of water and it is important to determine if specific sites represent a renewable or a minable resource. Groundwater age at a specific site is useful in determining the rate of groundwater recharge or an acceptable rate of water harvesting in order to not completely deplete an aquifer. Chemicals and isotopes that are dissolved in ground water can be used to determine the apparent age of ground water. These chemicals and isotopes are called age-dating tracers. The apparent age of ground water is considered
Introduction The present condition of our country regarding the use of plastics demands that people explore other means whereby proportionate products can be produced out of raw materials which are commonly disregarded. One of these is the utilization of solid wastes which could yield excellent useful results. Largely an agricultural country, Philippines provides various local raw materials, the utilization of which may lead to the country’s industrialization. Philippines provide ample farm products
planet to begin overheating. With the introduction of CFC's and Carbon Dioxide into the atmosphere we've managed to raise the temperature of this vast resource. Even more ignorant is our failure to learn from our mistakes. Now, through thermal pollution (the introducton of waste heat into water), we've began destroying the womb of all life-the earth's vast water network. The Causes: There are three major causes of thermal pollution. the use of water as a cooling agent deforestation
Introduction: In order for this experimental investigation to be conducted successfully with maximum efficiency, chemical theories must be accurately applied. For this investigation, various concepts and theories will be discussed and applied to the two methods- gravimetric and colourimetric- of analysing the precipitate and solution created. One specific variable will be chosen to be manipulated in order to study and analyse. From this, the most effective and accurate method of analysis of percentage
would say, “just kidding I learned my lesson.” I made a lot of mistakes in my first OHSC0 writing assignment, the main one being to keep my essay focused even if it means leaving out what I had seen as comic relief. I believe just this change would have made room for me to correct most of my other mistakes as one of my biggest problems in this essay was editing it down to two pages. One of the main comments about my essay was that I should be, “including clear definition of terms in the scientific process
Introduction Acid-base extraction is a very useful technique in organic chemistry. It is used to separate organic compounds from each other. The idea is that most of organic compounds will be more soluble in organic solvents than they are in water (1). The extraction, in its most basic form, will result in unequal distribution of solute between two immiscible (not forming one mixture when added together) solvents (2). Since both of the solvents are immiscible, two separate layers
wide range, and lower value than that of the theoretical melting point of 136°C, it was assessed that the prepared aspirin was impure. INTRODUCTION Aspirin is a most widely sold over-the-counter drug. It has the ability to reduce fever (an antipyretic), to reduce pain (an analgesic), and to reduce swelling, soreness, and redness (an anti-inflammatory agent). One of the first recorded accounts for the discovery of aspirin appeared in England, in 1763, crediting the bark of willow trees with a beneficial

These create a very negative impact if not disposed properly. In the state of Illinois the implementation of the Federal
POLYTHENE POLLUTION INTRODUCTION The pollutants that are of major concern in today’s world are non biodegradable pollutants that do not degrade or degrade very slowly in the natural environment. Polythene pollution is an example of non biodegradable pollution and they persist on our earth years after years affecting even future generation. Polythene pollution is mostly created by polythene bags, plastic syringe, pesticide containers, medicinal bottles. [pic] Effects of Polythene Pollution
of Different Fluids on Urine Volume, Concentration, and pH Introduction The examination of urine is called urinalysis, which is a diagnostic method for assessing renal function and diagnosing various types of pathophysiology involving not on the kidneys but other organs and tissues as well. We will be focusing on the kidneys for this experiment. The kidneys play an essential role in regulating of extracellular concentrations of water, electrolytes, and certain end product of metabolism; additionally
