The goal of this experiment was to use chemistry to analyze an unknown compound and through testing its physical and chemical properties determine what unknown compound that was found in a landfill. This would benefit the Environmental Protection Agency because once they know what the substance was they could determine the best way to remove it from the landfill and if there were any potential safety hazards to beware of while handling the substance. This would prevent any accidents that may…

Hobbytown Rocket V.S. Chemistry Rocket Research Paper A Rocket is a projectile that can operate on it's own without oxygen by the combustion of it's contents. Rockets are particularly interesting because it has transported mankind where they have never been before. That is why this project is on Rocketry, but with small scale rockets. The purpose of this project is to see if a homemade Chemistry Rocket, fuel made of baking soda and vinegar, can equal the endurance and/or the height of a…

In this lab, two methods of distillation (simple and fractional) were utilized to separate a mixture of volatile compounds (cyclohexane and toluene). As a first observation of the results and data generated, looking specifically at the simple and fractional distillation curves, it seemed that the fractional curve obtained was not as expected. In fact, it was not very different from the simple distillation curve, having a gradual positive slope. This means that there was actually not a big…

The objective goal of this experiment is to identify a set of unknown liquids by measuring the liquids of three physical properties which consists of determining the density, solubility and boiling point of the liquids A, B, C and D. Ethyl acetate, methanol cyclohexane and acetone were the unlabeled liquids. In the data analysis the predictions came out to be liquid A for acetone, liquid B is for ethyl acetate, liquid C is methanol and liquid D is cyclohexane. Introduction and Experimental…

Maciej Szwoch Chm 131-005 5/5/18 Writing Assignment Figure 1 [This diagram shows at what temperatures/pressures water changes phases. As shown in Figure 1 (“Interactive Student Tutorial”) above water turns into a gas at 100 degrees Celsius. At 0 degrees Celsius and below it becomes a solid. This diagram makes it easy to see that the energy needed (temperature) to change phases greatly increases] Molality Molality is the number of Moles of solute divided by kilograms of solvent (Tutapoint…

far less than regular gas powered vehicles. An aggressive boost in hybrid vehicles would reduce the levels of Co2, slowing climate change in the process. Nonetheless, a vast majority of Americans still drive gas powered vehicles regardless of their views on climate change. Factors that influence hybrid vehicle sales the most, besides climate change, in the United States are political parties, government, and money. So why are the numbers still so low compared to regular gas powered vehicles? Do…

meter circuits * Moving coil ratiometers * Moving magnet ratiometers THERMOCOUPLE INSTRUMENTS – do not require any external power since a thermocouple is an electrical generator. CYLINDER HEAD TEMP. (CHT) – For reciprocating engines. EXHAUST GAS TEMP. (EGT) – For both reciprocating and turbine engines CONSTANTAN – a copper nickel alloy used as the negative lead of a thermocouple for measuring the CHT of a reciprocating. CHROMEL – an alloy of nickel and chromium used as the positive…

plasmas) move faster, they carry more kinetic energy and feel warmer than a material with slower particles. Boiling Boiling is the process where molecules transition from the liquid phase to the gas phase, resulting in the formation of vapour bubbles within the liquid (Figure 1). Figure 1 – Liquid changing to a gas. Boiling Point Boiling point is the temperature at which the vapour pressure of the liquid equals the environmental pressure that surrounds the liquid. At boiling point, the vapour…

Paintball is a game that shoots out markers or paintballs, that when they hit, the markers explode causing a paint mark on a person, a piece of cover, and trees.Paintball is also a game where many people do different types of games like capture the flag to different battle scenarios. Before paintball was a game paintballs was used to mark cattle for shipping purposes. Many people play this game with pump guns. These guns have an air pump attached and also a hopper.The hopper is the top piece of…

The results from the experiment generally show the trials with full light intensity to have produced more oxygen, showing the elodea samples to have photosynthesised more than the lower light intensity trials. Trials 1 and 2 were in water bath 1 with full light intensity, whereas Trials 3 and 4 were in water bath 2, with lower light intensity. Experimental error caused the trials with the lower light intensity to be disrupted, and no data was collected for these trials on Day 8 of the experiment…
