ABSTRACT Reaction time is one of the important methods to study a person’s central information processing speed and coordinated peripheral movement response. Simple reaction time is usually defined as the time required for an observer to detect the presence of a stimulus. The main purpose of this study is to determine whether there is a significant relationship between distance and the reaction time of an individual to light whereas distance is the independent variable and RT is the dependent

First devised in 1889, the Winkler method is considered the "gold standard" for measuring the concentration of dissolved oxygen in a sample of water. Through a series of chemical reactions, the O2combines with iodine to form a golden yellow chemical. Therefore each oxygen molecule is associated with an iodine molecule, and we can measure oxygen by measuring the iodine. When the iodine is neutralized by the addition of sodium thiosulfate, the golden color disappears , and we can determine how much

Data: See attached sheet Discussion: The catalase enzyme does not work at high temperatures around or above 50 degrees celsius. We proved this in our lab when the slope changed from 0.021 kPa/sec at 34 degrees celsius to negative 0.009 kPa/sec at 54 degrees celsius. With just a change in 20 degrees the slope, or how well the enzyme is working went from really good to really bad. The catalase enzyme works best around a pH of 10. At a pH of 4 and 7 the slopes were 0.007 and 0.009 kPa/sec. At the

Figure 3e shows the effect of temperature on the Q values of hydrogels after the pasting reaction. The Q values increased and then decreased with increasing temperature, and reached to the maximum at 50 °C. Less free radicals could be produced at such a low temperature, and thus may decrease the rate of grafting reaction, resulting in low Qs. With increasing temperature, more free radicals could be produced and the monomer reactivity may increase; therefore, the grafting and chain growth rate increased

crushed up TUMS tablet. Then add 25 milliliters of hydrochloric acid to the crushed up tablet that is dissolved in water. The outcome of adding more than enough acid is to eliminate the buffer and make the solution go from basic to acidic. During this reaction carbon dioxide gas is formed and to remove the gas, heat it on a mild boil for one minute. After being heated, all the moles of base react with the hydrochloric acid and what is left is the unreacted hydrochloric acid. This technique is referred

many types of plants. Upon exposure to oxygen, catechol in plant cells is oxidized, and, with catecholase, produces benzoquinone. Benzoquinone is used as a protection against invasion and infection by microorganisms (Stegenga, 84). The oxidation reaction of catechol may be represented by the following equation: Catechol + ½ O2 Benzoquinone + H2O Benzoquinone is a brown color, allowing for observations about its presence to be determined by use of a spectrophotometer that
