Introduction: The method for purifying solids is done by observing the melting point. This is important because if there is an impure substance the melting point would be depression and the melting range would be broader. By finding the melting point of a known substance one can then observe an unknown substance’s melting point to see if the points are the same and try to figure out the unknown. Experimental Section: The first known substance we used was Biphenyl. 68 degrees Celsius is the

Determining the accuracy of varieties of pipettes by weighing and finding the density of a liquid Abstract Different varieties of pipettes (P100‚ PR1000 pipettors and a serological pipette) along with a weighing balance was used in this investigation to check the density of an unknown liquid by first finding out what the liquid weighed and plotting a graph of the mass in grams against the volume of the liquid used in micro litres (µl) and finding the gradient of the graph (∆Y/∆X). Most of the standard

Global Municipal Solid Waste Management Market 2014-20180280035Municipal solid waste management generally refers to the management of solid waste from residential societies‚ streets‚ public places‚ commercial buildings‚ hospitals‚ and other institutions. Management of these types of waste is mainly the responsibility of municipal and other governmental authorities. Municipal solid waste management is one of the major problems being faced worldwide. Municipal solid waste is a part of the larger universe

Solid waste management is a must because first & foremost‚ it is mandated by law. The law in the form of RA 90031 specifies an effective solid waste management to protect the public health from the spread and/or outbreaks of infectious diseases resulting from unattended solid wastes. Deriquito (2006)7‚ in describing Makati’s successful waste management‚ posits that “solid waste management is a responsibility of the society.” Success in having an effective solid waste management can be attributed

OF DETTOL ANTISEPTIC LIQUID ON THE GROWTH OF E.COLI Background: Escherichia coli are rod shaped‚ gram negative bacteria often found in the gut of humans and other warm-blooded mammals (Jacques & Ngo‚ 2004). It is transmitted primarily through faecal contaminated food and water. Most strains of E. coli are not harmful to humans‚ however some strains are pathogenic and can cause symptoms including diarrhoea (Unknown‚ 2012). The active ingredient in Dettol Antiseptic Liquid is 4.8% chloroxylenol

Thermometer Works - pg. 23 Purpose: What makes the liquid within a thermometer go up and down? Hypothesis: If the liquid is placed into objects of different temperatures‚ then the liquid moves up in the hotter substance and down in the colder substance‚ because of the change in the molecular energy when the water is hot and when the water is cold. Materials: Test tube‚ about 20 mL Isopropyl rubbing alcohol‚ 91% Small cup 2 small disposable water bottles (8 oz.) or 2 small beakers Food

useful for the simple identification of colourless organic liquids and ones that are often found at the scenes of crime. The first test carried out was the Lucas test which was used to identify a variety of alcohols following the contribution of a given solution‚ from carrying this out I could then identify that primary and secondary alcohols were present with one tertiary alcohol also being present however despite this given the colourless liquid that formed it is questionable as to whether the first

To answer this question one must first understand that every politico-economic ideology‚ like every religious belief‚ proclaims that it has the one true doctrine and that all others are entirely different or at opposite ends. In most instances individuals join in voluntary association to act upon those opinions‚ ideas or beliefs which they hold in common. These opinions‚ ideas or beliefs may or may not be based on facts and hence most end with disastrous results. However once ideas have crystallized
