OPIM Assignment 4 1. Cu = 24-11 = $13 Co = 11-7 = $4 Critical ratio = 13/(13+4) = 0.7647 μ = 30‚000 σ = 10‚000 Using normal distribution function (=norminv(0.7647‚30000‚10000))‚ the optimum order quantity is 37‚216 jerseys to maximize profit. 2. Quantity = 32‚000 First‚ we normalize the order quantity to find the z-statistic z=Q-μσ=32‚000-25‚00010‚000=0.7 We then look up the standard normal loss function. The expected lost sale is given by. Lz=0.1429 Therefore‚ the expected lost

Purpose: The purpose of this experiment is to: determine the limiting reactant of a chemical reaction that involves iron filings and a copper sulfate solution. Second‚ to determine the mole ratios between iron and copper and to show that a single replacement reaction occurs when iron and copper sulfate react with each other. And lastly‚ to determine/calculate the percent yield to better analyze the chemical reaction between iron and copper sulfate to produce copper and iron sulfate. The method

to copper (Cu) in the reaction MATERIALS • Copper wire (30 cm) • Large test tube • 250 ml beaker • Silver nitrate (AgNO3) powder • Dilute AgNO3 solution • Distilled water • Electronic balance • Glass stir rod • Watch glass PRE-LAB DISCUSSION A single replacement reaction occurs when an uncombined element “replaces” another element that is contained in a compound. You will prepare and observe a single replacement reaction in this lab. Your reactants will be copper (Cu) and silver
