Period 2 homework:
Analysis Questions:
1.
How
many different elements were you working with?
2.
What
was the role of the “sticks” on each atom model?
3.
Draw
two atoms of hydrogen next to your sketch of a molecule of hydrogen gas (H2).
Label the two atoms of hydrogen with a chemical formula that you think is appropriate
for them alone (when they are not bonded).
4.
What
does the 2 in the molecular formula H2O stand for? Explain.
5.
In
this activity, you modeled ethanol, hydrogen, methanol, nitrogen, oxygen, and
water. Why are oxygen gas, hydrogen gas, nitrogen gas, and carbon called
elements, while water and ethanol are called compounds?
6.
Methanol
and ethanol are both alcohols.
a.
Compare: How are the molecules of methanol and ethanol similar?
b.
Contrast: How are the molecules of methanol and ethanol different?
7.
a.
Why is the formula for methanol usually written as CH3OH instead of
CH4O?
b.
Looking at its structure, propose two ways other than C2H5OH
to write the formula for ethanol. Describe the advantages and disadvantages of
each.
8. Compare and contrast water with (against) the two alcohols you modeled. How are they the same? How are they different?
9. a. What are the strengths of this modeling kit in helping you to understand what matter is made of?
b. What do you consider to be the limitations of this modeling kit? In other words, in what way(s) does this modeling kit not show similarities and differences between water, methanol, and ethanol?

Mr goldsmith how are we suppose to read the pages and answer the questions.When we dont have the books with us
ReplyDeleteHi Matt: In your Science notebook, you should have notes and drawings from the activity in class that you can use to answer the questions. We also read the information in the book during class; you should be able to remember any information that you need. But even if you do need the book, it is available on line using the information on your "Resources for Students" sheet that I handed out early this year and told you to keep in your science notebook.
