Xenon is one of the 6 noble gases on the periodic table 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…

“The AHJ is stating I cannot mix residential sprinklers with quick-response sprinklers in a hallway per 8.4.5.3. Is that correct?” We have reviewed NFPA 13, 2016 edition as the applicable standard. Our informal interpretation is that when residential sprinklers are installed within a compartment, all the sprinklers shall be of the residential type. The text regarding this issue changed starting in the 2013 edition of NFPA 13. This states in 8.4.5.3, “Where residential sprinklers are…

What is Sodium cyanide? Sodium Cyanide is an inorganic Compound, it has a formula NaCN. Cyanide actually has a high affinity for metals which can lead to a high toxicity of the salt. Sodium Cyanide has a boiling point of 2,725°F (1,496°C) and it also has a melting point of 1,047°F (563.7°C). A common name for sodium Cyanide is sodium salt of hydrocyanic acid. Cyanide has an appearance of while crystalline or granular powder. This toxin releases a hydrogen cyanide gas which is…

What is the chemistry of hair highlights? Hydrogen peroxide is an ingredient that is included in most commercial hair dyes, it is a cheap, easy way to brighten your hair or bring out your natural highlights. Keep in mind that with any home bleaching or dyeing process, there is a chance of damaging your hair or getting an unnatural looking result. Highlights have been around forever, although not used in the traditional sense. Different methods have been used for centuries. Hair highlights are…

Purpose The purpose of this experiment is to identify the rate constant in kinetics reactions during the t-butyl chloride convert into hydrolyzed. Theory Kinetics reaction analyzes the how fast the chemical reaction occurs when two solution mix together. Chemical reaction is changing their properties and reagents concentration which create new products. There is a titration method to check the kinetic reaction. For example, of chemical equation as aA + bB → cC+ dD This equation describes the…

Aim: - The aim of this experiment is to find out on how the independent variable which is the temperature changes that reaction rate of the magnesium and hydrochloric acid (HCI). Hypothesis: - As the concentration increases, the rate of reaction increases as well. Variables: - The independent variable is the volume of hydrochloric acid - The dependent variable is variable is the volume of the hydrochloric acid and the duration of reaction. - The controlled variables are length of the strip of…

There are five common ways to predict the product of chemical changes. They are synthesis (composition), decomposition, single replacement, double replacement, and combustion. Each can be used for different types of problems based on the equation of experiment presented to you. They can also be found using observations throughout the experiment. You use these base guidelines to write a well balanced equation with physical states and all of the reactants and products that are produced. Our…

Adding distilled water to this mixture will eradicate any traces of salt (sodium ethanoate and sodium sulfate) and remaining soluble impurities when it is discarded (AUS-e-TUTE. 2015.) Any remaining traces of ethanoic acid and sulfuric acid is neutralised by sodium carbonate (as shown in equation 1) (Fischer esterification reaction), which is converted to soluble sodium sulfate, sodium ethanoate and carbon dioxide which is released by inverting the separating funnel, and opening the tap.…
