The first stage in designing your presentation is to make a list of questions that will enable you to research the topic. Your presentation should answer these questions: What is tetanus?
What are the symptoms and consequences of the disease?
Who is at risk of developing tetanus?
How do vaccines work?
What is the history of the tetanus vaccine?
Who should receive the tetanus vaccine?
When should people receive the tetanus vaccine?
Why is this schedule important?
Has there been a change in tetanus incidence in the United States since the vaccine became available?
What are the risks of vaccination versus non-vaccination?
Do the risks outweigh the benefits?
Are there areas in the world in which tetanus is prevalent? If so, does this affect the recommendations for US vaccination?
Think about what you have heard about vaccines in discussions you have had with friends and family members or from news broadcasts. Write down two additional questions based on your observations to help you strengthen your arguments.

Problem #3 (ch. 1, problem 15)the ideal gas law provides one way to estimate the pressure exerted by a gas on a container. the law isí‘ťí‘ť=푛푛푛푛푛푛푉푉more accurate estimates can be made with the van der waals equationí‘ťí‘ť=푛푛푛푛푛푛푉푉â’푛푛푟푟â’푞푞푛푛2푉푉2where the term nb is a correction for the volume of the molecules and the term an2/v2is a correction for molecular attractions. the values of a and b depend on the type of gas. the gas constant is r, the absolutetemperature is t, the gas volume is v, and the number of moles of gas molecules is indicated by n. if n = 1 mol of an ideal gas were confined to a volume of v = 22.41 l at a temperature of 0â°c (273.2k), it would exert a pressure of 1 atm. in these units, r = 0.0826.for chlorine gas (cl2), a = 6.49 and b = 0.0562. compare the pressure estimates given by the ideal gas law and the van der waals equation for 1 mol of cl2 in 22.41 l at 273.2 k. what is the main cause of the difference in the two pressure estimates, the molecular volume or the molecular attractions?
