Determining the unknown concentration of HCl via heat of neutralization of a reaction involving strong electrolytes and weak electrolytes. Myeongwon Lee 20522885 Partner: Frank Wong TA: Afsoon CHEM 120L – Earth Science & Chem 149 Section: 004 Tuesday‚ November 26th‚ 2013 Introduction All chemical changes are accompanied by change in energy and this energy is in form of heat. The energy change of a reaction that happens at constant pressure is defined as heat of reaction or enthalpy change and the

‘Enteral nutrition (EN) refers to nutrients given via the gastrointestinal tract’ (GIT) (Crisp and Taylor 2009 pp.1154). EN is considered when an individual is not safe for oral intake or when oral intake is not adequate to meet nutrient requirements‚ for example when a patient is unable to swallow. Enteral feeding tubes may enter the body at a number of different sites‚ the choice of enteral feeding route depends on several factors such as the intended duration of the nutrition support‚ the patients

Throughout time many athletic players drink sport drinks like gatorade or powerade but the question is when should we drink sport drinks or water. Your body needs water to maintain performance. Water is composed of two hydrogen and one oxygen atom. For your body to maintain athletic performance it must have oxygen in the muscles (which water contains). When exercising we burn carbohydrates. When we lose these carbohydrates they need to be replaced. There are many alternatives to replace carbohydrates

used to measure how many electrons flow through the cell and amp is the basic unit for current. There are lots of important parts for regular batteries. They are the positive terminal and electrode‚ the negative terminal and electrode‚ and the electrolyte which is located between the two electrodes. The positive electrode is made out of a carbon rod. Powdered carbon and manganese oxide prevents hydrogen from forming on the carbon rod‚ which would stop the cell from working normally. For the negative

generate electricity through a chemical reaction between two different electrodes and one electrolyte. Use of Copper and Zinc electrodes and Sulfuric acid as electrolyte is a proven method for this process. We are wondering if we can use any other liquid as electrolyte? This gave us the idea of using a potato as electrolyte. After all a fresh potato has a lot of juice that may serve our purpose as electrolyte. Problem: Can Potato be used to generate electricity? Hypothesis: Potato juice

is Ionic‚ it will be an electrolyte‚ because they mostly break up into ions when in water. If the compound is molecular‚ then it will be soluble‚ it cannot be an electrolyte‚ and it can be an acid or base‚ because molecular compounds are soluble in organic solutions such as water‚ they do not have any delocalized electrons‚ and are not able to freely move. If the compound is an acid‚ then it will be both a molecular compound

Polarization is the

Bicarbonate will get rid of the excess hydrogen ions and return his blood to normal. C. Eugene’s vitals are: pulse rate 110/min‚ blood pressure 135/80‚ respirations 25/min‚ and blood oxygen saturation 97%. I know Eugene is an alcoholic and has pancreatis. I also know that there is a problem with his electrolytes. Getting the results
