Question 23

Combustion

Answer 23

Substances that react with oxygen to release useful energy.

Question 24

Two Types Of Combustion

Answer 24

• Incomplete
• Complete

Question 25

Complete Combustion

Answer 25

These are compounds of hydrogen and carbon only. When they burn completely the carbon oxides to carbon dioxide and the oxygen oxides to water.

Question 26

Incomplete Combustion

Answer 26

Occurs when the supply of air or oxygen is poor. Water is still produced but carbon monoxide and carbon are produces instead of carbon dioxide.

Question 27

Substitution Reaction

Answer 27

Occurs when one atom is swapped with another atom. Alkanes undergo a substitution reaction with halogens in the presence of UV light.

Question 28

Addition Reaction

Answer 28

The Prescence of C=C (Alkenes) allows for more complex reactions to take place

Question 29

Bromine Water Test

Answer 29

When there is an alkene present in a solution the bromine water goes from orange-brown to clear. If there are Alkanes present the water will not change.
