    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 Details: In order to determine the density of the liquid, the…

    Crystals form when a type of liquid cools down, and then hardens. The process when crystals grow is called "nucleation". Whenever a person eats salt, they are eating salt crystals. These crystals are called salt crystals. To make homemade salt crystals, the materials you need are hot water and salt. When dissolving salt in water, the salt is not changing its properties. This project will use different types of waters to see how many more crystals it will help grow. Dasani water is a brand of…

    In order to illustrate how fracking works, jets shoot fracking fluid, which is a mixture of sand, water, and hundreds of chemicals, into the drilled hole to create cracks in the shale. The fracking fluid breaks down the shale releasing the oil, which gets pumped back up to be treated. Most of the fracking chemicals are undisclosed by fracking companies and could be potentially harmful; can be performed in a vertical oil well, as well as into shale and tar sands (Walsh). When mining deeper oil…

    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…

    Identification of Unknown Compounds 64A and 64B 64A, was a white powdery solid substance. 64B, was a clear colorless liquid that had the smell of alcohol. Solubility analysis is a method of identifying compounds based on how their behavior in other compounds. Solubility is the ability of a solvent to dissolve a solute. For a solvent to dissolve a solute, it has to be able to break the intramolecular forces of the solute. The intermolecular forces between the solvent and the solute have to be…

    Aim - To investigate how the temperature of water affects how salt dissolves. Prediction - If the temperature is warmer, the more solute will dissolve in the solude. Variables - which variables are you going to: Independent Variable - The temperature of the water. Dependent variable - How much salt is needed to not dissolve in water. Controlled variables - The materials. How will you make it a fair test? - Using a machine to weight the salt and heat the water.…

    Standard solution is the solution that is been made by dissolving a precise mass of reactant meaning the starting substance in a chemical reaction, and it is important that the mass is weighed accurately into distinguish volume of water that will be used. This tells us that if the concentration of standard solution is accurate then it can also be used to work the concentration of a different solution that it can also react with. Its concentration is generally given in mol dm-3. Standard solution…

    Fracking: A Controversial Topic If someone offered you $100,000 to drill on your land, would you accept the offer? Would the $100,000 be worth the sacrifices? Fracking, or hydraulic fracturing, is the process in which chemicals and liquids are injected into rocks below the Earth’s surface at high pressure to extract the natural gas or oil trapped inside the rock. Below the surface of the United States lies trillions of cubic feet of natural gas, a quantity which is twice the amount of oil in…

    • 6 Pages

    When confronted with an obstacle, the easiest and the most efficient way to achieve a resolution is always the most desired; however, when assessing the act of fracking, it may be one hole that should not be drilled. Fracking is the process of using hydraulic machinery to access oil and gas in areas of the Earth’s crust that are otherwise hard to retrieve. Where there are some benefits to using this system, the consequences of fracking are far more catastrophic to our environment. Ethically,…
