Today we completed a chapter 6 quiz on the periodic table. We also reviewed ions and started chapter 7. Specifically, an overview of putting atoms together: ionic compounds and molecular/covalent compounds.
Please complete the counting atoms questions below:
Today, we explored more on Bohr-Rutherford and drawing diagrams for neutral atoms. Please complete the sheet on drawing the first 20 neutral atoms and their standard notation. Also, read text page 236-239 #3,5,6,8
Today we reviewed the Atomic Theories and looked at the standard notation for elements on the periodic table and drawing Bohr-Rutherford Diagrams.
Please complete the standard notation worksheet and the atomic theory review sheet.
Quiz on chapter 6 on Wednesday.
Today, we looked at periodic table and the specific families and patterns we may see.
It is your job to make notes on the Atomic Theory. You have the sheet to guide you along in what needs to be accounted for in summarizing your information.
Please have the following complete for Friday:
Tomorrow we will be concluding our Physical and Chemical Changes formal lab.
Here are some review questions on density tonight:
- What is the density of CO gas if 0.196 g occupies a volume of 100 ml?
2. A block of wood 3 cm on each side has a mass of 27 g. What is the density of the block? (Hint, don’t forget to find the volume of the wood.)
- An irregularly shaped stone was lowered into a graduated cylinder holding a volume of water equal to 2 ml. The height of the water rose to 7 ml. If the mass of the stone was 25 g, what was its density?
- A 10.0 cm3 sample of copper has a mass of 89.6 g. What is the density of copper?
- Silver has a density of 10.5 grams/cm3 and gold has a density of
19.3 g/cm3. Which would have the greater mass, 5cm3 of silver or 5cm3 of gold?
- Five mL of ethanol has a mass of 3.9 g, and 5.0 mL of benzene has a mass of 44 g. Which liquid is denser?
- A sample of iron has the same dimensions of 2 cm x 3 cm x 2 cm. If the mass of this rectangular-shaped object is 94 g, what is the density of iron?
Today we finished looking at the Bunsen burner and the activity to answer the question: Where the hottest part of the flame would be. We also began our formal lab in the properties section.
As of now, we will be moving the test to Wednesday in order to complete the formal lab. I encourage everyone to begin studying and completing the review questions posted here on the blog. For tonight, please work on the following in your text:
Page 202 #7,8,10,11,12
Please complete the questions on the backside for the Bunsen Burner activity.
Test on Properties of Matter is on Monday:
- Particle Theory of Matter
- Classification of Matter
- Physical Properties – both qualitative (using senses) and quantitative (meausurements – density, temperature, etc)
- Chemical Properties
- Physical & Chemical Changes
- WHMIS & HHPS
