Chemical Bonding and Molecular Geometry Paper

Page 1 Writing Assignment #3

 

Objective: Writing about scientific principles and phenomena is an increasingly important skill in the 21st century. This assignment is designed to help you understand a major concept covered in this unit while also helping you develop your science writing skills. One key to effective science writing is explaining how science can be used in everyday life. You’ll do this in a 500-600 word paper. You should:

 

1) Formulate and answer a question

Sample questions

 

Select a concept that was covered in lecture between October 23 and November 19 and formulate a question. Use this question as the title of your essay.

 

  • What factors determine the pressure of a gas?
  • What are similarities and differences between diffusion and effusion?

 

 

2) Choose one of the following:

 

Explain how this applies to your life in an essay Explain how this applies to a friend or family member in a letter

 

 

Write a 500-600 word essay answering this question, and discuss how the information could be

 

Write a 500-600 word letter to a family member or close friend, answering this question, and discuss how the information could be

useful to you in your own life. Be sure to include some concrete information that was covered in this unit, explaining why the information is relevant to your life and useful for you. Be sure to explain how the information applies to you personally and give examples.

useful to this person in their own life. Be sure to include some concrete information that was covered in this unit, explaining why the information is relevant to this person’s life and useful for this person. Be sure to explain how the information applies to this person and give examples.

 

 

 

Examples of applications

 

  • The ideal gas law (PV = nRT) describes how a gas’s temperature, amount, and volume are related to its pressure. When an aerosol spray can is heated, the volatile liquid becomes a gas, producing an increase in pressure that may cause the can to burst. In your own life, you can prevent damage to your home by storing aerosol cans away from heat sources.

 

  • Gases move from areas of higher concentration to areas of lower concentration through the process of diffusion. You’ve experienced the diffusion of CO2 molecules in your own life if you’ve ever left an open can of soda sitting out for so long that it goes flat.

 

  • The ideal gas law is used to determine the amount of N2 gas that must be produced to rapidly inflate automobile airbags to the pressure necessary to protect the car’s occupants. Thanks to this technology, you have a decreased risk of being seriously injured if you are involved in a car accident in your own life.
