| What bacteria makes PHB? | Bacillus Megaterium |
| What are Hydrocarbons? | Hydrocarbons are organic compounds containing only atoms of carbon and hydrogen. |
| What is a homologous series? | A Homologous series is a group or family of compounds that have similar structures and chemical properties, for example Alkanes, Alkenes. |
| What is a Monomer? | A monomer is a small molecule many of which can be joined together to form a long chain molecule called a polymer. |
| What is a Polymer? | A Polymer is a large molecule consisting of a large number of identical small molecules called monomers, joined together. |
| Define Polymerisation. | Polymerisation is the production of Polymer from a monomer. |
| Name the three main stages of the production of Polyethylene | 1.Initiation 2.Propagation 3.Termination |
| What is Biomass? | Biomass is organic matter produced by plants or animals. |
| What is Cellulose? | Cellulose is one of the main compounds of biomass. It is the most abundant carbohydrate on Earth. |
| What is a condensation polymer? | A condensation Polymer is a compound, when its molecules join together forming a Polymer it releases a small molecule (usually water). |
| What are Biopolymers? | Biopolymers are Polymers that occur naturally or are made from naturally occuring substances. |
| Define Molar Heat of Combustion. | Molar heat of combustion is the heat energy released by the combustion of 1 mole of a fuel. |
| What is the main method used to produce unsaturated hydrocarbons such as ethene? | By Thermal Cracking of suitable feedstock. |
| What is a substitution reaction? | A reaction in which an atom in a molecule is replaced by another atom or group of atoms. |
| Define "Dehydration". | Dehydration is a chemical reaction in which water is removed from a compound. |
| What is Fermentation? | Fermentation is a process in which glucose is broken down to ethanol and carbon dioxide by the action of enzymes present in yeast. |
