Atoms, Compounds, Chemical Reaction, Properties of Water

Instruction
This review homework assignment is a major opportunity to revisit the information we covered in the readings and the lectures.
As you move through each task, be sure to focus on what you are trying to learn.
Many of the tasks in review homework assignments require drawings. You will create the drawing, take a picture of it, and upload the image to you submission in canvas. Please make sure the image is facing the right direction and that it is well lit and clearly visible.
While you do not have to be an artist, I expect to be able to understand what you have drawn.
Include labels and captions explaining what you have drawn so that I can see that you worked to understand the information associated with each task.
Most of your drawings will be based on diagrams in the book. I understand that these drawings will look like the images in the textbook. It is how you caption and label the drawings that will make them your own.
For written answers, please use your own words and do not rely on the internet. Any answers derived from sources other than the textbook and the lecture content (like the internet or other students’ work) will result in a zero for the entire assignment.

Questions
1. Draw, label, and caption a diagram of a carbon atom. How many covalent bonds can it form?
2. Draw an electron distribution diagram for water. Show that water is polar. Label the following items in your drawing:Molecular formula
Correct number of protons for each atom
Correct number of neutrons for each atom
Nucleus of each atom
Correct number and distribution of electrons for each atom (don’t forget to use accurate electron shells and orbitals).
Electrons involved in covalent bonding
A minus sign (-) indicating the negatively charged area of the molecule
A plus sign ( ) indicating the positively charged area of the molecule

3. Write out the chemical reactions for photosynthesis and cellular respiration. The net equation for these chemical reactions can be found in your textbook.
4. Draw, label, and caption an atom other than carbon that can form four covalent bonds. Why can it form these four bonds?
5. When you put a pot of water on then stove, it takes awhile for the water to get hot. Why doesn’t the water get hot immediately after heat is applied? Without looking at the lecture slides, what does this have to do with the climate in regions that are close to the ocean?
