(a) Define the term equilibrium potential and use the Nernst equation (see Appendix) to show how the equilibrium potentials for both sodium and potassium are calculated. Equilibrium potential is the potential of the membrane when there is no net flow of ions from one gradient to the other gradient. The ions are equal and are opposite of each other but not moving from one side to the other. Sodium: Ena=2.303((8.31 J m-1 K-1)(310K))/((1(= 9.65 x 104 c m-1))(log(150/15))= 61.54 mV Ek=2.303((8

International trade friction in the new situation and the situation was still rubbing Suggestions increased [Abstract] With the growth of international trade‚ trade friction between countries than in the past increased significantly and has shown new features and new situation. In the face of the increasingly frequent and complex trade friction‚ this paper presents 15 new countermeasures for industry colleagues to explore.

With Static Modelling as the name indicates it is a ridged fixed model and does not change with the any introduction of outside forces. i.e. Building plans on a house‚ the plans represent a model of a house‚ without any introduce of how safe the land is whether

Homeostasis is a state of equilibrium that tends to be a main goal in many scenarios in living organisms‚ including those within the body. One of which includes the human body temperature which usually is around approximately thirty-seven degrees celsius or ninety-eight and six tenths degrees fahrenheit. This temperature is ideal for the human body because at this temperature it is not too warm as to where the body would have to continually eat and take in nutrients in order to maintain it’s metabolism

SPECTROPHOTOMETRIC DETERMINATION OF EQUILIBRIUM CONSTANT OF A REACTION UNIVERSITY OF THE PHILIPPINES‚ DILIMAN QUEZON CITY‚ PHILIPPINES August 2‚ 2013 ABSTRACT The objective of this experiment is to determine the equilibrium constant‚ denoted Keq‚ for the formation of [Fe(SCN)]2+ complex which is a product of the reaction between the ions Fe3+ and SCN-. In performing this experiment‚ solutions containing FeCl3 and KSCN‚ diluted in HCl‚ were measured for their absorbance using a UV-Vis

The expected heterozygosity (He)‚ in average‚ was higher than the mean observed heterozygosity (Ho) for ‘Big Sister’ populations‚ and Ho higher than He for ‘Enfant Terrible’ (Table 3). Departure from Hardy–Weinberg Equilibrium were significant at a 5% level (P<0.001) for only 3 populations (BANA‚ CAMP and ITAR). Based on the estimates of the inbreeding coefficient over all loci‚ the significant deviations were due to an excess of heterozygotes (negative GIS = more observed

Our inspiration for this experiment came from a lecture in class about the Los Angeles council agreeing that there should be a law limiting homeless people’s belongings to what can fit in a trash bin. This would force the homeless people to throw away large portions of their belongings to benefit the city from not having “trash” on the streets. According to the L.A. times‚ the legislation California believes that this law will “limit storage on sidewalks‚ parkways‚ and alleys citywide to what homeless

Chemical Equilibrium: Le Châtelier’s Principle Abstract This experiment entitled "Chemical Equilibrium" aims to help students to investigate the effects of concentration and temperature upon the position of equilibrium in a cobalt chloride solution‚ Co(H2O)62+. In this experiment‚ cobalt crystal is dissolved with distilled water and ethanol which the initial colour is purple-pinkish and a few drops of concentration of HCl is added to the test tube‚ the final colour is in deep blue colour.
