Assignment 1:
Photosynthesis:
6CO2 + 6 H2O
→
C6H12O6 + 6 O2
Carbon dioxide + water = food + oxygen
Your group’s job is to do the following:
1. Explain what the reactants and the products are in simple terms
2. Describe how you would know it is a chemical reaction
3. Describe if this reaction gives off heat (exothermic) or takes in heat
(Endothermic)
4. Show a picture example.
Assignment 2: Respiration
Respiration:
C6H12O6 + 6 O2
→ 6CO2 + 6 H2O
Food + oxygen
Carbon dioxide + water
Your group’s job is to do the following:
1. Explain what the reactants and the products are in simple terms
2. Describe how you would know it is a chemical reaction
3. Describe if this reaction gives off heat (exothermic) or takes in heat
(Endothermic)
4. Show a picture example.
Assignment 3:
Combustion of octane gas in Oxygen:
2 C8H18 + 25 O2 →
16 CO2 + 18 H2O
Octane gas + oxygen = carbon dioxide + water
Assignment 4:
Metal Rusting:
2 Fe + O2 → 2 FeO
Iron + oxygen = rust
Assignment 5:
Baking with Baking Soda:
2NaHCO3 →
Na2CO3 + H2O + CO2
Baking Soda → SodiumBicarbonate + Water +Carbon
Dioxide
Assignment 6:
Wood Burning
CxHyOz + O2 ------> CO2 + H20
Wood + oxygen → carbon dioxide + water
Your group’s job is to do the following:
