Edexcel IGCSE Chemistry Lecture 33 - Burning Hydrocarbons

Powerpoint lecture covering the following in a modern, concise format:

Specification Point 4.11 - Know that a fuel is a substance that, when burned, releases heat energy.

Specification Point 4.12 - Know the possible products of complete and incomplete combustion of hydrocarbons with oxygen in the air.

Specification Point 4.13 - Understand why carbon monoxide is poisonous, in terms of its effect on the capacity of blood to transport oxygen.

Specification Point 4.14 - Know that, in car engines, the temperature reached is high enough to allow nitrogen and oxygen from air to react, forming oxides of nitrogen.

Specification Point 4.14 - Know that, in car engines, the temperature reached is high enough to allow nitrogen and oxygen from air to react, forming oxides of nitrogen.

Specification Point 4.15 - Explain how the combustion of some impurities in hydrocarbon fuels results in the formation of sulphur dioxide.

Specification Point 4.16 - Understand how sulphur dioxide and oxides of nitrogen contribute to acid rain.

Specification Point 4.17 - Describe how long-chain alkanes are converted to alkenes and shorter-chain alkanes by catalytic cracking.

Specification Point 4.18 - Explain why cracking is necessary, in terms of the balance between supply and demand for different fractions.
