belonging to group 18. The element was discovered by Sir Ramsay in 1898. Xenon’s symbol is Xe and its atomic number is 54. Xenon’s atomic mass is 131.293 grams. Its boiling point is -107 degrees Celsius, while its freezing point is -112 degrees Celsius. The density of Xenon at 20 degrees Celsius is 0.005887 grams per cubic centimeter. Xenon has 21 isotopes Xenon is described as being completely colorless and odorless, however when excited by electrical discharge Xenon will emit a blue…

First off, water has a very high boiling point, one hundred degrees Celsius, relative to its small molecular weight at roughly eighteen grams. Water requires more energy to break hydrogen bonds before it can boil. Freezing works the same way as boiling, but in reverse since it is going to colder temperatures, zero degrees Celsius to freeze, rather than hotter. These extremes in freezing and boiling points allow the molecules to freeze or boil very…

is no major change in properties of Kevlar. When exposed to arctic conditions. As shown in the table Kevlars tenacity, and tensile strength do not change that much. (DPT Kevlar Technical Guide revised) At temperatures of -320 Fahrenheit, or -196 Celsius Kevlar does not embrittle or degrade. Kevlar is mostly heat resistance, but it can ignited. However, burning stops once the ignition is removed. Pulp or dust may continue to smolder once ignited. When Kevlar is being burned, there is no…

week after the Didinium predators were added. The experiments were run with two main factors the temperatures and having a presence or absence of interspecific interactions. There were three different temperature factors were 22, 26, and 30 degrees Celsius that were used in this experiment (Jiang and Kulczycki, 2004). Then the specie interactions had three different sets. The first was the control which was just the one or the other of the bacterivores in the microcosms, the second was both the…

Introduction An enzyme is a protein that functions as a catalyst, it speeds up chemical reactions (Freeman et al. 2017 p. 90). Enzymes are often large globular proteins and are able to hold substrates in specific orientations so they are able to react, the location where the substrate binds with the enzyme and reacts is called the active site and is the location where the catalysis occurs (Freeman et al. 2017). Enzymes activity is often related to the optimal environment for them in respect to…

Danika Ng CHEM 1252 L Exp 12: Thermodynamic Analysis of Chemical Equilibria INTRODUCTION The reaction being done with borax and HCl is an acid base reaction. The K constant expression of the reaction is Kc = [Na^+][B4O7^-2]. A titration is needed for this experiment because when a strong acid with a known concentration is added to a weak base, the unknown concentration of the weak base can be found, which can then find the moles of the weak base, which can then find the Kc. The first law of…

use temperature to find out cold or hot it is in the world. There's three types of temperature scales we use in the world Fahrenheit, Celsius, and Kelvin. Celsius (C) is an Metric scale in which the temperature range between the freezing point and the boiling point of water is divided into 100 equal fractions (degrees). In most parts of the world they use Celsius, in 1970s this was recognized the standardize on metric measurement system. Kelvin is a temperature scale designed so that zero…

One such way of removing caffeine includes distillation, distillation is possible between the two as they have a distance of over 50 degrees Celsius in boiling points. Water has a boiling point of 100 degrees Celsius and caffeine has a boiling point of 178 degrees Celsius. This means if the solution is heated to 100 degrees the water will begin to evaporate but the caffeine will not. The water vapours can then undergo condensation leaving pure water without…

to think why food is measured in Calories. Many nutritionists are not sure of the true origin of the Calorie or why it’s supposed to be capitalized. Traditionally, a Calorie is the amount of energy needed to heat one kilogram of water one degree Celsius. It appears it was first used in engineering and physics, and then found its way in nutrition. With respect to nutrition, it is used to measure the amount of energy food contains. Some historians believe that there is some controversy as to whom…

part of Canada. For example, In the southernmost city in Canada, Windsor, Ontario, where the average temperature is 22 degrees celsius in the summer and below 5 degrees celsius in the winter. We can compare this to another southern city that is a bit farther north, Toronto, Ontario, Where the average temperature is 20 degrees celsius in the summer and below 4 degrees celsius in the winter. Extrapolating this data we can make the assumption that the farther north the city the lower the average…
