On September 8‚ 2016‚ I agreed to drink 64 ounces of water to maintain a healthy hydration level. When making a list of obstacles I failed to account for the stress and work at school. I think writing obstacles and ways to overcome them was beneficial. By having a set plan as to how to overcome obstacles I felt I had no reason to procrastinate or not do what I planned. Calling my own self out is just the wakeup call I need to stay hydrated and complete my goals. Completing and creating goals on the

with its surroundings. In combination with entropy determinations‚ it is used to predict whether a reaction is spontaneous or non-spontaneous‚ favourable or unfavourable. Chemical reactions can be divided into two based on the energy changes that occur during the reaction which are endothermic and exothermic reactions. Endothermic reaction is a chemical reaction that absorbs heat energy from the surrounding. Hence‚ it has a positive value for enthalpy change of reaction. In contrary‚ exothermic reaction

The Copper A. In the text “the Copper” Glenn Gavin tells about his experience and viewpoints 20 months after he joined the Metropolitan Police. In the text are different subjects discussed. Glenn Gavin talks about his upraise inside the family and at school‚ the role of rules‚ his choice of carrier‚ and attitude toward politics. When Gavin was a kid his parents gave him a “guiding kick up the backside every now and then” (p. 1 l. 2). For example when he “came in late” (p. 1 l.3) or if he “was

Determining an enthalpy change of a displacement reaction Aim: To determine the enthalpy change for the displacement reaction between zinc powder and copper (II) sulphate solution. Zn (s) + Cu2+ (aq) → Cu2+ (s) + Zn2+ (aq) Theory: For the displacement reaction‚ an excess amount of zinc powder is added to the measured amount of aqueous copper (II) sulphate. The temperature change over a period of time has to be measured and thus‚ the enthalpy change for the reaction can be measured. The equation

There are four major factors that often contribute to the formation of hydrothermal copper porphyry: 1) readily available mineralizing fluid solutions that dissolve and transport metals‚ 2) openings in rocks which allow permeable flow of hydrothermal fluids and the metals that they transport in solution‚ 3) available sites within the fractured rocks which allow for deposition of the minerals from solution‚ and 4) the requisite chemical reactions that contribute to that deposition (Bateman‚ 1967)

EXPERIMENT 8 QUANTITATIVE DETERMINATION IODOMETRIC TITRATION OF COPPER CONCENTRATION IN AQUEOUS SOLUTION B Y RESULTS AND DISCUSSION Considered as moderately weak oxidizing agent‚ Iodine was used for the determination of strong reductants. Standard iodine solutions were found to have smaller electrode potentials as compared with the other oxidants‚ gaining them the advantage of imparting a degree of selectivity essential in the determination of strong reducing agents amid the presence

Determining the enthalpy of neutralization by calorimetry Anam Iqbal Partner’s name: Danielle Hodgson TA’s name: Karinna Section # 003 Due date: November 24‚ 2009 Introduction The purpose of the experiment is to determine the enthalpy of neutralization reactions by calorimetry. Calorimetry‚ is the science of measuring the amount of heat. All calorimetric techniques are therefore based on the measurement of heat that may be generated (exothermic process) or consumed (endothermic process). The

This lab is performed in order to determine the total energy in a reaction between zinc and hydrochloric acid. The reaction is done twice‚ once to measure the heat of the reaction and again to determine the work done in the system. This is because Enthalpy equals heat plus work (∆H= ∆E+W). Heat and work can be broken down further into separate components so the equation used in lab is ∆H=mc∆T + PV. Many calculations are used in the lab to find out what cannot be measured directly (ex: volume). After

Good hydration is important for athletes as their body lose water through sweat to keep it cool down. Control levels of fluid and water balance even before‚ during and after training or during matches are essential aspects for the athletes. For low intensity exercise lasting for a short duration such as low intensity training or during rest between each training session‚ water is very good for rehydration (Nutrition Australia‚ 2009). In addition‚ high intensity and endurance sports last longer than
