combustion

Slide 3 - Mind map

Combustion
Also called burning.
Reaction with oxygen.
Main product is an oxide (often invisible gas)
Type of oxidation reaction.
Heat is given out in combination with light.

Slide 4 - Slide

A combustion reaction always takes place with

Slide 5 - Open question

Me

Slide 7 - Quiz

Give the word equation
of the combustion reaction of methane (natural gas).
Put the reaction equation (using formulae) in your notebook

Slide 8 - Open question

Combustion of methane
Give the reaction equation
of the combustion reaction of methane (natural gas).

Tekst
CH4(g)+2O2(g)CO2(g)+2H2O(l)

Slide 9 - Slide

Combustion reaction
A chemical reaction in which the oxides are formed from the elements in the reactant together with oxygen.
ABC+O2AO+B2O+CO2

Slide 10 - Slide

Kinds of Combustion
Complete = enough oxygen present
oxides with maximum oxygen atoms are formed

Incomplete = not enough oxygen
oxides with less oxygen atoms are formed

carbonmonoxide:2CH4(g)+3O2(g)2CO(g)+4H2O
CH4(g)+2O2(g)CO2(g)+2H2O(l)
soot:CH4(g)+O2(g)C(s)+2H2O(l)
