Graph 1‚ illustrates the pH of each quadrat. The pH in Quadrat 1 was more acidic than the pH in Quadrat 2‚ 3‚ and 4 this is due to the slope of the ground (refer to Graph 8)‚ different soil substrate and the decomposition of organic matter. As can be seen from Graph 8‚ the soil pH increased with a decrease in the slope of the ground. In Quadrat 1‚ the soil had a pH of 7.5 due to having a higher soil elevation of -8° in comparison to Quadrat 2‚ 3 and 4‚ in which the slope of the ground was -2°‚ -2°

is greater than clearance and lactic acid accumulates in the muscle tissue and can spill over into the bloodstream. This causes blood pH to increase and thus the blood acidity levels rise. Lactate is only harmful to exercise performance with the dissociation of the hydrogen ions from lactate causing the changes in pH levels. This shift in pH is thought to be a significant contributor to fatigue during exercise performance in many ways: (1) by inhibiting phosphofrucktokinase‚ and enzyme important for

THEORIES OF UNIMOLECULAR REACTION RATES 1. LINDEMANN / LINDEMANN-HINSHELWOOD THEORY This is the simplest theory of unimolecular reaction rates‚ and was the first to successfully explain the observed first-order kinetics of many unimolecular reactions. The proposed mechanism actually consists of a second-order bimolecular collisional activation step‚ followed by a rate-determining unimolecular step. k1 A + M Ë A* + M k-1 k2 A* → P Applying the steady-state approximation to the concentration of A*

The Increasing Enthalpy of Combustion Rates for Pentanol Isomers EEI Report Draft - JEREMY SAJU 11B Fuels are the main energy source of the modern world. The topic of this extended experimental investigation is to explore combustion rates of alcohols‚ specifically pentanol and it’s relationship with varying structural isomers. A fuel is defined as a material that stores potential energy that‚ when released‚ can be used as heat energy (Chemguide‚ 2003). The balanced combustion equation for pentanol

Recently‚ an opinion that is harmful to our health was raised by Dr. Arthur Hull Hayes‚ Jr‚. former commissioner of the U.S. Food and Drug Admistration in 1981. The American Heart Dissociation‚ the American Medical Association also joined the low-salt appeal. They believe that sodium salt is connected with heart disease‚ circulator disorder‚ stroke and even early death. By many doctors and researchers are now beginning to

Throughout this experience and this “mock” rite of passage the boys experience alienation while being on an island. Alienation is the condition of estrangement or dissociation from the surrounding society. Alienation not just occurs to the boys as a whole but also to Piggy who is ostracized and made fun of by most of the boys. This can be seen in another sociological concept known as an out group. Piggy becomes parts

Lab 19A Answers: 1) If we increase the molarity of NaOH from 0.1M to 0.2M‚ it will actually take less number of drops in order to change the color of the solution. This is because the more concentrated a substance is‚ less of the substance is needed to cause an equilibrium shift. 2) When you add 6.0M NaOH into the iron (III) thiocyanate ion equilibrium system‚ the concentration of Fe3+ ion decreases. This causes the equilibrium system to shift to the left (reactant) side. This is why the solution
