What volume of osygen is needed to react with the solid sulfur to form 6.20L of sulfur dioxide?
1.a)What is the pH of a carbonate buffer solution prepared by mixing 1.5 mol Na2CO3 and 1 mol of NaHCO3 and adding water to make a 1L solution? (pKa of HCO3- is 10.32) b) A 200mL sample of 1M nitric acid was added to the buffered solution above. What is the resulting pH?
Draw a free energy profile for a reaction S to P that proceeds through a single transition state with Delta G knot equal to +2.8 kcal/mol and delta G double dagger equal to 14 kcal per mole. Label the appropiate differences
Calculate the work done when 25.0 g of tin dissolves in excess acid at 1.00 atm and 29 C. Assume ideal gas behavior.
ir spectrum for benzophenone specify bond
To identify a diatomic gas, a researcher carried out the following experiment: She weighed an empty 1.00-\rm L bulb, then filled it with the gas at 1.10 \rm atm and 23.0 ^\circ\rm C and weighed it again. The difference in mass was 1.27 \rm g. Identify the gas.

Tips for asking Questions
- Provide any and all relevant background materials. Attach files if necessary to ensure your tutor has all necessary information to answer your question as completely as possible
- Set a compelling price: While our Tutors are eager to answer your questions, giving them a compelling price incentive speeds up the process by avoiding any unnecessary price negotiations
- 1. For organic chemistry, what is a concerted shift? How do things like acids or heat affect them? What other factors affect them?
2. Which of the following reactions is an acid-base neutralization reaction? Why are the rest of the answers incorrect?
- A. AgNo3 (aq) + NaI (aq) --> AgI (s) + NaNO3 (aq)
- B. S8(s) + 8O2 (g) --> 8SO2(g)
- C. Na3PO4 (s) + 2H2O (l) --> H2 (g) + 2NaOH (aq)
- D. Ca (OH)2 (aq) + 2HI (aq) --> CaI2(aq) + 2H2O (l)
