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
Sample Questions
- 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)
