10th grade I have many career goals I want to achieve. One of my top career goals is to become a nurse and be able to work in that particular field in the army. I know I would have to do well in college and learn the techniques in order for me to become a nurse. I decided to pursue this specific career field because not only will it help me, but it will help others. People get sick and hurt every day, I would love to be that person to make them feel better and put a beautiful smile on their face. I actually love making people happy and laugh. In order for me to reach my careers goals I will use all the strength and knowledge I know. I will use the strength of my family, because they support me at everything I do. One of my most powerful strength is to silence all the negative voices in my head, and I would most definitely use that one at all times. Working in this particular field will benefit society because families send their loved ones to go fight for our country, each family expect for their loved ones to return back home healthy as ever. If it wasn’t for nurses or caregivers working in the army, how would the soldiers survive? I wish to participate in the 2014 shadow and executive program because it will actually give me many opportunities; such as taking the ACT for free offering to let me spend time with professionals at their work place. This program will show me all the steps I need to take in order for me to get to
Fractional Crystallization Suggested Reading 8.1-8.3 Introduction A solution is a homogeneous mixture of at least two components. Homogeneous means only one phase/state is visible. For example sugar water; you only see one liquid phase when looking at the glass even though both sugar and water molecules are present. Sugar water is a solution of two components, sugar which is termed the solute and water which is the solvent. The solute is the component present in a lesser amount…
COMPOUNDS AND MIXTURES In this unit you will learn to .. distinguish between elements and compounds and how they are represented by symbols and formulae - these show the relative numbers and types of atom present recognise chemical change as a process in which atoms join together in new ways distinguish between compounds and mixtures distinguish between chemical reactions in which new compounds are formed and the formation of mixtures investigate temperature changes as liquids cool use line…
In general the boiling point of a molecule increases as the length of the carbon chain increases, this is due to the fact that there are now more atoms within the molecule and therefore more intermolecular forces to be overcome (Unknown: 2014). Intermolecular forces are forces that act between atoms in a molecule or molecules themselves (Hydrocarbon boiling points: 2014). The more carbon atoms the heavier the entire molecule becomes, this means that more energy is required to make the phase change…
atoms of two or more elements are combined in a fixed proportion I. Mixtures II. A mixture is a material made up of two or more substances that can be easily separated by physical means a. Heterogeneous Mixtures i. A mixture in which different materials can be distinguished easily is called a heterogeneous mixture. ii. You might not be able to spot these mixtures with the naked eye. iii. Some components are easy to…
The Equilibrium Constant of an Ester Hydrolysis Reaction CHM 152 Shaina Moon Lucas Bodine Professer James Giles 10/29/2014 Abstract: A series of five reaction mixtures were prepared and titrated to a pale pink endpoint using a standardized NaOH solution in order to find the equilibrium constant. The average equilibrium constant was calculated to be Kc=0.157. Introduction: The purpose of this experiment was to determine the equilibrium constant (Kc), for the acid-catalyzed reaction between an…
Q: What is a solution? A: A solution is a homogeneous mixture of one or more solutes dissolved in a solvent. Ex. table salt dissolved in water B) Q: What is a pure substance? A: A pure substance is something that cannot be separated and is made of allof the same particles Ex. Water (H2o) is a pure substance C) Q: What is a mixture? A: A mixture is a substance made by combining two or more different material .Ex. Salt Water= Salt, Water d) Q: What is a homogeneous mixture? A: A homogeneous…
Separation of A Mixture of Solids Objectives: To become familiar with the separation of mixtures of solids. Procedure 1. Separating out the Iron a. Use your digital scale to determine the mass of your weighing dish. Scale is at zero before weighing. Weighing dish is weighed. b. Empty the entire mixture of solids from the plastic bag into the weighing dish and determine the gross mass of the total mixture and weighing dish. Compute the net mass of the mixture: this is equal to the gross mass…
, 2000) Purpose: To observe what happens when two aqueous solutions of ionic substances react and linking the observations of the reactions with the solubility rules. Hypothesis: My prediction is that the reactions of the two aqueous solutions of ionic substances will follow the solubility rules positively. Materials: Laminated Drop Sheet Data Table Pencil Container of Ionic Substances Toothpicks Safety Note: Since many of these solutions are moderately toxic by ingestion, wash your hands thoroughly…
components are in a mixture and therefor it may help him identify the nature of the mixture. In fact TLC is used to separate mixtures of substances into their different components. Chromatography works this way: there is a stationary phase, the silica gel (the stationary phase also contains a substance which fluoresces) and a mobile phase, which is a suitable solvent. The mobile phase is a solvent flowing through the stationary phase while carrying the different components of the mixture studied. The different…
methods used to separate a miscible mixture (a solution) of volatile liquids which have different boiling points is termed DISTILLATION. Distillation involves boiling the volatile mixture and condensing the vapors produced. Simple distillation can effectively separate liquids whose boiling points differ by 80 degrees or more, while Fractional distillation can be adapted to separate liquids whose boiling point difference may be as small as 0.10°C. When a solution is composed of two or more volatile…
