Initially a container contains 0.46 M HI and no product. What is the equilibrium concentration of H2?
what is the maximum mass of an object traveling at 549 m·s-1 for which the de Broglie wavelength is observable?
Why ammonium ion is NOT classified as a Bronsted-Lowry base? 2.Why sulfur hexafluoride DOES NOT obey the octet rule?
Calculate the [Zn2+] in a solution of ZnC2O4 held at a pH of 3.00. Remember C2O4^2- is a weak base so you must consider other equilibria. (Ksp(ZnC2O4)=7.5X10^-9, Kb1=1.8X10^-10, Kb2=1.8X10^-13).
calculate the theoretical yield of c2h5cl when 140 g of c2h6 reacts with 234 g of cl2, assuming that c2h6 and cl2 react only to form c2h5cl and hcl.
The heat of vaporization for the compound is 27.49 kJ/mol. Calculate the heat required to convert 26.78 g C2Cl3F3 from -59.34 oC to 83.11 oC
Draw the six conformers in newman projection for the 60 degree intervals from 0 to 360 degrees for carbon atoms 3 and 4. Clearly show which carbon is represented by the "dot" and the "circle" Show which C
What is the pH of a solution obtained by adding 5.00 g of HI to 295 mL of a 0.786 M solution of nitric acid?
What is the maximum concentration (in M) of chloride ions in the solution that contains 0100 M Pb2 +? The Ksp for lead (II) chloride is 1.0 x 10-4.
Prepare 1.00L of a pH~12 buffer with a total phosphate concentration of 0.050 M.You have at your disposal the following compounds
The reaction of 8.10g of Carbon with excess O2 yields 12.80g of CO2. What is the percent yield of this reaction?
Why do lithium and sodium exhibit similar chemical behavior? What is the stadard potential of 1/2 O2 My table says 1.229
From the examples you state, select one acid, one base, and one salt and describe specifically how and where they are used in therapeutic processes. Define a buffer and explain how a buffer works.
