The Absorption Spectrum of Cobalt(II) Chloride Thang Dinh Lab partner: Alex Yang CHM 151 – 102 11/17/2014 Introduction: Many compounds absorb a certain spectrum of visible light. Since Beer’s Law describe the relationship between molar absorptivity and concentration‚ one could use his equation A = kc to find the unknown concentration by the known absorptivity. The graph of absorption spectrum is represented by a linear regression. From the graph‚ one could deduct that as the concentration decreases

Due to a clerical error‚ a company overstated by $50‚000 the amount of inventory on hand at the end of the year. Will net income for the year be overstated or understated? Identify the two accounts on the year-end balance sheet that will be in error and indicate whether they will be understated or overstated. Error: The ending inventory is overstated by $50‚000. Effect on net income: When the ending inventory is overstated‚ then‚ the cost of goods sold expense will be understated as the ending inventory

Agri-environment contract adoption under fixed and variable compliance costs. This report looks at the agri-environment contract adpted by farmers’ to be able to contribute and partake in the enrivonmental schemes through pressure groups and government. It provides disctinct description to the differences in fixed and variable costs. The purpose of explaining the differences were to illustrate how farmers partaking to the project would be different than how much land will be needed to chip in the

3. Trauscht Corporation has provided the following data from its activity-based costing system: The company makes 340 units of product P23F a year‚ requiring a total of 710 machine-hours‚ 80 orders‚ and 40 inspection-hours per year. The product ’s direct materials cost is $40.05 per unit and its direct labor cost is $14.35 per unit. The product sells for $121.90 per unit. According to the activity-based costing system‚ the product margin for product P23F is: A. $9‚223.20 B. $7‚853.60 C

volume-based product costing system. The Overhead costs of Duo plc have been allocated using the Traditional costing system in table 1. The Overhead costs have been allocated using Direct Labour Hours (DLH) of production (Direct Labour Hour absorption approach). That is‚ Total Overhead costs were divided by the addition of all DLHs‚ giving us the overhead rate per labour hour (£10.345). This method was used since‚ firstly‚ it is the basic method of traditional volume-based costing‚ and secondly‚

Activity-Based Costing System A presentation by Ahmad Tariq Bhatti FCMA‚ FPA‚ MA (Economics)‚ BSc Dubai‚ United Arab Emirates Activity-Based Costing Activity-Based Costing System 2 The Concept Activity-Based Costing In contrast to traditional/absorption costing system‚ ABC system first accumulates overheads costs for each organizational activity‚ and then assigns the costs of the activities to the products‚ services‚ or customers (cost objects) causing that activity. Activity-Based Costing System

Differences between Activity-Based Costing and Traditional Cost Strategy Activity-based costing (ABC) is a costing model that identifies overhead activities in an organization and assigns the cost of each activity resource to all products and services according to the actual consumption‚ while traditional costing equally distributes all overhead expenses. Thus‚ an organization employing ABC‚ can precisely estimate the cost of its individual products and services for the purposes of identifying and

Practical 3 ABSORPTION SPECTRA AND THE BEER-LAMBERT LAW The purpose of this practical was to measure the amount of a chemical substance present in a sample. Primarily‚ the aim of Experiment 1 was to measure the absorption spectrum of a particular coloured substance (in this case Bromophenol Blue and Methyl Orange) at varying wavelengths of light. For Experiment 2‚ the process of the experiment focuses on the substance and records its absorption levels at different concentrations. The absorption levels
