Introduction
Hello students! This webquest will help you find out more about one of the hydrocarbon reactions - Hydrocarbon combustion!
Source -
Task
1. To cause the combustion reaction, hydrocarbon must react with....
- water
- oxygen
- chlorine
2. Hydrocarbons can be as...
- solid, gas, liquid substance
- solid, gas substance
- only liquid substance
3. What products are given out as hydrocarbns are burning?
- Carbon dioxide
- Carbon dioxide + water
- Water
4. What happens to water when the gas will reach it?
- It becomes solid and does not change the color
- It changes color to black
- It changes the color to milky white
5. When the gas reaches water, how much time is needed to see the reaction?
- Approximately 15 seconds
- About 1 minute
- Reaction happens immediately
Process
Your task is to complete the test by choosing one of the three given options. In each question there is only one correct answer! Use the information that is avaible in this video -
Evaluation
Now after you have completed the test, compare your answers -
- oxygen
- solid, gas, liquid substance
- carbon dioxide + water
- It changes the color to milky white
- Reaction happens immediately
If you answered 5 out of 5 questions right, you have mastered this subject.
If you answered 4 out of 5 questions right, well done.
If you answered 3 or less out of 5 questions right, you should watch the video again and recomplete the test!
Conclusion
Now you know that not only heat and light is produced as hydrocarbon burns, but also that other products are given out, which you can't normally see.
This information will definitely be useful for your future chemistry lessons!
