principles of the ideal gas law to solve for n or the number of moles carbon dioxide produced, and compare the amount found using the ideal gas law to the actual amount. In order to complete this lab it's necessary to understand the apparatus below. By filling the Erlenmeyer flask completely full with water the mass of CO2 gas in the top of the flask can be determined. Since the combination of sodium bicarbonate and oxalic acid produces CO2 gas, this gas then moves from the gas generation bottle
Vapor is the gas that forms from the vaporization of a volatile liquid. Dumas or vapor density was the method used and is done by measuring the mass of the vaporized liquid and the volume occupied by the vapor. Ideal gas law was the equation used to solve for the molecular mass of the unknown volatile sample. The purpose of this experiment is to determine the molecular mass of a substance from measurements of the density of its vapor. For the methodology, water was heated to boiling. Cap was prepared
hand corner (no binders or clips). Don’t turn in pages where you have scratched out or erased excessively, re-write the pages cleanly and neatly. All problems are equally weighted. Assume we are working with “normal” pressures and temperatures with ideal gases unless noted otherwise. Make sure you list all assumptions that you use (symmetry, isotropy, binomial expansion, etc.). 1. A container has one wall which contains many small holes, and outside the container is vacuum. If the container is filled
In this experiment, there were several objectives. First, this lab was designed to determine the difference, if any, between the densities of Coke and Diet Coke. It was designed to evaluate the accuracy and precision of several lab equipment measurements. This lab was also designed to be an introduction to the LabQuest Data and the Logger Pro data analysis database. Random, systematic, and gross errors are errors made during experiments that can have significant effects to the results. Random errors
through analysis and application. An example of this can be explained through a quick synopsis of my gas law unit. This unit began with a review of kinetic molecular theory. Particle behavior of gases was modeled using a ball on a stick. Each student received this particle model and the room turned into a scaled up model of a gas at the particle level. The students would mimic the behavior a gas particle when different variable were changed. This allowed them to explore what happens at the particle
-------------------- Pressure The three scientists Boyle, Amontons and Charles investigated the relationship between gas, volume and temperature. Boyle discovered that for a fixed mass of gas at constant temperature, the pressure is inversely proportional to its volume. So in equation form this is: pV = constant if T is constant Amontons discovered that for a fixed mass of gas at constant volume, the pressure is proportional to the Kelvin temperature. So in equation form this is: p µ T
gasoline/air type of mixture to a new volume, compared to the volume it had when the piston was rotated to the top of its socket. The typical car has a 9 to 1 compressibility ratio, but this porsche has about 7 to 1 compressibility, which can mean the gas to air mixture in the cylinder is compressed by a factor of 7. The second Property I would like to outline in gases is expandability. Anyone who has walked into a bathroom where many people have just taken a number 2, have experienced the face that
and Background : The molar mass of a gas relates to the number of grams in one mole of that particular gas and all molar masses can be found on the periodic table of the elements. The objective of this lab is to compare the theoretical value of butane gas’s, C4H10 (g), molar mass with an experimental value where the gas from a lighter was released and measured by testing if the water displacement method, where a graduated cylinder is inverted in water and gas is released beneath it and trapped in
advantages and disadvantages, and how these devices produce digital signals will be discussed in this task. Vapor Pressure Thermometers The system of a Vapor Pressure Thermometers contains both vapor and liquid but it is still considered as a type of gas filled instrument. A bulb is used to store the mixture of both phases, and it is this bulb that is suspended into the medium whose temperature needs to be measured. This bulb is connected to a bourdon tube which measures the vapor pressure of the liquid
Opposing Ideals in James Joyce's A Portrait of the Artist as a Young Man Stephen Dedalus, of James Joyce's A Portrait of the Artist as a Young Man, is constantly torn by two opposing ideals. One is that which the institution of the Irish Catholic Church imposes on him, and the other is insisted upon by his independent thoughts and feelings. Stephen chooses between these two ideals, and he rejects the religion offered him by his upbringing and early education in favour of individualistic thought
Aim: - An experiment on how a volume of nitrogen gas is affected by the pressure exerted on it. INTRODUCTION: Gases are composed of molecules and are not held by intermolecular forces of attraction. They move about in random directions constantly colliding with one another and with their container walls without loss of kinetic energy. Thus, the collision of gases is said to be elastic since kinetic energy is not lost. As collision between gas particles become faster and more frequent, the impact
Gas Laws Lab Report CHM 131 – 500A *Scott Futrell Brittany McBill Ellen Beattie This laboratory experiment focuses on The Gas Laws of Robert Boyle and Gay-Lussac. Boyle’s Law defines the relationship that occurs between the pressure and volume of a confined gas. Gay-Lussac's law explains the relationship that occurs between the temperature of a gas and the pressure. The first experiment monitors the pressure of a gas while the volume changes. The second experiment monitors the pressure while the
On earth, substances tend to exist in one of three phases; either a solid, liquid, or gas. While solids and liquids have defining factors such as volume, and for solids only, a shape, gases exhibit neither of these. Gases naturally take the shape of and expand into the volume of the container, and change when placed in different surroundings. As gases are constantly moving around and colliding with the walls, they exert a force, or pressure, on the walls of its container. Pressure is one of the characteristic
fluid is ideal i.e zero viscosity. The flow is steady. The flow is incompressible. The flow is irrotational. p/ρg+ v^2/2g+ z=Constant………………………………Eq(6) Where, p/ρg = Pressure energy unit weight of the fluid. v^2/2g = Kinetic energy per unit weight. z = Potential energy per unit weight. Bernoulli’s Equation for real fluid The Bernoulli’s equation was mainly derived for ideal fluids
Gas is one of three states of matter. The gas state is composed of a group of molecules that move freely, independent of each other. There are certain properties that define gas and separate the state of matter from the other two states: solid and liquid. Many different energies, forces, and amounts greatly affect the behavior of any type of gas. These differences consist of pressure, temperature, volume and even the number of molecules of a gaseous element. There is a mathematical relationship
Traditional Western and Disney Ideals as Seen in Mulan Fairy tales have been a long tradition in almost all cultures, starting as oral traditions to and gradually evolving into written texts intended for future generations to enjoy. Today, a common medium for relaying these ancient stories is through animation. The Walt Disney Company is probably the most well known for its animated portrayals of many classic fairy tales. These fairy tales are considered, by fairy tale researcher Justyna Deszcz
Hollowness of European Ideals Exposed in Heart of Darkness and The Hollow Men Kurtz occupies a peculiar position in Conrad's Heart of Darkness and T.S. Eliot's "The Hollow Men." "Mr. Kurtz, he dead" is the epigraph to "The Hollow Men." Eliot draws an obvious allusion to Kurtz, the morally hollow man in Heart of Darkness. Left to his own devices, Kurtz commits appalling acts such as shrinking human heads and performing terrible sacrifices. Kurtz is armed with only the dubious sense of moral superiority
Biblical Figures and Ideals in William Shakespeare's Richard II William Shakespeare's Richard II tells the story of one monarch's fall from the throne and the ascension of another, Henry Bullingbrook, later to become Henry IV. There is no battle fought between the factions, nor does the process take long. The play is not action-packed, nor does it keep readers in any form of suspense, but rather is comprised of a series of quietly dignified ruminations on the nature of majesty. Thus, the drama
The Values, Ideals, and Actions of Fanny Fern Literature from the 1820âs to the 1860âs brought attention to the expanse of the American experience and gave rise to many unique voices. Some of the best writers of this era challenged their fellow citizens to live up to the ideals that the founding fathers had written into America's sacred documents. The voices that cast these challenges are as varied and wide spread in their approach as this nation's natural boundaries are diverse. Fanny Fern
Because people do not freely choose and follow their values, society creates ideals that control their views in life. These ideals are supposed to maintain order in society by showing everyone their place, but these ideals displace what society should stand for and prevent people from freedom. Should people follow societybs norm or become existentialists and think on their own? Society has set limits on gender roles with ideals such as male privilege and patriarchy. Patriarchy is the political structure
