Calculate the conditional formation constant Kf' for the formation of an EDTA complex with copper(II) at a pH of 5.00, if log Kf = 18.80. Show Work.
Select the reagent from the list below that could be the basis of a simple chemical test that would distinguish between each of the following:
if 11.2 L of N2 are reacted to form NH3 at STP, how many liters of hydrogen will be required to consume all of the nitrogen
What is the final state of the system when the piston has stopped and there is a balance of forces across the piston? Do not neglect the fact that during motion there may be some friction between moving parts. Consider cases in which the piston is..
On the basis of the solubility rules, write a balanced molecular equation for the precipitation reactions that take place when the following aqueous solutions are mixed. If no precipitation reaction is likely for the reactants given
A certain substance has a heat of vaporization of 29.00 kj/mol. At what Kelvin temperature will the vapor pressure be 3 times highe
What volume of O2, measured at 25C and 1.00atm, is expelled when 425ml of water saturated with O2 is heated from 0 to 25C?
When the one ore lead (ii) sulfide burns in ixygen, the products are lead (ii) oxide and sulfur dioxide A. How many grams of oxygen are required to react with 0.126 mole lead (ii) sulfide?
Which compounds reacted only with AgNo3 in ethanol. Why. Did any compounds appear not to react under either condition, even when heat was added ? Explain, for each compound, why it might not react by a substitution reaction.
The exothermic chemical reaction CO(g) + H2O(g) CO2(g) + H2(g) has Kc = 0.034 at 25°C. We currently have a flask containing all the components listed in this equation at equilibrium at 25°C. Subsequently, we will either (1) add some H2 to the flas..
