The standard molar enthalpy of formation of NH3(g) is -45.9 kJ/mol. What is the enthalpy change if 20 g N2(s) and 10 g H2(g) react to produce NH3(g)?
hydroboration of 1-methylcyclopentene leads to trans-2-methylcyclopentanol; see attached file. 1. explain from the orientation of the reagents why only the trans-isomer is formed. 2. in actuality, two different trans-2-methylcyclopentanols are formed in equal amounts. draw the structures...
if 5.33 g sample of sodium nitrate is dissolved in enough water to make 125 mL of solution, what will be the molarity?
The rate constant for the elementary reaction is 7.1 multiplied by 109/M s at 25 C. 2 NO(g) + O2(g) 2 NO2(g) What is the rate constant for the reverse reaction at the same temperature?
the complete combustion of octane
- Which anions generally form precipitates
A solution is prepared by mixing 50.0 mL of 0.20 M Pb(NO3)2 with 50.0 mL of 1.5 M KCl. Calculate the concentrations of Pb2+ and Cl - at equilibrium. [Ksp for PbCl2(s) is 1.6 10-5.]
what is the organic synthesis of Bonine?
How much heat (in Joules) is gained by the water where a chemical reaction takes place in 100 mL aqueous solution and has a temperature increase of 14C? [hint: ignore any effects by the calorimeter]

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)
