Ideal gas

Molar Volume of a Gas Lab The purpose of the lab was to do an experiment to determine the molar volume of hydrogen gas at standard temperature and pressure, or STP. To start the experiment, a beaker was filled with water and then a cage was created with a copper wire. A piece of magnesium was cut and placed inside the cage in order to keep the reaction going until all of the magnesium reacted with the hydrochloric acid. The eudiometer tube was filled with 15 mL of hydrochloric acid and water…

learning and exploring in physical activies such as sports and art. 2.What are the primary ideals that the utopia or dystopia is designed to achieve ? One of the primary ideas was to strived to get rid of difference and materialism through strict uniform and inhuman authorianism. One of biggest ideals I noticed was communitarism and family was very important in utopia. Social order was another primary ideal because it lead to a more productive society and this was a way to make sure that…

double lives as Ernest creates the concept of ‘Bunburying’ as said in the play. Used as a means by which people escape from the stifling routine and responsibilities of a rigid society. In the play both Cecily and Gwendolen speak about how their “ideal has always been to love someone of the name Ernest. There is something in that name that inspires absolute confidence” (Gwendolen, p.15). This clever use of language from Wilde depicts how the two women are acknowledging what a delightful name…

fixed mass of gas held at a constant volume, which pressure divided by temperature is a constant value. The gas has initial pressure and final pressure of Pi and Pf respectively, and initial temperature and final temperature of Ti and Tf respectively. Therefore, the equation below is obtained: Pi/Ti=Pf/Tf Where, Pi = Initial pressure Pf = Final pressure Ti = Initial…

chemistry other units that are equivalent are atoms, formula units, and molecules. Gas Laws 3.How is the combined gas law used to calculate differences in pressure, temperature and/or volume for a fixed amount of gas? This is a combination of three different gas laws that give variables for pressure, temperature, and volume that can find the amount of a…

had to take place. After, the combined gas law had to be utilized and manipulated to find the volume and divide that volume by moles of magnesium. Being close to the theoretical value, 22.4L, it verifies that one mole of all gases occupy 22.4L in any container under standard temperature and pressure. This information could be valuable in many ways. For example, it proves Avogadro’s Law which states that at a standard temperature and pressure, one mole of any gas will occupy the same value which…

release rate model. The cylinder gas is considered as a spatially homogeneous thermodynamic system occupying in a single zone for the compression, expansion, intake, exhaust processes and two zones (burned and unburned zone) for the combustion process. The instantaneous composition of cylinder gases are obtained from the mass fraction of fuel burned. The instantaneous thermodynamic properties are computed by the established equations [20-21, 28]. The instantaneous gas properties are calculated…

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…

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…

In this lab experiment, we will be using an unknown volatile liquid in order to understand the direct relationship between the molecular weight of a gas and its vapor density, which will help us determine the molecular weight of the unknown. The necessary tools that are essential in this experiment include: a balance, watch glass, two pieces of foil (2.5x2.5 inches & 3x3 inches), boiling chips, a ring stand, a thermometer, a bunsen burner, and an 800mL beaker. During this experiment, we have to…
