Alum Lab Conclusion The purpose of this laboratory was to use two different techniques to attempt to identify the melting point and the mole ratio of hydrated water to anhydrous aluminum‚ potassium‚ and sulfate of AlKSO4. The hypotheses were: if the alum was put in a capillary tube the melting point of alum will be able to be determined; and the water of hydration in alum crystals will be possible to determine if the alum is heated with a Bunsen burner.

Conclusion In this experiment‚ we measured the mass of 4 gasses; oxygen‚ carbon dioxide‚ helium‚ and lab gas. We took a Ziplock bag‚ and turned into a non-stretchy balloon‚ and filled with each gas and measured the apparent mass then calculated the actual mass‚ then find a ratio between the mass of oxygen and the other gasses. We tried to keep the pressure about the same each time so our calculations would be more accurate. We found out that the heaviest was carbon dioxide‚ and the lightest

spanking is an effective way to teach children right from wrong in her post titled "Spanking: A Useful Tool." In her post she states "I don’t see anything wrong with an occasional‚ well timed‚ swat on the backside. I feel that the key‚ though‚ is to explain to the child what they did wrong‚ how they need to make it right and balancing the spanking with lots of love." (Dressler) She then goes on to explain that she has spanked all three of her children‚ and that they are all respectful of others and

“Correlation doesn’t equal causation” Albert Einstein once said “The world is in greater peril from those who tolerate or encourage evil than from those who actually commit it.” At this point in my life‚ I couldn’t have found that statement to be any truer. I’m an activist‚ an avid one at that. I try to fight evil educating others‚ on what not many people have ever even questioned before; Vaccines. When I tell most people this‚ their first reaction is “oh‚ you’re one of those people” or “I get it

This essay will explore the nurse’s professional responsibility for safeguarding vulnerable patients. It will identify vulnerabilities specific to Blanche‚ a ninety year old lady with medical and physical problems (appendix 1). Other issues such as patient rights‚ autonomy and accountability will be discussed. It will consider the nurses professional behaviour and interventions to support Blanche. The Department of Health (DH‚ 2000a‚ p.8) define a vulnerable adult as a person over eighteen

In conclusion to the distillation lab‚ I think our data shows that our experiment went well. Our graph resembles the graph in the lab handout (graphs attached to lab notebook sheets). The fractional distillation shows the sharp slope between when the cyclohexane burns off and mostly only toluene remains. The microscale graph seems to be accurate because it shows the large jump where the cyclohexane is burned off. To view the apparatuses used in the experiment look at the attached pictures. To

Barry Allahyar Dr. Dodd CHEM 2122 2010-09-16 Experiment 19: Fischer Esterification‚ Conclusion The objective in this experiment was to efficiently perform an Fischer esterification of 1-butanol and acetic acid to form water and n-butyl acetate‚ and to confirm the esterification using IR spectroscopy analysis. It was found that 0.734 grams of n-butyl acetate was formed with a percent yield of 61%. The product was confirmed using IR spectroscopy and boiling point confirmation. The reaction mechanism
