Potentially, there have been many hazardous instances where engineers were scrutinized for their actions due to lack of ethical considerations. One of the most destructive case is the world’s worst industrial disaster: Bhopal Gas Tragedy. The trail of this tragedy began in the city of Bhopal located in the state of Madhya Pradesh. The night of December 2, 1984 was nothing out of the ordinary and seemed like any other winter night of central India but it was superficial. An…

used. Both techniques use Gas Chromatography, which is separating mixtures based on their distribution between a stationary liquid phase and moving gas phase (Saferstein, 2011). The Headspace Technique was developed in the 1980’s to aid in explaining the odor compounds found in the air surrounding objects such as plants, flowers and food (Headspace technology - Wikipedia, the free encyclopedia, n.d.) Headspace analysis is the investigation of the components present in the gas, which is found…

This reaction involves very intricate and steps that are critical to understanding the concept of equilibrium as a whole. First, an important concept to understand when describing any reaction is the idea of collision probability. When we examine gas molecules in a 1 cm3 container, there can be billions of collisions per second between neighboring molecules, and even then, maybe only one of these collisions result in a reaction. If any one collision occurs, the only way they will react to form a…

My Element is the Most Important Element (Argon) •Atomic mass 39.948 •Atomic Number -18 •Gas at 298 K •Density-0.0017837 grams per cubic centimeter •Third Noble gas •Chemical Symbol-Ar •It is also obtained from the air as a byproduct of the production of oxygen and nitrogen •It is the third most atmospheric gas •Argon is colorless and odorless •Argon is non reactive and has no effect on living organisms •Makes up 1% of the air around •Argon is found in the earth’s crust…

physical law such as Boyle’s law states that P, the exerted fixed mass of gas at a constant temperature and V, the volume have a relationship. Their kind of relationship is V=f(P) relationship and it is believed that PV go together to remain constant. A water manometer is an instrument used to measure pressure. The model of kinetic theory of gases helps elaborate one of the most difficult…

The main objective of this lab was to collect 〖Co〗_2 gases that were given off by the Alka-Seltzer tablets and to identify experimental masses. The volume of gas was 724 liters, or 723.86 cm and the experimental mass was .0894 grams. A balance scale was used before and after the reaction to record the change in overall mass. First, using the scale, the flask, balloon, and Alka-Setlzer tablets were measured, 259.4 ±.05 Grams were found. What created the “〖Co〗_2 gases to be trapped” were the…

Hydrofracking is a process of natural gas drilling. The purpose of the project in Pennsylvania is to create a clean energy source that’s produced domestically in America (Griswold, 2011). However, with such potential economic growth, there are consequences that affect people who live in close proximity to the production. The ecosystem services that are affected are air and water, including the earth. According to the “Ecosystem Services” (Daily, 1997) article, ecosystem services support life…

The molar heat of vaporization of n-heptane for the rising T and falling T sets of data was 26.10 kJ/mol . This is the energy required to transform a given amount of n-heptane from a liquid into a gas at a certain pressure. In both table 1 and 2, the vapor pressure was gradually increased as the temperature increased. Also, the vapor pressure was decreased as the temperature decreased. This means that the data values that obtained from this experiment were true values. The isoteniscope method…

A filter is something that removes impurities or solid particles from a liquid or gas that passes through it. There has been a total of 76% of deaths due to infections from dirty liquids and poisonous gases. Not many filters do the same job you would like it to do, but with this particular filter it is made to filter out gases, liquids, and solids from a variety of different elements and objects as well as cleaning any object you toss into it. The item's frame is powerful enough to do these…

Purpose The purpose of this experiment was to collect three different fractions of a mixture of hexane and toluene at differing temperatures. From there, the fractions would be measured via gas chromatography to discover the percent composition of hexane and toluene in each fraction with the ultimate goal of having one fraction with mostly hexane, one with mostly toluene, and one with an even mixture of the two. Along with this, there is also the goal of redistilling one of the fractions in…
