How would I answer these questions?
Transcribed Image Text:ANSWER THE FOLLOWING QUESTIONS.
1. Illustrate the Lewis dot structure of the water molecule. Explain why it is a
polar molecule.
2. Look-up and illustrate the structure of a soap molecule.
3. Explain how a soap molecule removes grease/oil from your hands.
4. All of you are aware of soap bubbles; you know they come in various sizes.
Explain how a soap bubble is created and why its size varies.
5. Why does a soap bubble exist as a sphere?
6. Why does a soap bubble on a flat surface exist as a half-sphere?
7. Liquid detergent makes great bubbles; would a concentrated or a dilute
solution of soap work best in creating large bubbles. Explain your
reasoning.
8. Given a set concentration of soap, what effect might the temperature have
on the creation of bubbles? One sample is at 5 °C and the second sample is
at 50 °C.
9. Given a set temperature, what effect might the concentration have on the
creation of bubbles?
