Chemical synapse

the empirical formula of a compound when the amount of it is known. By dehydrating the copper chloride hydrate sample and using it for an elemental copper-producing chemical reaction, one can isolate the masses of the water, copper, and chloride and determine their mole ratios. Since the Law of Definite Proportions states that a chemical compound always contains fixed proportions of its constituent elements by mass, the mole ratios can be used to find the empirical formula of the copper chloride…

Design- In this experiment we selected the happy sack to use for our experiment, as this sort of ball doesn’t bounce when dropped to the ground and this then gives us more accurate data for us to compare with the theoretical time. To record the closest accurate time and distance we could get, the equipment we chose to use, were two stopwatches so that we could compare the human reaction times and a tape measure to correctly measure the distance that the ball is going to fall from; which counted…

Equipment: // Sodium thiosulfate solution (of concentrations 0.1M, 0.2M, 0.3M, 0.4M). // Hydrochloric acid (2M). // 100cm3 conical flask. // 10cm3 measuring cylinder. // Dropping pipette. // Small piece of plain paper with a large X drawn with think black pen. // Stopwatch. // Goggles. Variables: Independent - The concentration of sodium thiosulfate solution (0.1M, 0.2M, 0.3M, 0.4M). Dependent - The time taken for the cross to not be seen. Control - // Concentration and volume hydrochloric…

DATA ANALYSIS The linear relationships between the time elapsed and the volume of gas indicates a constant enzyme reaction rate. The activity rate of catalase in figure 1 is calculated to be approximately 0.15mL/sec. The following figures show how this rate of reaction is affected by different external factors. The results in figures 2 and 5 show an increase in either enzyme concentration or substrate concentration will increase the enzyme activity. In figure 2, the 0.75% enzyme concentration…

1. The actual volume of oxygen consumed per minute, V̇O2, is calculated using an equation that is a reasonable estimate, but one must keep in mind that said equation is based on the fact that both the volume of inspired and expired air are equal and that there is no change within the gases that are stored inside the body. The same can be said for the equation that is used to calculate the volume of carbon dioxide that is produced per minute, V̇CO2. However, since it there is in fact a change in…

Hydroboration/Oxidation of an Alkene Introduction: An alcohol can be added across the double bond of an alkene via hydration, which is the addition of a proton and alcohol group to the double bond. This reaction can yield either a Markovnikov alcohol or an Anti-Markovnikov alcohol. If the reaction is carried out in acidic conditions, the reaction yields a Markovnikov alcohol. The mechanism includes the formation of a carbocation intermediate, which has a lower activation energy when it is…

Umama abid Lab Partners: Olivia, Emily Ms. Olenick SBI4U 9/23/2017 Analysis The solution in the dialysis tube turned bluish black in color due to the transfer of iodine from the beaker to the bag which contains starch and glucose . The solution in the beaker turned brown after Benedict’s test ( table 1) . This indicates that the dialysis tubing was permeable to both glucose and iodine but not starch ( work helper, 2017) . Starch didn't pass because the solution in the beaker which…

fungal and mammal Introduction The first enzyme that was produced industrially is amylase from a fungal source in 1894, it was used to treat digestive disorder. Amylase is an enzyme that breaks down starch into sugar and starts the process of chemical digestion in human salvia. Starch breakdown of amylase has received a great deal of attention because of their technological significance and economic benefits, and is also used for the commercial production of glucose. In storage tissues such…

In order to know more about nitrate, we actually must understand what a polyatomic ion is. A polyatomic is an ion which consist of molecules, thus, it may also be referred as a molecular ion. Two or more atoms covalently bond or share electron pairs with each other to make up a polyatomic ion. Once they have bonded, they become considered as a whole single ion. Moreover, it is known to have a charge, most polyatomic ions have a negative charge but there is an exception with a positive charge. In…

For the reactive flash volatilization (RFV) process based on the knowledge that the catalyst bed is preheated to high temperature, pyrolysis of the heated cellulose particles on the surface of the bed is expected to be fast enough that it will not be a rate-limiting step. Hence, the kinetics of the RFV of cellulose reduces to gasification of the produced volatile organic compounds (VOCs) on and in the catalyst bed. To represent the RFV of the VOCs from flash pyrolysis of cellulose, Aspen Plus…
