In the coordination compound K2[Co(en)Cl4] the coordination number (C.N.) and oxidation number (O.N.) of Cobalt are C.N. = 6; O.N. = +2. C.N. = 6; O.N. = +3. C.N. = 5; O.N. = +2. C.N. = 5; O.N. = +4. C.N. = 4; O.N. = +3.
The concentrations of each were then determined as follows: [Fe^3+]= 6.8 x 10 ^-4 M, [SCN ^-]= 3.3 x 10 ^-4 M, [FeSCN ^2+]= 3.0 X 10 ^-5 M. Determine the equilibrium constant for this reaction.
If more than one precipitate is expected, list the numbers in increasing order and separate them with commas. For example, 3,4,5 is ok but 5,4,3 is not. pH = 7.00: pH = 9.00: What is the pH to the nearest 0.1 pH unit at which Cd(OH)2 begins to pre
A mole of photons is called an einstein. Calculate the radiant energy of an einstein if the photons have a wavelength of 608.7 nm.
In a titration of HCL, I have a molarity of 0.991 NaOH and a volume of 7.6 mL to reach an equivalence point for the titration. I need to figure out the number of moles of NaOH from these figures. Please show all stoichiometry steps.
When the Vmax and the Km of an enzyme are not known, it is essential to determine the enzyme's initial velocity (Vo) at different [S]. To determine the initial velocity, one would have to: Select one: a. Use the Michaelis Menten equation
Given the following substances in order of increasing acid strength,HOCl(aq) < HC2H3O2(aq) < HC2O4-(aq) < HOCN(aq) < HNO2(aq) < HCl(aq) Which species listed below is the weakest base of that set
Air initially occupying 1 m3 at 150 kPa, 20°C undergoes an internally reversible compression during which PV^n = constant to a final state where the pressure is 600 kPa and the temperature is 120 C determine the value of n.
Once the ionic solid has dissolved, the anion that is formed is able to react as a base, with water as the acid. Write the net acid-base reaction that occurs when dissolved NaClO reacts with water
Chemists studied the formation of phosgene by sealing 0.73 atm of carbon monoxide and 0.98 atm of chlorine in a reactor at a certain temperature. The pressure dropped smoothly to 1.32 atm as the system reached equilbrium. Calculate Kp(in atm-1) fo
