Dec 18: Make a big summary sheet for your test next day!

Use a big 11 by 17 piece of paper and make a big summary sheet explaining how Bohr diagrams work and also Lewis diagrams.  Explain how to calculate atomic mass!  Use all the vocab words in your two worksheets handed out.  Make it creative, make it beautiful and colourful.  Explain how to draw the Lewis structure of ATOMS vs IONS.  When you are done, put your name on your summary sheet.  You will be given a mark out of 5 for your efforts today.

And try out these problems below:

What's on our test?

Test date:        Day 2 November  29
                        Day 1  November 30, 2018


You will have a periodic table.
1.  20 questions on Naming formula and writing names:    
a.  monatomic     NaCl,      CaCl2
b.  polyatomic     (NH4)2SO4
c.  covalent        CO

2.  20 marks on acid base neutralization equations. 
3.  20 marks on balancing equations
4.  Challenging questions:  10 marks. 
I will give you a word equation.  You convert that to formula equation, and then balance it.

20 Multiple choice questions on Acids, Bases and indicators and our labs. See our worksheets on acid and base.

ex. What colour does phenylpthalein turn for base?  pink
What colour does litmus paper turn for acid?  red
What colour does universal indicator turn for base?  blue

What happens when you put a burning splint to Oxygen?  to Hydrogen?

Naming acids practice

Today we reviewed naming acids and I asked you to write  "...ide" acids and    "...ite " acids and also    "...ate" acids. also you did an exercise in naming acids last block.  Now you can do the naming acids practice on page 18 in the Chemistry practice sheet Here is the Chemistry practice sheet key.
