Success Criteria: I will be able to combust a hydrocarbon found in ripening fruit and model simple hydrocarbons..
Warm-Up:
At the grocery store bananas are .67 cents a pound, but the organic bananas are $1.25 per pound. What does organic mean?
Does the term organic mean the same to a scientist?

Ch 1 Activity 9: Organic Substances
Success Criteria: I will be able to correctly name simple hydrocarbons..
Warm-Up:
1. How many bonds does a carbon atom form?
2. How many bonds does a hydrogen atom form?
3. Draw a molecule with 1 carbon atom and 4 hydrogen atoms.

6. Review from Friday
Ethylene / Ethene is present in the peels of ripening fruit and is flammable
Ethylene is a hydrocarbon
Hydrocarbons are compounds made of only carbon and hydrogen atoms
“Organic chemistry” is the study of compounds containing carbon

Hydrocarbons are “saturated” if every carbon atom has all the possible hydrogen atoms bonded to it (all single bonds)
Saturated hydrocarbons are called “alkanes” and they end with the suffix -ane

Hydrocarbons are “unsaturated” if every carbon atom does not have all the possible hydrogen atoms bonded to it (it has double or triple bonds)
Unsaturated hydrocarbons with double bonds are called “alkenes” and they end with the suffix –ene

Ch 1 Activity 9: Balancing Equations
Success Criteria: I will be able to balance equations according to the law of conservation of mass..
Warm-Up:
What is wrong with the image of s’mores below?
Assuming a s’more requires two graham crackers, one marshmallow, and one piece of chocolate, how many s’mores could you make with the ingredients shown?

14. Propane and oxygen yields carbon dioxide and water
Conservation of Mass
Law of Conservation of Mass: matter cannot be created nor destroyed
So, if an atom is found on one side of an equation, it must also be found on the other side of the equation
Consider the combustion of propane below
C3H8 + O2  CO2 + H20
Propane and oxygen yields carbon dioxide and water

15. Propane and oxygen yields carbon dioxide and water
Conservation of Mass
C3H8 + O2  CO2 + H20
Propane and oxygen yields carbon dioxide and water
Because matter cannot be created nor destroyed, the atoms that appear on one side of an equation must also appear on the other side

16. Balancing Equations Write the unbalanced equation.
Count the number of each type of atom on both sides of an equation
Add coefficients (big numbers in front of the compound) until the number of each type of atom are equal (hint: start by balancing an element that appears in only one reactant and product first)
Do not add subscripts as this will change the formula.

18. Propane and oxygen yields carbon dioxide and water
C3H8 + O2  CO2 + H20
Propane and oxygen yields carbon dioxide and water
C3H O  CO H20
C3H O  CO H20
