Writing III – Acid-Base Balance Congestive heart failure (CHF) is caused by the inability of the heart to fill correctly‚ eject blood completely‚ or a combination of the two‚ which results in a decrease in cardiac output. Chronic hypertension (CH) is a constantly elevated blood pressure. Peripheral vascular disease (PVD) causes a restriction in blood circulation due to atherosclerosis‚ fatty deposits on the inner linings of the arteries that cause a blockage of blood flow; arteriosclerosis‚ loss

Eichbauer IB Chemistry II – Period 6 16 February 2015 Investigation of the Effects of Acid Rain Background Information Acid rain is when there is a mix of wet and dry deposited material in the atmosphere that have higher levels of nitric and sulfuring acid. These chemicals formed can be from natural causes‚ like volcanoes and the decay of vegetation‚ or man made causes like fossil fuel combustion. Acid rain can be measured using the pH scale‚ and will always be on the lower end of the spectrum

KINETICS OF THE ACID DECOMPOSITION OF THIOSULFATE Aqueous solutions of thiosulfate‚ S2O32-(aq) are stable if neutral or basic‚ but decompose quickly when the thiosulfate is dissolved in acid according to the equation: Sulfur dioxide is a gas at room temperature‚ but is very soluble in water. Sulfur‚ a water insoluble solid‚ forms a colloidal suspension. As a result‚ the solution first becomes cloudy and then opaque. We can take advantage of the developing opacity of the reaction system to do a

Task 4 – The Maintenance of the Acid – Base balance in the body (D1) pH is measured based on its acidity and alkalinity. There are many substances around the body that have different pH values. A pH of 7 is usually considered neutral‚ neither acid nor alkaline‚ this is the pH of water. In the body the acids and bases need to be in very close balance‚ this is called ‘acid base homeostasis. If it goes off too far in either direction then it could be fatal to the body. For example in the body the blood

Activity 1: 1. Did any solutes move through the 20 MWCO membrane? Why or Why not? 2. Did Na+Cl- move through the 50 MWCO membrane? Activity 2: 1. Are the solutes moving with or against their concentration gradient in facilitated diffusion? 2. What happened to the rate of facilitated diffusion when the number of carrier proteins was increased? 3. In the simulation you added Na+Cl- to test its effect on glucose diffusion. Explain why there was no effect. Activity 3: 1. Which membrane resulted

Sugar Metabolism Title: The effectiveness of glucose and fructose metabolism in individuals of resting and exercising observed through blood glucose concentration. Aim: To study the mechanisms of the body involved in absorbing and metabolizing sugar in the form of glucose and fructose and examine the effect of exercise on the rate of removal of glucose from the bloodstream. Introduction: The blood glucose concentration in the blood is interceded by the human body via negative feedback mechanism

Carboxylic acids are compounds which contain a carboxyl group‚ -COOH group‚ where the -COOH group is attached either to a hydrogen atom or to an alkyl group. One of the example of carboxylic acid is benzoic acid( benzene carboxylic acid) which has a benzene connected to the carboxyl carboxyl group‚ -COOH group. It has a formula of C6H5COOH. The carbon atom of a carboxyl group has a high oxidation state. Therefore‚ that many of the chemical reactions used for their preparation are oxidations. In
