The equilibru7m constants for a series of reaction of the general type AB +CD---> AD+BC were measured and are shown below. In which reaction is the concentration of the products the largest at equilibrium.
3.5x10^3 5.7x10^-2 0.011 1.2
Is it possible for a salt of formula AB3 to have a face-centered cubic unit cell of anions with cations in all the eight available holes. Explain.
Explain what are the concentrations of OH- and H+ in a .00084 M Solution of Ba(OH)2 at 25 degrees Celsius. Presume complete dissociation
Thus, as long as the concentrations of HA(aq) and A-(aq) are not consumed, the pH change is minimal compared to addition to a non-buffer solution. Why is the buffer most effective when pH = pKa?
Treatment of D, first with aqueous acid and then with KMnO4, yields 2 carboxylic acids identified as acetic acid and pentanoic acid. (KMnO4 cleaves 1,2-diols to yield carboxylic acids.) Propose a structure for compound D. Don't worry about sterioc..
Exactly 500.00mL of 1.000M perchloric acid is used to dissolve 22.10g of the mineral malachite, Cu2CO3(OH)2 (molar mass=221.0g/mol). What volume of 1.000M sodium hydroxide, is necessary to completely neutralize the excess acid?
Explain how many kilograms of chlorine are in 25 kg of each of the following chlorofluorocarbons (CFCs)
Calculate the partial pressure of each gas in the container. Express the pressure values numerically in atmospheres, separated by commas. Enter the partial pressure of methane first, then ethane, then propane.
Question- 1) What is the magnitude of the energy of a bond formed between a potassium (K+) cation and an iodide (I-) anion? The ionic radii of K+ and I-?, are 152 pm and 206 pm, respectively. Assume the Born exponent n is 10. Please write your ans..
A bag of potato chips contains 595 mL of air at 30.0 degrees celcius and a pressure of 770 mm Hg. Assuming the bag does not break, what will be its volume at the top of a mountain where the pressure is 438 mL and the temperature is 8.00 celcius?
Combine your results in b with the total experimental value of BEta Mu ^x to obtain the attractive contribution to BEta mu ^x and estimate the value of cohesive coefficient t?
Two of these students will report, within experimental error, the same increase in solution temperature for the neutralization. Which are the two students? Explain.
According to Charles Law, for a fixed quantity of gas at constant pressure, which of the given quantities is constant? V/T, VXT, or V+T
