|
The complete combustion of a hydrocarbon produces carbon dioxide and water. |
|
What are the products of the complete combustion? Stretch - Recall the products of combustion reaction using images to prompt students.
Challenge -
write and balance the symbol equation for the combustion reaction for methane |
|
|
|
Students should be able to write balanced equations for the complete combustion of hydrocarbons with a given formula. |
|
What is the balanced symbol equation for the complete combustion of methane (CH4)? (include state symbols in your answer) Teach/Remind students that combustion reactions are examples of oxidation reactions |
|
|
|
During combustion, the carbon and hydrogen in the fuels are oxidised. |
|
What happens to the carbon and hydrogen atoms during combustion reactions? |
|
|
|
The combustion of hydrocarbon fuels releases energy. |
|
What is the useful outcome of the combustion of hydrocarbon fuels? Think > pair > share
why are combustion reactions useful? |
|
|
|
Knowledge of trends in properties of hydrocarbons is limited to: ? boiling points, ? viscosity, ? flammability. |
|
Describe how the each of the following properties changes as the length of hydrocarbon chains within a fraction increases:
a) Boiling point
b) Flammability
c) Viscosity Investigating the flammability (how easy is it to ignite and cleanness of flame) and viscosity of different hydrocarbons (timing how long it takes to drip down the tile)
Students should identify the IV and DV and describe the control of the CV.
