An Investigation into Burning Fuels & Hydrocarbons –
To find out whether the amount of carbon atoms in an alkene is related to the energy released.

PLAN

Aim:
To find out whether the amount of carbon atoms in an alkane is related to the energy released.

Research:

Alcohol Formula
General formula CnH2n+1OH + O2 > 2nCO2 + 2n+2H2O
METHANOL 2CH3OH + O2> 2C02 + 4H20
ETHANOL 2C2H5OH + O2 > 4C02 + 6H20
PROPANOL 2C3H7OH + O2 > 6C02 + 8H20
BUTANOL. 2C4H9OH + O2 > 8C02 + 10H20
PENTANOL 2C5H11OH + O2 > 10C02 + 12H20
HEXANOL 2C6H13OH + O2 > 12C02 + 14H20
I am going to burn a defined amount of alcohol using an alcohol burner, to measure the energy change by measuring the change in water temp. To hold the water I need some sort of container. This container mustn’t be very heat resistant, so it can use as much of the energy from the reaction as possible. I will use a glass beaker, as this is readily available in the classroom.
