The second one is utilizing 65 Zn to analysis the removal of zinc in two different types of environment, mangrove-vegetated forest, and unvegetated tidal creek. In this study, sediments from a mangrove ecosystem in Sepetiba Bay was utilized for investigation since Zinc is the major contaminant in this region. In the laboratory, researchers used radiotracer 65Zn with half-life 244 days to undergo the experiment. Among the isotope of zinc, 65Zn has the longest half-life. Since it is the first time…

A water table marks the top of the saturated zone of groundwater. When something is saturated, it means one substance (Like soil) is filled with another substance (Like water). Therefore, the area filled with water is called the saturated zone. This zone can be called the phreatic zone or the zone of saturation. This is always the zone below the water table. Directly above a water table there is always a capillary fringe. The water table separates the capillary fringe from the zone of saturation…

Once inside of the large bathroom, Jimin turns the tub on and waits until it's at a good temperature and doesn't scorch the hybrids skin, then lets it run until it's halfway filled. He turns to Jungkook, "Do you want me to leave while you wash up?" Jungkook's eyes widen, "No no! Don't leave," then he quiets down as a blush covers his cheeks, "M-Master always cleaned me. I don't like cleaning myself." A nod comes from Jimin's end, "Well then let's get you out of these gross clothes, okay…

Solubility Curves Lab Report Objective: To demonstrate how the solubility of a salt varies with temperature and plot the solubility curve of a salt on the basis of observed data. Introduction: Solubility is the maximum amount of substance that will dissolve at a specific temperature. The units for solubility are grams of solute/ 100 grams of solvent. A solute is the substance being dissolved. A solvent is present in greater amount. The solubility of a solute is defined as the amount 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…

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…

CHAPTER 1: BACKGROUND 1.1 ENHANCED OIL RECOVERY Oil production is differentiated into three stages: primary, secondary and tertiary, which is also known as Enhanced Oil Recovery (EOR). Primary oil recovery is restricted to hydrocarbons that naturally produced to the surface, or those that utilization artificial lifts, for example, pump jacks. The secondary recovery utilizes water and gas injection, dislodging the oil and driving it to the surface. US Department of Energy stated that by using…
