In a editorial, 3 years ago, Marc Lipsitch (2014) blasted certain types of virus research as too risky. My immediate gut reaction was that Prof. Lipsich was unduly scaring the public by overstating the risks. Upon further reflection, I've come to the opinion that Prof. Lipsitch's concerns may well be justified. Based on the articles by Lipsitch (2014) and Wahlberg (2014) answer the following two questions:
(a) What are the benefits and the risks of this research?
(b) Do you feel this research should go forward (and why)?
Gallium has two common isotopes Ga-69 and Ga-71. Suppose we wanted to use the Ga-71 isotope for some reason, and obtained a pure 6.0g sample of Ga-71.
The Ksp of Ca(OH)2 is 5.5x10^-5. What is the concentration of the OH^- (aq) when in a saturated solution of Ca(OH)2 (aq)
Adipic acid, HOOC(CH2)4COOH, is among the top 50 manufactured chemicals in the United States (nearly 1 million metric tons annually). Its chief use is in the manufacture of nylon. It is a diprotic acid having Ka1=3.9×10?5 and Ka2=3.9×10?6.
propose a structure for an amine of formula C4H9N, which liberates a gas when treated with NaNO2 and HCl. The 13C NMR spectrum is as follows with attached protons in parentheses: delta 14 (2), delta 34.4(2), delta 50.0(1)
If the initial pressure of iodoethane is 894 torr at 245°C, what is the pressure of iodoethane after three half-lives?
What might have happened if the temperature of the oven were set to 210 degrees
Problem- In a constant pressure calorimeter, 7.30 g CaCl2 is added to 125.00 mL of H2O at 23C. Determine the final temperature of the solution if the enthalpy change associated with the dissolution of the CaCl2 is -82.8 kJ/mol.
Solve an equilibrium problem (using an ICE table) to calculate the pH of 0.16M CH3NH2 and the pH of 0.16M CH3NH3Cl
