Case 2-59 1(a) The previous purchase price that was $10/gallon of endor and the average cost of $9.50/gallon of endor are sunk costs. These are costs that were incurred in the past and will not have any impact on future costs; these costs are irrelevant to any future decision. Details Amount ($) Number of gallons 900 Cost per gallon 11.50 Total Cost 10‚350 (900 x 11.50) The material will not be purchased at its current price ($11/gallon)‚ therefore this cost is too irrelevant.

1991 was quite a historic year. It marked the 200th anniversary of the birth of Michael Faraday (who has a strong claim to be regarded as the first Physical Chemist)‚ the 150th anniversary of the formation of the Chemical Society of London (now the Royal Society of Chemistry) and the 50th anniversary of the opening of the Oxford Physical Chemistry Laboratory. As the first Head of the Laboratory‚ Professor Sir Cyril Hinshelwood‚ commented on the occasion of the Centenary Celebration of the Chemical

Strontium Manganese Oxide Introduction The ternary inter oxide SrMnO3 was first characterized by XRD by Negas and Roth []. This perovskite type inter oxide crystallizes in the hexagonal form with the space group P63/mmC(194). This inter oxide is of considerable interest to materials scientists owing to its ability to accommodate a high degree of anion vacancies‚ crystal structure and its high Neel Temperature (TN). It also exhibits polymorphism with two different cubic and hexagonal structures

Electrolytic Solutions Solutions are sometimes grouped according to their ability to conduct electricity. Substances whose solutions conduct electricity are called electrolytes and those that do not conduct electricity are called nonelectrolytes. Also electrolytes can be strong or weak. Under strong electrolytes we have NaCl and CaCl2 which are ionic compounds‚ HCI‚ HNO3‚ HBr and H2SO4 are under acids and NaOH‚ KOH‚ and LiOH are under bases. Weak electrolytes are ionic compounds and slightly

Introduction In this paper‚ we will attempt to research how freight costs can be reduced. We will evaluate three possible outcomes as well as create an operational definition of the research problem. We will identify the constructs for the operational definition and point out the benchmarks used for measurements. The outcomes will be compared to the operational definition. An outline for addressing or finding a solution will also be included. Evaluate three possible outcomes to your research
