- Assigned on 09/15: Classwork: Reading materials for the 2019-20 school year |
Chapter 1. Solve problems and email them to mark.lukin@gmail.com
- Assigned on 09/22:
Read chapter 2, solve problems, email me to mark.lukin@gmail.com
- Assigned on 09/29:
Read Chapter 3 and email me your solutions. (mark.lukin@gmail.com)
- Assigned on 11/3:
Read the section 5 (Oxygen and oxides) and 6 (Oxide, acidic oxides and acids), solve problems and email them to mark.lukin@gmail.com
- Assigned on 11/17:
Read the section 6 and learn the rules on acid naming. Read the section 7 and solve the problen #4. Keep in mind that one mole of any gas occupy 22.4 at normal pressure and room temperature
- Assigned on 12/8:
Read the section #8 (Salts and their reactions), and try to solve homework problems
- Assigned on 01/5:
Read the section 8 in full, especially subsections 8.4-8.5. Prepare to discuss it in class. Solve problems and email them to me.
- Assigned on 01/19:
Make the experiment with tea and red cabbage, as I explained in the class, make photos and email to me.
Read the section 9, subsections: Interrelation between bases and acids.Classification of chemical reactions. Exchange reactions. Solve problems 1-4
- Assigned on 02/2:
Read chapters #9 and #10 in full. Solve the problem #6, chapter 9 and email the solution to me
- Assigned on 02/9:
Re-read about everything that we discussed previously and prepare for a practical test
- Assigned on 02/23:
Prepare for a practice test.
You will be provided with the following solutions:
CuSO4
CaCl2
Ca(NO3)2
KOH
HCl
ZnCl2
ZnSO4
AgNO3
K3PO4
Each bottle is labeled, but every label is placed on a wrong bottle: thus, the AgNO3 label is NOT on the bottle with the AgNO3 solution.
You will have 40 minutes to make needed chemical reactions and decide which bottle contains which chemical.
- Assigned on 03/1:
No homework
- Assigned on 03/8:
Read the section #11 (Classification of elements. Halogens), solve problems and email them to me.
- Assigned on 03/22: Classwork: Classwork&Homework |
Please, read sections 1-8, comment, and send me back the pdf with your comments. Solve problems after each section
- Assigned on 04/19:
Try to do the experiment that we discussed in the class WITHOUT platinum (so far). Phenolphthaleine is available from Amazon: https://www.amazon.com/s?k=phenolphthaleine&link_code=qs&sourceid=Mozilla-search&tag=mozilla-20 , so you can reproduce this experiment at home.
For the beginning, use just copper wires and phenolphthaleine. Try different materials: sugar, vinegar, baking soda, table salt (whatever you can find) and record what you see in each case.
Let's consider that is your homework.
