In one or two paragraphs, discuss the various methods that large companies (such as Standard Oil) used to gain vast amounts of wealth during the last 1800’s and early 1900’s. Also mention the governments reactions to their business practices( both state and federal governments) and whether those reactions were successful. You can be broad in the state reaction, but should describe the 2 specific laws the federal government used

In one of the routine analyses, Dr Entropy found that the concentration of phosphate had increased from 0.0090 mg/L to 0.220 mg/L. This will require a lengthy investigation and detailed report into the causes. Being the master of disorder, he considers an act of serious scientific misconduct – diluting the sample to reduce phosphate concentration to the maximum allowable level of 0.100 mg/L, and hoping that no-one notices.

If the volume of the original sample with concentration 0.220 mg/L is 10.0 mL, what should be the final volume of solution in order to dilute it to 0.100 mg/L? 

Can you assist in showing how to work this out?

In one of our lecture presentations in this module is a quotation by the author, Vargas Llosa.  Please read his comment below about the role of literature in society and respond in approximately one 250 word paragraph, stating whether you agree or disagree with the sentiments expressed by the author. Please also respond to at least one other student in our class.

“A society without literature, or a society in which literature has been relegated—like some hidden vice—to the margins of social and personal life, and transformed into something like a sectarian cult, is a society condemned to become spiritually barbaric, even to jeopardize freedom.”Vargas Llosa

Your initial response should be around 250 words. Your response to a classmates’ discussion should be around 100 words and add to the discussion (i.e. posing questions, reflecting on their response, etc.). All posts and responses should contain proper grammar, be free of spelling errors, be substantial, and reflect critical thinking. 

Remember: Be supportive, considerate, and constructive when replying to your classmates.

In one experiment, the mass of water is 94.8 grams, the initial temperature of the water is 69.9oC, the mass of liquid nitrogen added to the water is 63.0 grams, and the final temperature of the water, after the liquid nitrogen has vaporized, is 38.3oC.Specific heat of water = 4.184 J K-1g-1How much heat is lost by the warm water?Heat lost = JWhat is the heat of vaporization of nitrogen in J g-1?Heat of vaporization = J g-1What is the molar heat of vaporization of nitrogen?Molar heat of vaporization = J mol-1Trouton’s constant is the ratio of the enthalpy (heat) of vaporization of a substance to its boiling point (in K). The constant is actually equal to the entropy change for the vaporization process and is most often a measure of the entropy in the liquid state. The value of the constant usually lies within the range 70 to 90 J K-1mol-1, with a value toward the lower end indicating high entropy in the liquid state.The normal boiling point of liquid nitrogen is -196oC. Based upon your results above, what is the value of Trouton’s constant?Trouton’s constant = J K-1mol-1
