Chain isomer

A molecule that contains the same molecular formula but has a different arrangement of the carbon chain

9

Functional Group Isomer

A molecule with the same molecular formula but different functional groups (cycloalkane Vs alkene)

10

Thermal Cracking

1000⁰C and 70 atm. Makes alkenes, used for polymers.

11

Catalytic cracking

Zeoilite catalyst and 450⁰C, making motor fuel and aromatic hydrocarbons.

12

Complete combustion

Burning a substance completely in oxygen to produce CO₂ and H₂O

13

Global warming

Caused by release of CO₂

14

Incomplete combustion

Burning a substance in a limited supply of oxygen, producing Solid Carbon and Gaseous Carbon Monoxide (Toxic)

15

Global dimming

Caused by the release of solid Carbon

16

Flue Gas Desulphurisation

CaO + SiO₂ →CaSiO₃
This is a neutralisation reaction
