What is Carbon
400
CO2, also known as carbon dioxide, is a covalent compound. Please answer the following about this compound:
1. Will it have a charge?
2. What kinds of bonds form?
3. Will it dissolve in oil?
1. No charge
2. Non-Polar Covalent Bonds
3. Yes it will
400
Draw a Bohr Model for CO2 and be specific about the kind of bonds formed
Non-Polar Covalent Bond

Describe why Magic Sand could be useful in cleaning up an oil spill in the ocean?
Since Magic Sand is Hydrophobic, it will stick to the oil but NOT to ocean water. Therefore, magic sand can be sprinkled on the ocean, which can help people mop of the oil off the ocean surface.

How can you wash butter off of your hands? You must use at least 3 vocabulary words for full credit.
Butter is non-polar.
Water is polar.
To wash butter off your hands you must use soap. Soap will create an emulsion, where the polar head attaches to water and non-polar head attaches to soap.
