Noble gas

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…

Variables Likely impact upon the investigation How the variable will be changed/measured/controlled Independent variable Mass of Baking Soda (grams) Changing the mass of baking soda will impact the volume of gas is produced. The higher the mass, the more gas will be produced, and vice-versa. This will happen as the results of the decomposition of baking soda will be directly proportional to the mass of the baking soda. The independent variable will be altered by changing the amount of baking…

Gas exchange affects all processes of the body because everything in the body requires the gas exchange process to occur. The following are the interrelated concepts with gas exchange according to Giddens (2017); acid-base balance, anxiety, perfusion, nutrition, mobility, and fatigue. Acid-Base Balance is affected in a variety of different ways by gas exchange. For example, with chronic respiratory conditions such as COPD it causes respiratory acidosis which is essentially an increase in…

distillation, to pure octane. The distillation could be completed because part of the solution, hexane, had a lower boiling point than the other, octane, allowing it to evaporate out. Throughout the experiment, four samples were taken and tested by gas chromatography. Gas Chromatography, or GC, was used to analysis the components of each fraction taken during the experiment. Upon looking at the data, the presence of hexane in the fractions decreased, whereas, the presence of octane increased.…

Unstable are for the most part carbon and hydrocarbon-based intensifies that are unpredictable (swing to gas at room temperature. Inaba and Cohen (2007) They incorporate such basic materials as gas and gas added substances, lamp oil , paint(especially metallic paints) , air dusters, acetones , finishes, nail shine remover, spot removers, pastes and plastic bonds, lighter liquid, and an assortment of pressurized canned products. These unpredictable solvents are fast acting since they are…

The goal of this experiment was to use chemistry to analyze an unknown compound and through testing its physical and chemical properties determine what unknown compound that was found in a landfill. This would benefit the Environmental Protection Agency because once they know what the substance was they could determine the best way to remove it from the landfill and if there were any potential safety hazards to beware of while handling the substance. This would prevent any accidents that may…

Hobbytown Rocket V.S. Chemistry Rocket Research Paper A Rocket is a projectile that can operate on it's own without oxygen by the combustion of it's contents. Rockets are particularly interesting because it has transported mankind where they have never been before. That is why this project is on Rocketry, but with small scale rockets. The purpose of this project is to see if a homemade Chemistry Rocket, fuel made of baking soda and vinegar, can equal the endurance and/or the height of a…

In this lab, two methods of distillation (simple and fractional) were utilized to separate a mixture of volatile compounds (cyclohexane and toluene). As a first observation of the results and data generated, looking specifically at the simple and fractional distillation curves, it seemed that the fractional curve obtained was not as expected. In fact, it was not very different from the simple distillation curve, having a gradual positive slope. This means that there was actually not a big…

The objective goal of this experiment is to identify a set of unknown liquids by measuring the liquids of three physical properties which consists of determining the density, solubility and boiling point of the liquids A, B, C and D. Ethyl acetate, methanol cyclohexane and acetone were the unlabeled liquids. In the data analysis the predictions came out to be liquid A for acetone, liquid B is for ethyl acetate, liquid C is methanol and liquid D is cyclohexane. Introduction and Experimental…

Maciej Szwoch Chm 131-005 5/5/18 Writing Assignment Figure 1 [This diagram shows at what temperatures/pressures water changes phases. As shown in Figure 1 (“Interactive Student Tutorial”) above water turns into a gas at 100 degrees Celsius. At 0 degrees Celsius and below it becomes a solid. This diagram makes it easy to see that the energy needed (temperature) to change phases greatly increases] Molality Molality is the number of Moles of solute divided by kilograms of solvent (Tutapoint…
