OBSIDIAN HYDRATION There are two ways of Obsidian Hydration. One is to determine if the artifact is older or younger as the other is a calendar date of AD/BC being used. The decision of which one to use is relative or absolute dating depends on the environment’s condition. The dating of Obsidian Hydration artifacts‚ which is based on the fact that a freshly made surface of obsidian will absorb water from it’s surroundings to form a measurable hydration layer. For example‚ cracking of the lava

Benefits of Hydration The body is made up of around 75% water. Keeping the body adequately hydrated is a must to ensure good health especially in athletes. Sometimes proper hydration is difficult for people if they do not prefer the taste of water. This can lead to serious problems with their health. Determining your hydration can be simply done in two ways. One way to determine your hydration is to examine your urine. If you are properly hydrated it will appear pale yellow or sometimes clear

Experiment 23: Synthesis of an Alkene April 5‚ 2013 Purpose: Results and Discussion The weight of our n-Butyl Bromide sample (actual yield) was 0.09g. The percent yield was found to be 4.38%. Only 0.09g of the theoretical 2.055g yield was obtained. The boiling point was 104° C‚ which is higher than the literature value of 101° C. This is due to the sample being somewhat impure‚ as impurities tend to increase boiling point. When IR spectroscopy was performed‚ there were no OH stretches

Comparing alkanes and alkenes Aim: Is cyclohexane more or less reactive than cyclohexene in the presence or absence of light Hypothesis The cyclohexene will reactive the fastest because being an "ene" it has a electron rich area making it more reactive than cyclohexane but neither one of the will react without light Materials * 4x 250ml conical flasks * 2 rubber stoppers * Aluminium foil * Cyclohexane * Cyclohexene * Bromide water * Measuring cylinder

Chemistry Lab Report Water Hydration Introduction: A hydrated crystal or hydrated occurs when water becomes tightly attracted to a metal salt base on it’s polarity. The water molecules maintain integrity as molecules‚ however they are considered to be part of the formula of the hydrate. When the hydrate metal salt crystal is heated‚ the attractions to the water are broken by the heat energy and the water escape from the crystal. After heating the salt crystal is called as anhydrous‚ which

Exercise 5 Comparing the Reaction Rates of Alkanes and Alkenes Group # 4 Members: Pangan‚ Sam Margarette Perales‚ Angelica Ibay‚ Sophia Irigan‚ Sharien May Sorensen‚ John Antonio Ocan‚ Emmanuel Submitted to: Ms. Ginalyn Cuenca Mr. Neil Abreo Date: December 6‚ 2012 Introduction Alkanes are hydrocarbons with only single bonds between the atoms. Saturated hydrocarbon is the other term for it. They are used as fuels because they are non-reactive and also do not conduct electricity

Lab Report 1 Introduction: Proper chemical formulas entitle many challenges such as the Law of Multiple proportions that states that there may be more than one plausible mole ratio for the elements in that compound. However if we determine the mass of each element in the compound we will be able to get the true chemical formula. In this experiment‚ we used the law of definite proportions to find the chemical formula for a hydrated compound containing copper‚ chlorine‚ and water molecules

The Effects and Benefits of Proper Hydration on the Human Body The essentiality of water for life is inarguable. It makes up roughly sixty percent of the human body and affects every aspect of human health. Humanity depends on water for survival‚ but staying hydrated is essential for so much more than just keeping us alive. The benefits of drinking recommended amounts of water‚ or staying hydrated‚ can be seemingly endless. Something as cheap‚ easy‚ and effective as drinking eight glasses of water

Today‚ I will be arguing the claim that withdrawing artificial nutrition and hydration is not morally different from other types of life-sustaining treatments. I will cover what each procedure is‚ how each procedure is performed‚ and the risks/benefits of these procedures. With that information‚ I can assess how each of these treatments
