Fall 2013 ECO 2306 – Principles of Microeconomics Homework 4 Answer Key Part I: True/False and Multiple Choice 1. In equilibrium in the strawberry market‚ strawberries sell for $1.50 a quart. If the government institutes a price floor of $1 per quart of strawberries‚ the result will be a surplus of strawberries. a. The preceding statement is TRUE. b. The preceding statement is FALSE. 2. A price ceiling will lead to deadweight loss as a result of overproduction of the good at the higher ceiling

Hardy-Weinberg Equilibrium One of the most difficult concepts to understand about the process of evolution is how changes in the genetic composition of a population affect the phenotypic composition of a population‚ and how both ultimately act to allow evolution of the species. Charles Darwin’s theory of evolution emphasizes that populations‚ not individuals‚ evolve. The purpose of my experiment was to test the allele and genotype frequencies. Alleles for a gene are represented by letters of

Market Equilibrium Process Economics/561 Monday‚ February 6‚ 2012 Professor Michael Shackelford Market Equilibrium Process According to "Business Week" (n.d.) “Market equilibrium is a situation in which the supply of an item is exactly equal to its demand. Since there is neither surplus nor shortage in the market‚ price tends to remain stable in this situation.” (Market Equilibrium). The market equilibration process is very important to manufactures and sellers in the marketplace

Experiment 3: Evaluation of Gas Constant Purpose: The purpose of this lab is to demonstrate the ideal gas law under ordinary conditions. In this lab‚ the variables in the ideal gas law are known or can be found aside from the constant R. Thus‚ the R values can be found and relatively determine the relevancy of the ideal gas law to the lab conditions. The ideal gas law was tested using the reaction: Mg (s) + 2HCl2 (aq) H2 (g) Procedure: 1. Ribbons of magnesium (5) were cut to the approximate

CHEMISTRY DETERMINATION OF ENTHALPY CHANGE OF NEUTRALIZATION IA Criteria Assessed: DCP CE MS Introduction When an alkali neutralizes an acid‚ a salt and water are formed. Aqueous hydrogen ions (H+(aq)) from the acid react with the hydroxide ions (OH- (aq)) from alkali‚ forming water. The identity of salt will depend on the nature of the acid and alkali used. H+(aq) + OH- (aq) → H2O(L) The combination of H+ and OH- ions in this way releases energy. In this practical‚ the

Kim Dec. 15‚ 2011 Abstract Two experiments were conducted to figure out the value of the formation constant of tetraamminecopper(II)‚ Kf‚ with different methods and which experimental method produces more accurate result. One was electrochemistry using a Daniel cell and the other one was spectrometry by estimating concentration of complex solution using a calibration curve. The formation constant of cupric ammine complex Cu(NH3)42+‚ Kf‚ came out with 1.93x10^15 using electrochemical cell method

Supply and demand is one of the most fundamental concepts of economics and it constitutes the backbone of a market economy. Demand refers to how much (quantity) of a product or service is desired by buyers while supply represents how much the market can offer. The quantity supplied refers to the amount of a certain product manufacturers are willing to supply given a set price. (Investopedia.com - Your Source For Investing Education‚ 2011). The law of supply and demand defines the effect that the
