1
AIM: What is the difference between organic and inorganic molecules?
DN: What elements are all living things made up of?
2
What elements are all living things made of?
Carbon, Hydrogen, Oxygen, Nitrogen COHN
3
When atoms bond together they are called……
Join When atoms bond together they are called…… MOLECULES Bonds join atoms to form molecules. Bonds store energy
4
When is energy released?
When bonds are broken.
5
Chemical Formulas Represents the chemical makeup of a compound or molecule. CO2 How many carbon atoms in 1 molecule of CO2? 1 2 How many oxygen atoms in 1 molecule of CO2?
6
How do we write chemical compounds using symbols?
What is H20? How many hydrogen atoms in 1 molecule of water? 2 How many oxygen atoms in 1 molecule of water? 1
7
shows the kinds, numbers, and the arrangements of atoms.
Structural Formula shows the kinds, numbers, and the arrangements of atoms. It also shows the bonds
8
Chemical Equations and Reactions
A + B C or C A + B Raw materials Products Reactants/Raw Materials: What is being used, left of the arrow Products: What is being synthesized (made), right of the arrow
9
Example of a Chemical Reaction:
C6H12O6 + O2 6H2O + 6CO2 Carbon dioxide Glucose Oxygen Water Which are the raw materials? Which are the products? How many carbon atoms are present in a molecule of glucose? 6 How many water molecules are produced? 6 1 How many glucose molecules are used?
10
Types of molecules Inorganic Organic
11
What do organic molecules have in common?
Examples C & H Carbon and hydrogen ** It can have other elements in it as well but must have both C and H!!
12
Organic compounds are made by Living Things
CO2 + H2O O2 + C6H12O6 organic inorganic
13
What do inorganic molecules have in common?
C OR H OR neither
14
Organic vs. Inorganic Inorganic Have C or H or neither, but never both at the same time. Can be found in living things Organic Have C & H together Made by living things
15
CIRCLE all the organic molecules
H2O NaOH FeO3 CO2 C6H12O6 CO HCl C2H6 C18H36O2 CaO H2CO3 C3H6 CaCO3 C2H5OH NaCl CH3OH HNO3 CuSO4 NH3 KCl MnCl2 KMnO4 H2SO4 NO2 SO3 HF C8H18 Na2SO4 CH3COOH HBr
