In this lab, a hexane and octane mixture was purified, through 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. This was due to the fact that the hexane was evaporating out of the conical reaction vial and collected once condensed in the distillation head. As time progressed, most of the hexane was removed,…

Gas chromatography (like any other chromatography) is a separation technique in which the mobile phase is a gas. This technique is applied for the separation of volatile substances. This method separates a mixture into its components and is used to measure the concentration as well as it identifies the components. GC creates a time separation rather than physical separation which means that the components are separated in time. After they are detected, a chromatogram is generated. Each peak in…

Distillation is a method used to purify a liquid. Distillation is a process of heating a liquid to boiling and then collecting the condensed vapors from the boiling liquid in a different vessel. After the setting up the glassware for the simple distillation I found the boiling points for each four fractions. The boiling point range for the first fraction was 29.3°C to 29.5°C. The boiling point range for the second fraction was 31.1°C to 40.6°C. The boiling point range for the third fraction was…

By using the techniques of simple distillation and gas chromatography to purify and determine relative proportions of volatile compounds in their gas form. Distillation could be described as a process where a mixture was heated until it began to boil, and the condensed vapor was collected. After completing the distillation process, the gas chromatography method could be used to identify the relative components of a compound in a volatile mixture. According to the analysis between the…

last location will be in my bedroom on the top floor with the heat on. This is for the hot environment. The temperature will be at about 100° Fahrenheit. By doing this I will find out in which environment gases expand and contract the most in. The questions I researched were, how does temperature affect gas molecules, how does kinetic energy affect temperature change, and what is the Ideal Gas Law? Matter comes in four different forms, called states: solids, liquids, gases, and plasmas. In this…

Gases, solids, and liquids are the three states that a substance can exist as. A gas does not maintain shape and volume. Gases expand to fit and fill the container. While a liquid maintains volume, but not shape and fits the shape of the container it is placed in. Solids can maintain both volume and shape. When a gas exerts force on the walls of a container, this is known as its pressure. Pressure varies based on temperature and volume. Many gas laws were used within this experiment, such as…

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…

The Ideal Gas Law relates several variables of state of an ideal gas with the following equation: P V = n R T, where P is the pressure of the gas in atmospheres, V is the volume of the gas in liters, n is moles of the gas, and T is the temperature of the gas in Kelvin degrees. R is the ideal gas constant. The Ideal Gas Law is a combined summary of Boyle’s Law, Charles’s Law, and the Avogadro’s Law. This Law works best under low pressure, room temperature (298K) environments because these…

HFOV and Gas Mixtures RES 262 Julia Fussell Sarah Bandy HFOV and Gas Mixtures The type of ventilation I will be discussing is High Frequency Oscillating ventilation. I chose this type of ventilation because of how different it is compared to traditional ventilation. “HFOV uses a constant distending pressure where an oscillatory flow along with clearly defined inspiratory and expiratory phases are generated in the lung”( adhb.govt.). Because the pressure is constant, it is easy to…

Greenhouse Gas Pollution in the United States Whether we like it or not greenhouse gas pollution is inevitably increasing in the United States; negatively affecting all of our daily lives. How many American citizens drive a car? Roughly 34 percent of the nation’s households own at least one car, and every-time a person drives it releases about 24 pounds of Carbon Dioxide into the atmosphere. That is just one example of greenhouse gas pollution, and there are an innumerable amount of other…
