Hypovolemic shock is the result of severe blood/fluid loss causing the heart to inadequately circulate oxygen to the rest of the body (Workman, 2013, pp. 812). In this condition, there is sudden decrease in blood volume within the vascular space causing a drop in mean arterial pressure. This decrease in mean arterial pressure causes a sudden loss in the oxygen carrying capacity of the blood related to the sudden decline in available red blood cells. As the heart is unable to properly pump oxygen…

Renin secretion is stimulated by decreased blood volume, decreased renal perfusion, sodium and water depletion. Subsequently, renin promotes the conversion of angiotensinogen to angiotensin I. Angiotensin I is then converted to angiotensin II through the angiotensin converting enzyme. Due to angiotensin…

Costco Wholesale Corporation, which operates as a membership retailer, which specializes in selling quality products at low prices was founded in 1983 by James Senegal and Jeffery Brotman, with both having a background in retailing and established the first warehouse in Seattle, Washington. In 1993, there was a merge between Costco and Price club forming Price Costco causing a double in size in comparison with the parent company, and in 2007 the corporation became the seventh largest global…

powder behavior in compaction. It was initially used to study the densification of ceramics and its correlation with pressure. It a first order process where powder pores elimination rate is correlated to the number of pores present. The rate of volume reduction increases as the number of pores decrease. Heckel equation relates the density, pressure and the pore fraction of the powder [16],. This was expressed mathematically as: If the compaction is achieved by plastic deformation and there…

liquid after it refluxed for 50 minutes. In addition, the reaction had a slightly odor to the bananas. Once the vial was cooled to room temperature, the vial was placed in an ice bath for 3 minutes. After, 1.0mL of ether was added to the vial and the volume was adjusted to…

gas will not affect the system. First of all, argon is an inert gas, which means it will not react with anything involved in this reaction. Since it does not react, it cannot affect the equilibrium constant. Increasing the pressure by decreasing the volume of the container will change the system by causing more solid CaCO3 to form. In order for the system to counteract the change of pressure, it needs to remove moles of gas from the system, according to PV=nRT. This is achieved by forming more…

completely dissolved. Titrate with standard base 0.1N NaOH, shake vigorously until the endpoint is reached. This is indicated by a slight pink color that persists for 30 seconds. Record the volume of the titrant used. Finally, repeat the steps more carefully in triplicate, recording each weight of the sample and the volume of the…

The initial volume of NaOH in the buret was collected. Next, the oxalic acid solution was created. An analytical balance is used to measure the amount of oxalic acid. The small plastic weigh dish was placed on the balance and the tare button was pushed in order to…

DETERMINATION OF pKa AND pKb USING ACID-BASE TITRATIONS Introduction Acid-base titrations can be used to determine pKa of a weak acid and pKb of a base. A weak acid and a weak base incompletely dissociate in water. For this reason, the concentration of hydrogen ions (H+) and hydroxide ions (OH-) depend on equilibrium coefficients of acid (Ka) and base (Kb). Equation 1 shows the chemical dissociation equation of a weak acid. Furthermore, Equation 2 describes the equilibrium constant of a weak…
