Textbooks, the lab manual, AND CURRENT JOURNALS should be consulted. The "references" section is for items which you "footnote" in the text. WEB PAGES SHOULD NOT BE USED (with the exception of the online versions of printed materials) as they are neither static nor peer-reviewed. MANY OF YOU HAVE NEVER USED ANYTHING OTHER THAN GOOGLE FOR RESEARCH UP TO THIS POINT IN YOUR EDUCATION... THAT IS VERY SAD. GOOGLE DOES NOT PROVIDE AN EXHAUSTIVE EDUCATIONAL OR SCIENTIFIC SEARCH. Online research can be useful in locating reference data, but caveat emptor- the base source should be cited and you should verify that the material you are citing is actually in the base source . (ie- How you found the source is irrelevant, but claiming that "the internet said the info was in that source" when the information is not, or the source doesn't exist or is incorrect, is a great way to get your paper rejected.) An "articles consulted" or bibliography section may be included for reference materials you used but which you do not directly reference in the text of your report, though this is nonstandard . The references should be in the following format, per The ACS Style Guide . Please note that different journals have different standards- there is no universal agreement on reference format, but you should use ACS format. If you don't want to buy the book, the references section is available online for free (as of 9/2011).
The hypothesis was not correct. While two of the solutions caused the eggs to increase in mass, syrup caused the egg to lose mass. This shows that the syrup was hypertonic to the solution inside of the egg, causing water to diffuse out of the egg to try and establish equilibrium. The egg’s mass increased in the distilled water and vinegar because they were hypotonic to the solution in the egg, causing water to diffuse into the cell. The shell on the egg dissolved because the egg shell is made of calcium carbonate and vinegar contains acetic acid. These two can react to produce calcium acetate and carbonic acid which then decompose into water and carbon dioxide.
