mheducation.com/sites/007874637x/student_view0/chapter6/
- Go here and do section quizzes for 2 & 3 http://glencoe.mheducation.com/sites/007874637x/student_view0/chapter4/
Friday February 2
- Balanced equations- need to have the same number of particles on both sides eg. 3 Fe reactants and 3 Fd Products (conservation of matter)
- In combustion O2 gas is converted to CO2 and H20
- signs of chemical reactions: ppt, smell, change in color, bubbles (gas)
- physical vs chemical change
- density units
- Celcius compared to Fahrenheit, more divisions in Fahrenheit. 32 degrees F and 212 degreees F = 0 and 100 degrees Celcius
FRIDAY JANUARY 26
- STUDY GUIDE
- Make sure to know how to do all things in 10.1 (13 & 14 questions) - 1 question written
- when would you use the following conversion factors?
- 1 mole = 6.02 x 10²³ particles (molecules, formula units, atoms are used for "particles" in the text)
- molar mass = (grams per mole) = (g/mol)
- e.g. the molar mass of Oxygen can be found by looking at the periodic table and it is (15.009 g O₂/ mol O℃)
- for the above example a question concerned the amount of oxygen atoms instead of the amount of oxygen molecules (which are O₂) you can see that there are 2 atoms for every 1 molecule of oxygen just as there are 3 atoms for every 1 molecule of water (H₂O), two hydrogen atoms and one oxygen atom equal together 3!
- when would you use the following conversion factors?
- acid/base
- ph scale is 1 to 14 with 1 being acidic and 14 being most basic.
- more H+ ions the more acidic a solution becomes. The more OH- ions a solution has the more basic it becomes.
- Know how to write the formulas if given name
- example (potassium and oxygen are mixed) K=+1 and O=-2 so answer is K₂O
- but if potassium and Nitrogen were mixed then K=+1 but N=-3 instead of -2 so answer is K₃N₂
- Know how to name compounds and molecules if given the formula
- e.g. CO = "Carbon monoxide" while C₂O₃= "dicarbon trioxide"
- Know how to name compound if given the formula (NO₃) containing one of the transition metals
- e.g. If I said "Copper (II) sulfide" then formula would be CuS
- e.g, If I said Copper (I) sulfide then formula would be Cu₂S (copper is a transitional element which means it can have more than one charged state) Copper (I) means Cu⁺ and Copper (II) means Cu² ⁺
- What bonds are stronger (ionic and covalent) while the intermolecular bonds are weaker (hydrogen bonds are strongest of these)
- Know your polyatomic ions as you were supposed to be quizzed on them last week and you would have not passed. So now that you know this it is important to make it next time with a good understanding of them because you will probably be quizzed on them.
- There may be a question about Lewis structures and valence electrons.
- Know the properties of an ionic bond vs a covalent. Which is the compound and which is the molecule? The basic unit of the compound is called the formula unit
- Ionic bonds are a metal/nonmetal bonds that are electric. Know how they match up with each other to cancel out the overall charge.
- The metals are of a positive ionic charge and are called "cations"
- The nonmetals are of a negative ionic charge and are called "anions"
- covalent bonds are between nonmetals and they share electrons to fill their valence electron shell .
- Ionic bonds are a metal/nonmetal bonds that are electric. Know how they match up with each other to cancel out the overall charge.
- Know the periodic trends of growing bigger (The elements increase in size as they go down the rows but decrease in size as they move from left to right. Electronegativity (attractions for electrons) and ionization energy levels are the opposite as they increase from down to up and from left to right.
- You should also know the trends in ionic size (read page 168)
- Know where the different groups are in the periodic table: alkali metals, alkaline earth metals, transition metals, nonmetals, metalloids, the noble gases, the halogens,
- The protons, neutrons and electrons. You must know all their charges and relative sizes to each other and where each is located (in the nucleus? in electron clouds?) You must be able to determine the atomic number, the atomic mass as well as the total charge when comparing different numbers of electrons and protons,
- And know all the names of the elements and symbols for them that you were responsible for knowing on the quiz.
THURSDAY JANUARY 18
- You need to know sections 8.1, 8.2, and 8.4 the best you can and we can go over what you dont get on Friday.
- SKIP 8.3
- Know everything in 9.1, 9.2, and 9.3. (SKIP 9.4 AND 9.5) The polyatomic ions you should memorize would be all of the ones included in the game I showed you. here is the link CHEMISTRY GAMES TO LEARN POLYATOMIC IONS, ACIDS, BASES, ETC...
