A BaSO4 slurry is ingested just before the gastrointestinal tract is x-rayed because it is opaque to x-rays and defines the contours of the tract. Ba2+ ion is toxic, but the compound is nearly insoluble. If ?G° at 37°C (body temperature) is 59.1 kJ/mol for the process below.
BaSO4(s) reverse reaction arrow Ba2+(aq) + SO42-(aq)
What is [Ba2+] in the intestinal tract? (Assume that the only source of SO42- is the ingested slurry.)
Explain the large disparity in the numerical results pf Part (a). Discuss the advantages and disadvantages of the three energy sources.
Calculate the Gibbs Energy of reaction at 298 K for the following using 2 methods. First use enthalpies and entropies of formation and DrGo = DrH o - TDrS o to calculate DrG o.
A first order reaction A-> Product has a half-life of 19.8 min. What is the rate of the reaction when [A] = 0.632 M
The addition of anhydrous calcium chloride to the crude product obtained from the separation procedure often results in the product becoming clear (transparent). What causes the clearing?
a)A 10.0 g sample of a mixture of methane (CH4) and ethane (C2H4) reacts with oxygen at 25C and 1 atm to produce carbon dioxide and water (liquid). If the reaction produces 520 kJ of heat, what is the mass percentage of methane in the mixture?
Give the basicity order? List from most to least basic. 3. Explain the basicity order in terms of resonance and inductive (polar) effects and solvation effects.
A compound of molecular weight 280 g/mol a concentration of 15.0 micrograms per ml absorbs 65 percent of radiation at a certain wavelength in a 2 cm cell.
After precipitation is complete, the concentration of the OH- is -0.10M and the measured cell potential is 1.05V. Calculate the Ksp value for Zn(OH)2(s). Zn(OH)2 > Zn^(2+)(aq) + 2OH-(aq) Ksp = ? PLEASE show ALL work, I rate ALL 5 stars.
