Professor Tolentino Maria Oyervide EXPERIMENT #4 IONIC AND COVALENT COMPOUNDS Abstract: This experiment was divided in four steps to find the electrical conductivity of covalent and ionic solutions. There were four unknown solutes A‚ B and C. Each had a specific weight and was dissolved in a certain amount of solute to form either the covalent or ionic solution. Covalent compounds are made up of molecules which are electrically neutral. Ionic compounds are composed of ions‚ which are positively

Jennifer Obrien Date: 11/ April 11‚ 2013 Abstract Inexpensive‚ affordable food is a person’s wants. If find some ways to solve this problem‚ keep food quality and price. So‚ in this paper discuss the solution of how to strike a balance between inexpensive‚ affordable food and healthy‚ quality food. Firstly‚ according to international trade‚ people can import some healthy food from other country‚ which place has lower labor. So‚ people can control the

to observe the hypothesized correlation between ionic strength and degree of ionization of a weak acid‚ while determining the factors that would impact the degree of ionization using measurements of pH. It was initially required to prepare standard 20-mL solutions of varying concentration of acetic acid for use in the rest of the experiment. One solution of CH3COOH was supposedly developed to be 2.00M‚ however it is highly possible that the solutions of CH3COOH were not exactly the expected concentration

CHAPTER 10 CRITICISMS OF ABSORPTION COST SYSTEMS: INCENTIVE TO OVER-PRODUCE P 10-1: Solution to Federal Mixing (10 minutes) [Explaining absorption versus variable costing] Variable costing writes off to income all fixed manufacturing costs incurred during the year. Absorption costing prorates the fixed overheads between units in inventory and units sold based on machine hours. Absorption costing net income is higher than under variable costing by $1.2 million. This means that inventories

Electrolytic Solutions Solutions are sometimes grouped according to their ability to conduct electricity. Substances whose solutions conduct electricity are called electrolytes and those that do not conduct electricity are called nonelectrolytes. Also electrolytes can be strong or weak. Under strong electrolytes we have NaCl and CaCl2 which are ionic compounds‚ HCI‚ HNO3‚ HBr and H2SO4 are under acids and NaOH‚ KOH‚ and LiOH are under bases. Weak electrolytes are ionic compounds and slightly

Role of Internal Audit Function Nano Circuits Inc‚ is a publicly traded company that produces electronic control circuits‚ which are used in many products. In an effort to comply with SOX‚ Nano is in the process of establishing an in-house internal audit function‚ which previously had been outsourced. The company began this process by hiring a Director of Internal Audits. Nano Circuits’ CEO recently called a planning meeting to discuss the roles of key corporate participants regarding the implementation

Conductivity Solutions Abstract: We produced conductivity tests in water and other various solutions with a computer faced Conductivity Probe using the unit of microsiemens per centimeter (uS/cm) to find out which solutions had a high conductivity and which solutions had a low conductivity. Many different solutions vary in conductivity due to the ratio of ions. Different levels of ions have an impact on conductivity because of the different charges and different types of bonds. Conductivity is

CHAPTER 5 Merchandising Operations and the Multiple-Step Income Statement ANSWERS TO QUESTIONS 1. (a) Disagree. The steps in the accounting cycle are the same for both a merchandising company and a service company. (b) The measurement of income is conceptually the same. In both types of companies‚ net income (or loss) results from the matching of expenses with revenues. 2. The components of revenues and expenses differ as follows: | | Merchandising | | Service | RevenuesExpenses
