Ideal gas

This reaction involves very intricate and steps that are critical to understanding the concept of equilibrium as a whole. First, an important concept to understand when describing any reaction is the idea of collision probability. When we examine gas molecules in a 1 cm3 container, there can be billions of collisions per second between neighboring molecules, and even then, maybe only one of these collisions result in a reaction. If any one collision occurs, the only way they will react to form a…

Ultrasonic interferometer Working principle An ultrasonic interferometer is a simple and direct device to determine the ultrasonic velocity in liquids with a high degree of accuracy. An ultrasonic interferometer is used to determine the accurate ultrasonic velocity in liquids. The principle used in the measurement of velocity is based on the accurate determination of the wavelength in the medium. The principle of ultrasonic interferometer for the measurement of velocity is determination of the…

When dry ice is put into water they start to reacting and boiling. That reaction is called sublimation. Sublimation is when something solid goes straight to gas skipping the liquid phase. So because the water is warm it heats up the dry ice which causes it to form a gas. The gas is carbon dioxide. The temperatures of everything are very strange. The water cannot be cold when trying the experiment because it will not heat up the dry ice and create carbon dioxide gasses but it will probably…

A filter is something that removes impurities or solid particles from a liquid or gas that passes through it. There has been a total of 76% of deaths due to infections from dirty liquids and poisonous gases. Not many filters do the same job you would like it to do, but with this particular filter it is made to filter out gases, liquids, and solids from a variety of different elements and objects as well as cleaning any object you toss into it. The item's frame is powerful enough to do these…

A mixture of two unknown liquids were obtained. The assigned mixture code was recorded in the notebook (#10). The mixture of the two miscible liquids contained a low boiling point and high boiling point. The method used to separate the two miscible liquids was simple distillation and therefore a simple distillation apparatus was set up. The apparatus included 250mL distillation flask, a 100ml receiving flask, a condenser for water to run through, and a thermometer to monitor the temperature. The…

IB Standard Level Environmental Systems and Societies Internal Assessment The Effect of Varying Amounts of Yeast on CO2 levels IA1 Isobel Woodfin Third Period October 14th, 2015 Paul Ogle-Sporer, Davis O’Shea SECTION 1: PLANNING Research Question: This lab was designed in order to answer the question: How do increased/varying amounts of yeast affect the CO2 levels of decomposing apple? Introduction: This experiment tests the effect of varying amounts of…

Introduction/Purpose: Chemicals all perform different reactions when dissolving into different chemicals, and in the lab “Our First Lab” my group and I observed one of these chemical reactions. The purpose of the lab was to witness the chemistry behind these reactions in action, so we could put research and observations together on how it was possible for something to illuminate with only a forced bend to it. Observed how each light sticks glow depended on the temperature they were exposed to,…

According to the data table, the resilience of observation #2 is greater than observation #1 because the more borax solution in the slime, the more viscosity it has. By Newton’s discovery, the greater the viscosity, the harder and solidified the slime will be which all the bonds between the white glue and borate ions are tightly hold together. Base on the data provided above, the slime in observation#1 can be stretched longer than the slime in observation #2 because the #1 slime has less borax…

Anhydrous ammonia is the target of methamphetamine (meth) producers after it spilled out the derailed train cars 10 days ago in Stoughton. Anhydrous ammonia is a key ingredient in the production of meth, the highly addictive, central nervous system stimulating drug. Meth has a high potential for abuse and dependence, and is very easy to make when utilizing anhydrous ammonia. Two tankers that remain at the crash site still have anhydrous ammonia inside of them. These tankers are now under…

The solvent systems separated fluorene and 9-fluorenone based on their difference in structure and polarity. The petroleum ether solvent system was helpful in washing away anything that was hydrophobic since it’s nonpolar, and it essentially washed off most of the fluorene since fluorene is not as polar as 9-fluorenone. The solvent system with a mixture between Dichloromethane and petroleum ether allowed the yellow band to be eluted off the column because polar solvents such as Dichloromethane…
