Find the equilibrium concentrations of rm A and {\rm B} for a = 1 and b = 2. Assume that the initial concentration of rm A is 1.0 {rm M} and that no {rm B} is present at the beginning of the reaction. kc=2.3
How many milliliters of 0.50 M HCl solution are needed to titrate 100 mL of 0.20 M NaF to the equivalence point
Assuming no elasticity forces in rubber, what volume should a 1.0L ballookn at 25 degree Celsius and 1.00 atm pressure be if immerses in liquid nitrogen
Consider the cell described below: Al| Al3+ (1.00 M) || Pb2+ (1.00 M) | Pb Calculate the cell potential after the reaction has operated long enough for the [Al3+] to have changed by 0.60 mol/L.
Stripping voltammetry is a trace electrochemical technique in which the current is linearly proportional to concentration. A solution of 1.0x10-7 M Pb(II) gave a current of 0.139 mA.
In PLP catalyzed reactions, the bond broken in the substrate molecule must be perpendicular to the plane of the pyridinium ring. Describe why this arrangement stabilizes the carbanion
Given the initial rate data for the decomposition reaction, A = B + C, determine the rate expression for the reaction [A],M = .0625, 0939, .125; -changeA/changet M/s = 5.44 *10^-7, 8.16 * 10^-7, 1.09*10^-6 (respectively)
