the calculation of the theoretical yield of calcium carbonate. The mole ration between CaCl2-.2H2O and CaCO3 is 1:1 that means that if we have 0.00680 moles of CaCl2-.2H2O we will get 0.00680 moles CaCO3 Convert the moles of CaCO3 to grams of CaCO3 = 0.00680 moles CaCO3 x 100 g CaCO3 1 mole CaCO3 = 0.68g CaCO3 Show the calculation of the percent yield. = Actual yield/Theoretical yield x 100 = 0.5/0.68 x

Kinetics of an SN1 reaction: the effect of solvent on rate Object The purpose of this experiment is to determine the rate of hydrolysis in acetone/water (50/50 v/v and 60/40 v/v). Background and Theory An SN1 reaction of tert-butyl chloride takes place in two steps. First‚ the Alkyl Halide will leave the molecule. In this step the bond is breaking‚ which takes a longer amount of time‚ so it will determine the rate of the reaction. As a result‚ it forms a tertiary carbocation‚ since this

CHAPTER 4 (MANKIW) INFLATION RATES AND INTEREST RATES: THE FISHER EQUATION NOTES by: Chadia Mathurin Economists differentiate between real and nominal interest rates where: real interest: is defined as the increase or decrease in a consumer’s purchasing power experienced as a result of changes in the interest rate. nominal interest: is defined as the interest payed by the bank. Let: i denote the nominal interest rate r the real interest rate pi ‚ the inflation rate The equation for the

Publication No. 91860 Rate of Reaction of Sodium Thiosulfate and Hydrochloric Acid Rate Laws Introduction The purpose of this demonstration is to investigate the effect of sodium thiosulfate concentration on the rate of reaction of sodium thiosulfate with hydrochloric acid. The reaction‚ which produces solid sulfur‚ will be followed by measuring the time needed for the reaction mixture to become opaque. The results will be analyzed graphically to determine the order of reaction— the mathematical relationship

To begin the experiment‚ the reaction apparatus was assembled (as shown in Figure 1 below from the lab manual) consisting of a 3.0 mL conical vial charged with p-cresol (80uL from Eppendorf pipette)‚ 25% aqueous NaOH (130uL)‚ and a spin vane. The solution was mixed thoroughly and tetrabutylammonium bromide (9mg) was added along with n-propyl iodide (75uL) and it was equipped with a flask with a water reflux condenser. The solution was heated (95-100°C) while vigorously stirring it. After 60 minutes

energy and heat associated with chemical reactions and/or physical transformations. A reaction may release or absorb energy‚ and a phase may change‚ such as in melting and boiling. Thermochemistry focuses on these energy changes‚ particularly on the system ’s energy exchange with its surroundings. In combination with entropy determinations‚ it is used to predict whether a reaction is spontaneous or non-spontaneous‚ favourable or unfavourable. Chemical reactions can be divided into two based on the
