14.1- FCD4 Experiment 6 Determination of the Molar Volume of A Gas and The Universal Gas Constant Abstract This is the summary of the whole experiment. State an overview of the experiment (i.e, objectives, procedure, relevant results. This part should be contained only in a single paragraph; limit to 200-300 words.) Introduction Experiment 6 aims to determine the Molar Volume of a Gas, which is the volume occupied by 1 mole of gas experimentally from the Ratio of the Volume of Gas Generated to
Independent Variable: Three different wind velocities Hypothesis: The gas pressure sensor is going to sense higher gas pressure around the leaf as transpiration rate increases. The higher the wind velocity is the lower the gas pressure. This is related with transpiration because if you have low gas pressure then you have a lower rate of transpiration. Materials: • Vaseline (Petroleum Jelly) • Vernier Lab Quest • Gas Pressure Sensor • Fan with different type of settings (three) • Three leaves
Atmospheric pressure and the mass of oxidizer in the air are directly proportional to each other. The density of air at a given atmospheric pressure is given by ρ=P/(R_s T) For an ideal gas where P is the absolute pressure, R is the gas constant, and T is the temperature. The volume (V) occupied by n moles of any gas has a pressure (P) at temperature (T) in Kelvin. The relationship for these variables, What we can understand from this is that the concentration of air in a given volume increases
chemical reaction. It consist consists of a chamber of a chamber that is air and water tight, with a gadget that allows the introduction of high pressure O2 gas and administration of current through a wire (1). A known quantity of a substance is compressed into a pellet, and it wrapped with a conductor wire was then placed into the bomb body (1). Oxygen gas was pumped into the chamber to a pressure of 12 atmospheres; the bomb was submerged into 2-L of deionized water, with a thermometer measuring water temperature;
Purpose: The purpose of this experiment was to identify what the unknown metal was by determining what the atomic mass was. To obtain the atomic mass of the unknown metal, the number of moles of H2 gas produced from the reaction was calculated. Introduction: This lab was an application of the kinetic- molecular theory of gases. According to this theory, it stated how gaseous particles are in a constant motion where they go at random speeds as well as directions.1 According to Thomas Graham, a Scottish
Using gas chromatography, the liquid mixture was identified and analyzed. For simple distillation, the mole fractions for hexane in vials 1, 2, 3, and 4 were 0.7533, 0.6366, 0.5459 and 0.2668, respectively. The mole fractions of heptane were 0.2467, 0.3634, 0
The hypothesis was supported. For example, test tube A experienced an increase in temperature while oxygen gas created foam caused by the bubbles that escaped. After the hydrogen peroxide was tested with the liver, new hydrogen peroxide was added to test tube A with the reused liver. As a result, the enzyme was reusable since oxygen gas was released during a change in temperature. However, test tube B experienced no reaction when used hydrogen peroxide was added to an unused
who was sent to the gas chamber and who was allowed to live, Mengele is also widely known for his famous fascination with twins. Although Mengele has a reputation for being a heinous mistake for a human being, numerous accounts given by twins from Auschwitz testify that he was a friend or a fatherly figure to them, and that he protected and cared for them. Mengele caused the deaths of thousands of men, women, and children during the Holocaust, performed unthinkable experiments on helpless children
There is no ideal way to overcome the problem of waste disposal, all options in waste management have their own impact mainly emissions from landfilling. Landfilling accounted for almost 5% of total global emissions of greenhouses gas that has an impact 20 times higher than carbon dioxide. The use of proper waste management can make a major contribution towards a sustainable future. Creating a strategy for the prevention of waste is the most important thing. A country without a strategy will not
process of photosynthesis. In theory, when an aquatic plant is placed in a solution containing a source of carbon dioxide (CO2), in the presence of light of appropriate intensity, the plant will photosynthesise and produce bubbles of oxygen-containing gas. These bubbles can be counted and the rate of bubbling can serve as an indication of the rate of photosynthesis. When the light intensity is increased, the rate of bubble production should increase. Decrease the light intensity and the rate of bubbling
