The EOQ Inventory Formula James M. Cargal Mathematics Department Troy University – Montgomery Campus A basic problem for businesses and manufacturers is‚ when ordering supplies‚ to determine what quantity of a given item to order. A great deal of literature has dealt with this problem (unfortunately many of the best books on the subject are out of print). Many formulas and algorithms have been created. Of these the simplest formula is the most used: The EOQ (economic order quantity) or

Formula of a Hydrate Lab Wednesday October 29‚ 2014 Chemistry Honors Purpose This lab was done to determine the percentage of water in a hydrate‚ which was CuSO4 ?H20. Not only the percentage of water can be found‚ the moles of water can be found per one mole of anhydrous salt. An anhydrous salt is a hydrate that lost its water. Using various lab equipment such as burners‚ crucible‚ and balance‚ and techniques such as the mass-to-mole ratio and mass to percentage‚ the percentage of water in a hydrate

Shawn Dubbs Lab 1 The Mole Concept of and the Chemical Formula of a Hydrate Abstract: The objective of this lab was to conduct an experiment to analyze the molar components in alum. This was conducted by heating the alum till the water had evaporated and then determining the number of moles for each component. Then using the these amounts to figure out the empirical formula for alum. Results: In order to determine how much of each separate component a total mass was taken before hand for

Chemical Formulas Review: Nomenclature and Formula Writing Naming Simple Compounds There are four naming systems you should familiarize yourself with to succeed on the SAT II Chemistry exam. The trick is recognizing which naming system to use. Here are the guidelines: * If the compound starts with H‚ it is an acid. Use the naming acids rules. * If the compound starts with C and contains quite a few H’s and perhaps some O’s‚ it is organic. Use the naming organic compounds rules. *

Evaluate the social and economic impacts of the ‘One Child’ Policy in China In the year 1979‚ China was suffering a severe increase in population‚ and because of this Deng Xiaoping (leader of the communist party of China) introduced China to an anti-natalist policy called the ‘One Child’ policy. An anti-natalist policy aims to decrease the crude birth rate and the total fertility rate in a country in order to slow the population growth . This policy generated many social and economical impacts
