Extra credit due by the end of the period Friday.

All textbooks must be returned!

I will find out how much $ it will cost you if you can't find it. 

There will be a lab test on Friday!

 

The test on chapter 11 will be on Wednesday

Bring your best friends

Practice: http://www.ck12.org/user%3Aemonahan/book/Chemistry-Types-of-Chemical-Reactions-Quiz/section/1.0/

Do Chapter 11.1 thru 11.7.

 

ALL QUIZZES MUST BE DONE BY June 7th BEFORE Class!!!

Do the practice online, then use phone to take a picture of your quiz score, then e-mail it to me at  [email protected]

or you can come in before school on monday or tuesday!

Zero's for any quizzes not completed BEFORE class on Tuesday!!

Hello Chem Students!

I've attached a practice worksheet for the Baking Soda Lab

(If you want to practice before your Lab Quiz???)

Complete Thursday's "Lab Report".

 

We will begin a new lab tomorrow. Complete Lab report for Monday.

 

If you are not here, you should get a copy of the lab report, get data from a friend who did it and complete the lab report for class Monday.

 

We will go over both labs on Monday (day 7). You will have a Lab Quiz on Thursday May 26th.

There will be a mole problems quiz tomorrow!

mole Quiz Tomorrow

 

Here are some practice problems (with answers)

1) Calculate the number of molecules in 1.058 mole of H₂O

2) Calculate the number of atoms in 0.750 mole of Fe

3) Calculate the number of molecules in 1.058 gram of H₂O

4) Calculate the number of atoms in 0.750 gram of Fe

5) Which contains more molecules: 10.0 grams of O₂ or 50.0 grams of iodine, I₂?

6) A solution of ammonia and water contains 2.10 x 10²⁵ water molecules and 8.10 x 10²⁴ ammonia molecules. How many total hydrogen atoms are in this solution?

Answers: (assuming this website is correct)

Now the solutions:

1.058 mole x 6.022 x 10²³ molecules/mole

0.750 mole x 6.022 x 10²³ atoms/mole

1.058 g x 1mol/18.0g x 6.022 x 10²³ molecules/ 1 mole

(0.750 g x 1mol/ 55.85g x 6.022 x 10²³atoms/1 mole

---

5) Basically, this is just two two-step problems in one sentence. Convert each gram value to its mole equivalent. Then, multiply the mole value by Avogadro's Number. Finally, compare these last two values and pick the larger value. That is the one with more molecules.

6) Ammonia's formula is NH₃ and water's is H₂O. Ammonia has three atoms of H per molecule and water has two atoms of H per molecule.

ammonia's contribution:

8.10 x 10²⁴ times 3 = 2.43 x 10²⁵ H atoms

water's contribution:

2.10 x 10²⁵ times 2 = 4.20 x 10²⁵ H atoms

sum them up:

2.43 x 10²⁵ + 4.20 x 10²⁵ = 6.63 x 10²⁵ H atoms

Here are the 2 problems we did together AND 2 more for you to do before we meet again! Don't forget CK-12 chapter 10.1-3... we have to have quizzes on them so do the practice.

Go to: http://www.ck12.org/book/CK-12-Chemistry-Concepts-Intermediate/section/10.0/
