Combustion Facts

The earliest scientific attempt to explain Combustion reaction are used everyday, something as simple as turning on a gas

range is a combustion reaction.Something as simple as lighting a match

is a combustion reaction.

What is combustion? Is a reaction an element or a

compound reacts always with oxygen, often producing energy in the form of heat and light and

water.

Real Life Examples of Combustion

An example of this combustion can be found in the news, it reads as “Man sets himself on fire after he douses his car in alcohol to kill

bedbugs and then lights a cigarette inside.”

Another example is something someone might use in everyday

life. A heater is a good example of this because in the end it produces

heat, due to the reaction.

HYDROCARBONS

The combustion of a hydrocarbon releases energy as heat

Hydrocarbons are such asMethane- CH4

Propane- C3H8

Butane-C4H10 Octane- C8H18

A combustion

reaction between an

element and oxygen is also an

example of a

combination reaction

For example, both magnesium and

sulfur will burn by reaction with

Oxygen

2Mg(s)+ O2(s) 2MgO(s)

S(s)+ O2(g) SO2(g)

What is a Combination Reaction?

Balancing Combustion Reactions

C3H8 + O2 = CO2 + H2O

C3H8 + O2 = CO2 + 4H2O

C3H8 + O2 = 3 CO2 +4 H2O

C3H8 + 5 O2 = 3 CO2 +4 H2O

Add a 4 to balance the hydrogen atoms

on each side

Add a 3 to balance the carbon At0ms

Add 5 to the oxygen to balance the amount of Atoms

C2H6O + O2 =CO2 + H2O

C2H6O + 3O2 =2CO2 + 3H2O
