Aim: How are organic compounds different from inorganic compounds?

What elements are all living things made of? Hydrogen, Carbon, Nitrogen, & Oxygen

When atoms bond together they are called…… Join When atoms bond together they are called…… MOLECULES

Bonds store energy How do we get energy from molecules? Bond must be broken to release energy.

Chemistry Shorthand: Formulas CO2 A chemical formula represents the chemicals found in a compound or molecule. How many carbon atoms in 1 molecule of CO2? 1 How many oxygen atoms in 1 molecule of CO2? 2

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

Structural Formula Bonds Structural formula shows the kinds, numbers, and the arrangements of atoms. It also shows the bonds

Chemical Equations and Reactions A + B C or C A + B Products Reactants

Example of a Chemical Reaction: C6H12O6 + O2 6H2O + 6CO2 Carbon dioxide Glucose Oxygen Water How many water molecules are produced? Which are the reactants? Which are the products? How many glucose molecules are used? How many carbon atoms are present in a molecule of glucose?

Types of molecules Organic Inorganic

What do organic molecules have in common? Examples C & H

What do inorganic molecules have in common? ONLY C or ONLY H or neither

Comparing Molecules Inorganic Organic 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

Organic compounds are made by Living Things CO2 + H2O O2 + C6H12O6 organic inorganic
