Tips for Asking Questions
- Provide any and all relevant background materials. Attach any necessary files to ensure your Tutor has all the required information to answer your question as completely as possible.
- Set a compelling price. While our Tutors are eager to answer your questions, offering a compelling price 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)
