The objective of this experiment was to learn the process of recrystallization and how this process removes the impurities from a pure solid compound. The methods used to achieve this objective were also hot vacuum filtration in order to remove suspended solid impurities‚ and isolating the pure acetanilide. In the next lab‚ percent recovered was obtained through weighing the acetanilide sample as well as comparing its melting point range. In this experiment‚ the sample‚ acetanilide was weighted

weren’t for the spacewalkers‚ memory foam would not have existed. Vacuums also were invented by astronauts. They wanted to create a drill that would be able to extract core samples from below the lunar surface. “Black & Decker was tasked with the job‚ and developed a computer program to optimize the design of the drill’s motor and insure minimal power consumption. That computer program led to the development of a cordless miniature vacuum cleaner called the Dustbuster”(Spinoff 1981). They wanted to create

Purpose: The Purpose of this lab is to utilize‚ demonstrate and understand the various techniques and procedures used to gravimetric labs. For this particular lab we will utilize our scientific knowledge of related to gravimetric procedures to find the chloride content in an unknown soluble salt. Theory: Using our developed knowledge of the conservation of mass‚ solubility and precipitation it is possible (with some degree of error) to know the content of chlorine in a particular salt by dissolving

several factors affected the signals. For instance‚ the vacuum‚ which directly affect the pressure‚ and also the Width‚ which control the amount of gases put into the chamber. By adjusting them‚ we looked for the better signals. Discussion: The experimentation process was profitable‚ but the outcome was not as desirable as we expected. Therefore‚ we need to make some improvement in the future research. In the future‚ we are going to improve the vacuum condition. (Current pressure of CP-FTMW spectrometer

Activated Sludge Process will encompass * Design of aeration basins. Relevant design parameters are * BOD load from the upstream process * Mixed Liquor Suspended Solids Concentration (MLSS – mg/l) – typically 2‚000 to 4‚000 * Sludge Age 5 to 25 days * Sludge settleabiltiy (SVI ml/g) typically 100-120 * Process Oxygen Demand (POD) * Generally fine bubble diffusers used in modern plant design – actual oxygen transfer efficiency dependent

Synthesis of Aspirin and Tylenol Kyla Wykoff Abstract Aspirin and Tylenol were synthesized by means of crystallization‚ recrystallization‚ and melting point determination. Synthesis produced significantly high percent yields for aspirin‚ however‚ produced extremely low and impure percent yields for Tylenol. A second group was also used to compare results and errors‚ in which they too were also producing extremely low percent yields of Tylenol. Therefore‚ error was based on the specific protocol

Primary properties of visible light are intensity‚ propagation direction‚ frequency or wavelength spectrum‚ and polarisation‚ while its speed in a vacuum‚ 299‚792‚458 meters per second‚ is one of the fundamental constants of nature. Visible light‚ as with all types of electromagnetic radiation (EMR)‚ is experimentally found to always move at this speed in vacuum. In common with all types of EMR‚ visible light is emitted and absorbed in tiny "packets" called photons‚ and exhibits properties of both waves

Why is it ethical to eat meat? The answer is ridiculously simple: Because we do not live in a vacuum. Man isn’t the only creature on the planet that eats meat. From single-celled organisms to polar bears‚ in every environment from the deepest ocean trench to the highest mountain peaks‚ carnivores abound. So if Nature herself sees nothing "unethical" about creating scores of living beings that feast on meat‚ what makes humans think we know better? And were does this belief that meat-eating must be

How Can I Save Energy At Home? There are many ways to save energy at home‚ some of these examples are: 1. Solar panels - Most modern homes are built with solar panels‚ and a lot of the older houses are now installing them. Solar panels are a great way to save energy because they create energy from the sun and lower your electricity bill saving you money. 2. Using gas instead of electrical appliances when cooking at home - When cooking with gas you have more control over the temperature
