Observations and Chemical Changes By: Andre the Giant Higgson 02/19/14 CHE 107 E1 Intro to Chemistry 1 Objective Certain Chemicals like Bromthymol blue and Phenolphthalein can be added to other chemicals to determine acidity or basicity. Other reactions can be observed as well when different chemicals are added to each other. Procedure This experiment involved placing drops of specified chemicals into a well on a 96well plate. Each well number was recorded along with question number and name of chemicals involved

Solid waste management Introduction to solid waste management Solid waste is the unwanted or useless solid materials generated from combined residential‚ industrial and commercial activities in a given area. It may be categorised according to its origin (domestic‚ industrial‚ commercial‚ construction or institutional); according to its contents (organic material‚ glass‚ metal‚ plastic paper etc); or according to hazard potential (toxic‚ non-toxin‚ flammable‚ radioactive‚ infectious etc). Management

TITLE Vapour Liquid Equilibrium OBJECTIVE To find the Vapour-Liquid Equilibrium (VLE) relationship for binary mixture and to plot the equilibrium curve. INTRODUCTION The term equilibrium is referred to as when a system is in a static condition and there is absolutely no changes that occur as time goes by. Vapour-liquid equilibrium is a condition where a liquid and its vapor are in equilibrium with each other‚ a condition or state where the rate of evaporation is equal to the rate of condensation

Solid Waste Management Sci/275 Shannon Johnson 08/21/10 Shannon Gumtau The terrestrial resource I chose was solid waste. The EPA defines solid waste as “any garbage or refuse‚ sludge from a wastewater treatment plant‚ water supply treatment plant‚ or air pollution control facility and other discarded material‚ including solid‚ liquid‚ semi-solid‚ or contained gaseous material resulting from industrial‚ commercial‚ mining‚ and agricultural operations‚ and from community activities. What this basically

Liquid crystal display Reflective twisted nematic liquid crystal display. 1. Polarizing filter film with a vertical axis to polarize light as it enters. 2. Glass substrate with ITO electrodes. The shapes of these electrodes will determine the shapes that will appear when the LCD is turned ON. Vertical ridges etched on the surface are smooth. 3. Twisted nematic liquid crystal. 4. Glass substrate with common electrode film (ITO) with horizontal ridges to line up with the horizontal

How a Bill Becomes a Law. To make a bill into a law is written out for us in the Constitution. However the Constitution only gives you an idea of how to make a bill into a law. It gives you a broad perspective of how to approve a bill and what to do for approval. Most of all the all bills are looked at on a subjective form‚ thus meaning that whoever creates the bill‚ approves it and or veto’s it‚ is all on a someone’s opinion. To give you a short brief idea of how a bill is processed it must

Liquid Film Motors [pic] Fiona McLaughlin Zoe Cheng Loreto College Coleraine Comments Abstract We have carried out an experimental and theoretical study of liquid film motors. This phenomenon was first reported in 2009. Two papers have been published on arXiv.com‚ the first describing the phenomenon (Shiryaeva et al)‚ the second offering a theoretical model for the observations (Amjadi et al). The

Labset Five Worksheet 1. List five environments where you are likely to find microbial growth: Lakes‚ soil‚ oceans‚ tundras‚ deserts 2. How do microbes contribute to soil fertility? The decomposition that microbes take part in help release mineral nutrients‚ such as potassium and nitrogen‚ from dead organic matter and allowing primary producers the nutritional access. They also produce CO2 and CH4 to release into the soil and atmosphere. 3. Describe the growth you observed in each of your

Observations of Chemical Changes Purpose/Hypothesis: To observe how acids react with bases and examine reactions of common household cleaners and the macroscopic changes these chemicals undergo. I expect for each solution to react differently when mixed with acids and bases. Procedure: I have a well-plate-96‚ a piece of white and black paper‚ and the chemicals from the Observation of Chemical Changes Experiment Bag. I used a different well for each combination of solutions. I placed two
