Isotopic analysis is one of many methods used by archaeologists to look at how past cultures and societies lived and were organized. The stable strontium isotope is one of these, and is primarily (with other isotopes) to look at diet and mobility. The measured value in strontium isotopic analysis is the ratio of the natural abundancy of two of strontium’s’ isotopes; naturally occurring 86Sr and radiogenic 87Sr that is derived from the decay of rubidium-87 (Bentley 2006; Hodell et al. 2004; Price

This prospective clinical study was conducted in Department of Oral and Maxillofacial Surgery, Ragas Dental College and Hospital, Chennai, from April 2014 to October 2016. 40 healthy patients requiring surgical extraction of impacted mandibular third molars and fulfilling inclusion criteria were included in the study out of which 23 were males and 17 were females. The nature and number of the diagnostic investigations required, the clinical procedure about to be performed, the duration of the treatment

Christina Cox Your Life as a Microbe project September 1, 2016: My name is strep. Streptococcus Mutans to be exact. I live in a diverse community but my family make up about twenty percent of the world we live in. Our home is called mouth. We have lived here for as long as I can remember. From what I have been told we lived here before there were even homes for us. As a baby our host was kissed by a caregiver who transferred my family to our host. I wasn’t around yet but I hear we had to live down

The Art of Extracting a Molar There are several procedures that can be performed in a dental office. The one that will make a patient weak at the knees is an extraction. A patient may think this procedure is gruesome and scary. However, an extraction is easy, magical, and interesting for me. The first thing you need is a patient who needs an extraction. An x-ray machine, dental film, and lastly the x-ray needs to be developed, I will then take it to the dentist for his assessment. I will take the

Introduction The objectives of the Molar Volume of a Gas Lab are based on an understanding of the creation of a gas and how to measure that volume. Based on the chemical reaction Zn (s) + 2HCl (aq) —> ZnCl2 (aq) + H2 students have to produce a determined volume of hydrogen gas produced from a predicted amount of zinc metal and to evaluate the results based on percent error, technique of experiment, and procedure quality. In order to complete this lab students must have a well rounded understanding

which are coloured, absorb the light depending on how concentrated it is and this produces an electronic reading from the photometer which is the absorbance value. The maximum absorption was found for both solutions and was used to calculate the molar extinction coefficient of methylene blue. An unknown concentration of methylene blue was calculated by using

The purpose of this experiment was to demonstrate how to calculate the molar mass of a volatile liquid using the ideal gas law. By vaporizing a small sample of acetone and condensing it into liquid while measuring temperature, pressure, volume, and mass, the number of moles of the gas substance and its molar mass can be calculated. An accurate calculation of the moles of acetone gas was allowed due to the hole in the foil of the test tube, which ensured that excess oxygen was driven out of the test

The primary goals of this experiment concern expanding upon the concept of molar mass and its applications to the study of chemistry (Beran, 2014). To this end, the effect of an unknown solute on the freezing point of a solvent, cyclohexane, was measured and noted in order to determine a positive or negative relationship between the two variables (Beran, 2014). Additionally, the molar mass of the nonvolatile and nonelectrolyte solid solute was ascertained (Beran, 2014). Introduction: When one examines

Mateo Castro April 3, 2013 Lab Partner: Unur Abdul Kader T.A: Katie Experiment 22: Molar Solubility, Common-Ion Effect Abstract The purpose of this experiment was to determine the molar solubility, the solubility constant, and the effect of a common ion on the molar solubility of calcium hydroxide. To accomplish this the experiment was split into two parts; part A and Part B. in Part A of the experiment a standardized 0.05 M solution of HCl was titrated into a 25 mL solution of saturated

difference I’m tempature it could spark a new way to do things in this economic system we have. Footnote – substance Is the molecular weight in grams. Molar Mass is basically in grams per mole for example salt has a molar mass of 5.8g per mole. The mass of an element refers to 6.0221415x1023 molecules of the substance. Molar Mass helps us figure out how many grams per mole we need to do this project and it helps us know how much we need to put into the solution. If you don’t Find
