1. Suppose that the international market for beef is in equilibrium. Describe in a written sentence how the following change to a determinant of supply and/or demand will affect the equilibrium price and quantity. Illustrate each answer with a supply-and-demand diagram depicting the shift(s) and the resulting effect on price and quantity a. Outbreak of mad cow disease kills off much of the cattle stock. b. The price of chicken‚ a substitute‚ declines sharply. c.

Spectrophotometric Determination of an Equilibrium Constant. Abstract: The report presents determination of equilibrium constant for the formation of a complex ion FeSCN2+. This was accomplished using a colorimeter to measure absorbance of some known concentration solutions in order to generate the calibration curve. The equation of the graph was used to compute the equilibrium concentrations of the reactants and products‚ needed to calculate the equilibrium constant for the reaction.

Equilibrium Essay How does Equilibrium fulfil the conventions of a dystopic text? In what way does it subvert them? 1000-1500 words. A dystopia is a futuristic and technologically advanced oppressive world with an overbearing totalitarian government who maintain strict authoritarian control over its population. Dystopia’s are often concealed as utopias since everybody appears to be equal and life appears to be fair‚ but in reality freedom is greatly restricted under a dystopia. Kurt Wimmer’s Equilibrium

Chemical Equilibrium ------------------------------------------------- ------------------------------------------------- RESULTS AND DISCUSSION A. Iron-Silver Equilibrium In studying equilibrium between iron and silver‚ 0.10 M FeSO4 and 0.10 M AgNO3 were used. The balanced equation for the reaction is: FeSO4 (aq) + 2 AgNO3 (aq) ↔ Fe(NO3)2 (aq) + Ag2SO4 (s) It has a net equation of: Fe2+(aq) + Ag+(aq) ↔ Fe3+(aq) + Ag(s) This part of the experiment

Spectrophotometric Determination of an Equilibrium Constant Introduction: In this experiment‚ you will study the reaction between aqueous iron (III) nitrate‚ Fe(NO3)3‚ and potassium thiocyanate‚ KSCN. They react to produce the blood-red complex [Fe(SCN)]2+. Fe3+ + SCN- ( [Fe(SCN)]2+ The equilibrium constant expression may be expressed as: K = [pic] You will prepare a series of standard solutions that contain known concentrations of [Fe(SCN)]2+ and will determine

What Factors Affect Chemical Equilibrium? Introduction: In investigation 14‚ “What Factors Affect Chemical Equilibrium?”‚ the purpose was to find out which reagents caused a change in the chemical equilibrium. A deep red color was formed when Iron Nitrate [Fe(NO3)3 (aq)] was mixed with water and Ammonium Thiocyanate [NH4NCS (aq)]. The product of these two reactants was Iron Thiocyanate(FeNCS). After different trials of mixing the given reagents

ANSWERS) One point questions: 1. a) How can time be incorporated into the theory of consumer behavior (think opportunity costs)? Time also has a value‚ so it also should be considered in decision making and utility maximization. The total price of a product should also include the time spent in consuming the product. (how much you make per hour). Usually when people consider their time‚ their consumer behavior appears to be more rationale. b) Explain the following comment: “Want to make
