1. Creating a chemical reaction
Burning Sugar

2. Burning the sugar causes the combustion of sugar.
Sucrose (Table Sugar) Glucose
C12H22O C6H12O6  
 Burning the sugar causes the combustion of sugar.
Not all of the sugar undergoes combustion and you are left with a black, tarry substance that is mostly composed of carbon.
Careful observation may also show the formation of water (which may then evaporate) and possibly the bubbling up of CO2 escaping the combusting sugar.

3. Things to Think About
What changes did you observe as a result of heating the sugar?
Did a chemical reaction occur?
What indications of a chemical reaction do your observations suggest?
What caused the reaction to take place?
The only substance we heated was sugar. What other substance did it react with to form new products?
The formula for the sugar glucose is C6H12O6. The formula for the sugar sucrose (table sugar) is C12H22O12. When sugars burn during a combustion reaction what gas do you think is produced?
Based on your observations, what are the signs a chemical reaction has occurred?

5. BUT WHAT DOES ALL OF THIS MEAN?
Sucrose: 12O2 + C12H22O11 → 12CO2 + 11H20
Glucose: 6O2 + C6H12O6 → 6CO2 + 6H20
BUT WHAT DOES ALL OF THIS MEAN?
These are models for the complete COMBUSTION of table sugar(sucrose) and glucose!
These are called chemical equations!
Chemical equations show the chemical formula of each substance in a reaction.
*There are 3 parts of a chemical equation:
Reactant, Yield, Product
*Refer to your tape-in!
