CHAPTER I BACKGROUND OF THE STUDY Solid waste disposal is both an urban and rural problem. Person is a potential generation of waste and thus a contribution to this problem. to generate is one thing‚ the type of waste generated is another and now also the way of generated waste is to manage or dispose of it’s quite different issue. Solid waste is any material which comes from domestic and industrial sources from human activities which has no value to people who possess it and

The goal of corporate governance is the increased accountability of the company and acts as a preventative measure for any corporate disaster. A solid corporate governance is of utmost importance and it should act as a an internal affairs unit of the police department who handles and removes problems with extreme measures. Meetings with internal members must be held to address the needs of the affected

DISTILLATION ABSTRACT Distillation‚ one of the most significant method for separating a liquid mixture and its components‚ is a process that relies on differences by the ease of vaporization of the components. The purpose of this process is either the separation of a mixture of volatile components from nonvolatile materials is carried out by a simple distillation in which the material is placed to distill and heated‚ the vapor from the substance is removed and condensed. In this activity

Over the last decade‚ drinks containing high amounts of caffeine‚ sugar‚ and other ingredients that increase energy have been rapidly growing in popularity. Clearly these beverages are known as energy drinks. Energy drinks have gotten so popular that it is extremely rare to find a convenience store that doesn’t sell a variety of them. Students use energy drinks to cram the night before a test‚ athletes use them

High Performance Liquid Chromatography (HPLC) Instructor: Dr. Hüseyin BOZKURT High Performance Liquid Chromatography (HPLC) is one mode of chromatography‚ the most widely used analytical technique. Chromatographic processes can be defined as separation techniques involving mass-transfer between stationary and mobile phases. Present day liquid chromatography that generally utilizes very small packing particles and a relatively high pressure is referred to as high performance liquid chromatography

The Purity and Purification of Solids Recrystallization ABSTRACT In this experiment‚ impure adipic acid is purified though recrystallization. The impure adipic acid is dissolved in a solvent. After cooling it is ran through a vacuum filter to separate any moisture. The dry crystals are then weight for percent yield and the melting point range is taken to test the purity. There were two different trials ran in this experiment. The difference between the two was the addition of charcoal in

THE PURITY AND PURIFICATION OF SOLIDS MELTING POINTS ABSTRACT Melting points of different mixtures of naphthalene and biphenyl were examined in this lab. Samples of these various mixtures were collected and tested by different individuals in the lab in order to find the eutectic point of biphenyl. Unknown substances were then tested using the mixture melting point method in order to determine their identities. INTRODUCTION The melting point of a solid is the temperature where the substance

PARTICIPATION OF THE YOUTH IN THE SOLID WASTE MANAGEMENT OF BAGUIO CITY : An Impact Study Background of the Study The growth of the world’s population‚ increasing urbanization‚ rising standards livings‚ and rapid development of technology have all contributed to an increase in both the amount and variety of solid wastes generated by industrial‚ domestic and others activities (UNEP‚ 1991 ). The problem of dealing with greater volumes often more dangerous waste material‚ are particularly acute

Determining the Molar Mass of a Volatile Liquid Purpose: The purpose of this lab was to find the molar mass of a volatile liquid. Data Table: Mass of Test Tube and Stopper (g) | 10.864 g | Barometric Pressure (mmHg) | 749.31 mmHg | Temperature of Boiling Water (C) | 97.1 C | Mass of Test Tube‚ Stopper‚ and Condensed Liquid (g) | 10.890 g | Volume of Flask (mL) | 9.90 mL | Calculations: 749.31 mmHG*1 atm760 mmHg= .98593 atm 9.90 mL*1 L1000 mL= .00990 L 97.1 C+273=370.1 K Substituting
