present. Since heat was applied to the beaker (energy went into the system), the reaction was classified as endothermic. Decomposition Reaction: Balanced Chemical Equation Cu(OH)_(2 (s))→CuO_((s))+H_2 O_((g)) Reaction 4: The Formation of CuSO4: Reaction 4 involved an acid-base reaction between CuO, the Arrhenius base, and H2SO4, the Arrhenius acid to form the CuSO4 salt and water (H2O). After the acid had been added into the solution, the solution became uniformly clear and light blue. It was…

The ideal gas law is shown as PV=nRt, where R is considered the gas constant in the equation or the problem that is being asked in a question. Solutions 5.What factors affect the rate at which a solution dissolves? When you heat or cool the solution it will increase when heated and decrease when cooled, also you can break the pieces of the…

reaction occurs when two solution mix together. Chemical reaction is changing their properties and reagents concentration which create new products. There is a titration method to check the kinetic reaction. For example, of chemical equation as aA + bB → cC+ dD This equation describes the general term in rate of concentration. A and B is the reactant and C and D is the product thus, expresses the proportion. K is the rate constant and t is the change in time. reaction rate=-1/a d[A]/dt=-1/b…

andrographolide concentration in the supercritical solvent (Ce) at the exit end of the extraction column can be calculated by solving equations (2) to (5), and is written by: (6) Integrating Ce with respect with time will result the total amount of extracted andrographolide. Then, the yield of extracted andrographolide (F(t)) can be estimated using the equation below: (7) The optimum values of desorption rate constant, kd (1/hour) for each experiment were…

In this equation, x and y denotes the number of moles of RE and Mn atoms per formula unit of the structure, respectively. The RE and Mn represent the theoretical magnetic moment of trivalent free RE3+ ions and divalent Mn2+ ions respectively. The experimental values of total magnetic moments were found to be smaller than the calculated values (Table xyz). The crystal field effects can lead to lower value of magnetic moments for RE3+ ions in these compositions as compared to free RE3+ ions,…

temperature monitored water bath shaker. The solvent was filtered out after equilibrium and tested for Cu (II) ions concentration using the Atomic absorption spectrometer. Data analysis was carried out using pseudo-second-order model and Arrhenius and Eyring equations. The adsorption process was efficient, endothermic, and followed the Langmuir isotherm model with TFS-CE having maximum adsorption capacity of 64.1mg.g-1 at temperature of 300K and pH of…

Electrical properties Figure. 8 shows the temperature dependence of resistivity of the Co(II), Ni(II) and Cu(II) complexes. As seen, the data reveal a semiconductor behavior where the resistivity decreases with the increases of temperature. The decrease of the electrical resistivity with increase of temperature is resulted from the increase of the charge carriers that can overcome the energy barrier and participate in the electrical conduction where in metal complexes, the metal…
