Co2 Density Lab

To control the hazard of CO2 leakage, the compression and transport process of carbon dioxide should be isolated and the pipelines should be mended

Carbon dioxide has a less than density of soda, so the bubbles rise. You know this because if you put a balloon on top of the top of the bottle and put pop rocks in. The carbon dioxide will fill up the balloon. Pop rocks and soda make a chemical reaction. The soda is the main part that makes the balloon fill with gases.

Max Heilman Cartesian Diver Project Chemistry 10 Mrs. McCarroll January 22, 2018 Introduction The Cartesian Diver is a pressurized water experiment demonstrating the principle of buoyancy and the ideal gas law. It was invented by Rene Descartes and later documented by Rafeallo Magiotti’s “Renifenza certissima dell’acqua alla compression,” or “Very Firm Resistance of Water to Compression,” in 1648. Descartes was credited as being the greatest French philosopher, mathematician, and scientist of the 17th century. He was also dubbed “The Father of Modern Western Philosophy,” as his writings have been studied for centuries, and are still studied today.

This could include setting up the experiment incorrectly, or a simple

This lab contains two experiments that both test the knowledge of the gas law and how it applies to the state that is necessary to form a cloud and to calculate the rate of effusion of CO2 (carbon dioxide) leaving a balloon. If carbon dioxide is placed into a balloon for a period of time, then the carbon dioxide will effuse out of the balloon at a linear rate, because of the pressure that the gas is placing on the wall of the balloon that will allow it to escape from the balloon's microscopic pores. If a match is placed into a flask with room temperature water and heated water, then the resulting cloud that forms in the heated water will have a higher volume and a higher pressure than the cloud that forms in the room temperature water. The

Research Question: To investigate and compare how different temperature (5℃, 15℃, 25℃, 35℃, 45℃) can affect the concentration of carbon dioxide in soda water through titration with sodium hydroxide solution. Introduction: Carbon dioxide plays an important role in soft drinks. Soda water is manufactured by pumping carbon dioxide into water under high pressure. Carbon dioxide dissolves in water to form carbonic acid, which is the fizz we find in soft drinks. CO2 + H2O ⇌

The CO2 and H2O are released to the environment through the process of cellular respiration. Therefore, the rate of cell respiration can be measured by the volume of oxygen used. The purpose of this experiment

As carbon dioxide is blown into the beaker through the straw the pH level lowers. The universal indicator showed that the added carbon dioxide turned the pH level acidic. If the pH level in the ocean drops to acidic marine life can be harmfully affected. Coral bleaching and the weakening of calcium carbonate shells are both affects of the increase of acidic pH levels. When testing how the pH level affected the shells, we knew a reaction was according due to the bubbling of the shells.

Hypothesis: We think that the more Dry Ice we put in the balloon will make it bigger because as their is more dry ice there will be more gas and carbon dioxide exerted by the dry ice when you put water over it. Design an Experiment: Materials list :- Dry Ice Empty water bottle Water A balloon (preferably colorless) Metric ruler Procedure :- First, grab the water bottle and fill it with about 10g of dry ice.

We waited fifteen minutes and let the sensor collect the carbon dioxide levels inside the bottle. At the end of fifteen minutes, we brought it back into the building and removed the plant pieces. After this first run, we repeated the same exact steps for cedar, boxwood, and a control. For the control, we measured the carbon dioxide levels of a bottle outside with nothing inside it. In order to get the most accurate results possible, we also ran another trial using the same

The purpose of this lab is to use the combined gas law to find the new volume of the can after the temperature has changed. Also in this lab, the volume changes again and it is found using water displacement. The dependent variable in this lab would be the volume. The independent variable in this lab would be the temperature.

The goal of the experiment is to determine the molar mass of an unknown liquid using the Ideal Gas Law and once it is found the empirical and molecular formula could be determine. The theory behind this experiment is the idea that if the pressure, volume, number of moles and temperature are all constant we could easily use the Ideal gas law equation to find the molar mass of a gas. obtain this information we would need to heat up and unknown liquid in a closed flask in boiling water and once the liquid has evaporated the volume and mass is calculated. The values obtained once completing this experiment is 103 g/mol as the molar mass and CH2 for the empirical formula and C7H14 for the molecular formula.

CO2 solubility in PSU CO2 solubility in PSU increases with a decreasing foaming temperature. PSU samples were foamed in a temperature range of -10 to 600C.

A safety audit for the gas-solid fluidization experiment was conducted. The following safety concerns were found when performing the audit: operating beyond the operational limits, spillage of the beads, risk of head injury from bending over to change the beads in the apparatus or from the low bar, and congestion of the workspace. One of the biggest safety concerns with this lab involved the small glass beads that acted as the solid in the experiment. If the gas flow rate goes below 50 standard cubic feet per hour (SCFH), the small glass beads could enter the flow meters.

A dry gas meter (Harvard, UK) was used to measure the volume and temperature of the gas, and a gas analyser (5200, Servomex, UK) was used to determine O2 and CO2 levels. The timing in this study was determined with a Stopwatch (DT100, Digi Lap,
