Key Area 2.4 - Combustion Flashcards
What is a fuel
A substance which reacts exothermically with oxygen to produce energy
What are the products of incomplete combustion
Co
Water
C soot
Name some high energy molecules
Glucose Sucrose Fructose Lactos Maltose Glycogen Carbohydrates (CHO)
Give examples of a monosaccharide
Glucose
Gives examples of a polysaccharide
Starch and cellulose
Give examples of a disaccharide
Sucrose and maltose
What is polymerisation
Polymerisation is a chemical reaction where small monomers like glucose join together to create a polymer such as starch
What is condensation eliminisation
Monomers join together loosing a small molecule in the process, usually water
What is the equation for the combustion of glucose and photosynthesis
Glucose + oxygen = carbon dioxide + water
What is fermentation
A chemical reaction controlled by the enzyme zymase which converts glucose to ethanol and carbon dioxide
What does the Benedicts solution test for
Fructose glucose and maltose
What is combustion
When a substance burns reacting with oxygen to produce energy. Combustion is an exothermic reaction
