Chemistry 11

Today we reviewed the Solutions Unit by looking at solubilities of polar and non-polar solutes and solvents.  We did the lab:  16A Polar and Non-polar solutes and solvents.   Do all questions #1-5 at the end of the lab.  No conclusion or follow-up questions.

Some answers to selected Unit 6 Solutions Review Assignment:
2) Solvent is water and solute is salt.
3) Polar solutes and ionic solutes will dissolve in polar solvents, non-polar solutes will dissolve in non-polar solvents.

4a) polar solvent= water             c) a non-polar solute = iodine crystals          e) ionic solute = salt

5b) (NH4)3PO4 -------3NH4+ + PO4-3
6b) H2SO4 + H2O -----------H3O+ + HSO4
assume that only one H leaves the acid each time 
7a) [Na+]= 2 x 0.25 M = 0.50 M  [CO3-2] = 0.25 M

8) Two kinds of double replacement reactions are precipitation reactions and acid/base neutralizations

9 and 10 a) 
Molecular:  Na2SO4(aq)  + Pb(NO3)2(aq) -----------PbSO4(s) +  2NaNO3(aq)
 
Total ionic:   2Na+(aq) + SO4-2(aq) + Pb+2(aq) + 2NO3-(aq) ---------PbSO4(s)  +  2Na+ + 2NO3 (aq)
  

Net ionic:  Pb+2(aq) + SO4-2(aq) ---------PbSO4(s)

12) b is a acid       c and e are bases      d and f are neither  

14) ionic solutes will conduct electricity in solution so if you know that the solute is ionic then you know that the solution formed with this solute 

15) [NaCl] = 0.00085 M                    17) Final concentration = 0.13 M

19) 75.0 mL of 2.00 M HCl         21) 0.93 M
 
23) 22.8 g of NaOH

Sunday 7 May 2017

Chemistry 11

BIG UNIT 5 Review Assignment.  Answers to selected questions.

1.  Definitions:  You are on your own!  Make sure you know the difference between polar and non-polar covalent bonds as we didn't go over these in detail.

3.  In any energy level:  electrons are added in the following order:  s, p, d and f.

4a)  Protons=86      electrons=86       neutrons=136

4c)  Protons=92       electrons=92      neutrons=142

4e)  Protons=27        electrons=24      neutrons=631

5a) [Ar]4s23d10

5c) [Xe]6s24f145d106p2

h)  Mn+2= start with Mn=25 electrons.  [Ar]4s23d5        Take off 2 electrons.   So  it becomes [Ar]3d5   (electrons are removed from energy level 4 first).

7)  Masses are the periodic table are not whole numbers since the mass represents the average atomic mass of ALL the isotopes of that element.

8a)  Across a period on the table, atomic radius decreases since electrons are being added to the same energy level.   Protons are also added as you go across a period.  The attraction between protons and electrons increases as you go across a period, so the atoms "shrink" in towards the center.

9b) Down a group on the periodic table, ionization energy decreases since energy levels are being added with each new group.   Electrons are getting further from the nucleus and therefore getting easier to remove.

10)  We will discuss this one in class.

11a)  Rb has a larger radius than I since electrons are added to the same energy level as you move across.   It has more electrons and more protons pulling them in.

12a) Ne has greater ionization energy than Ar.  Ne has outer electrons which have a greater pull towards the nucleus.

13a) C= greater electronegativity.  Pull of its electrons is greater since it has less energy levels than Si.

14a)  P is more reactive than As.  P has greater attraction for electrons therefore can pull off electrons more easily from another element.

15) valence electrons are the most important in bond forming.

16)  We will go over some of these.

17a) non-polar covalent bond       17c) ionic bond          17e) covalent bond (non polar)

Today we took notes on what happens to the atomic radius, electronegativity, ionization energy, and reactivity as you go across a period (row) and down a group (column) on the periodic table.

All the trends can be explained by whether you are adding electrons to the same energy level or whether you are adding a whole new energy level. 

Turn in your graphing assignment with three graphs as well as lab 10A.
