  1. Only the first hydrogen in sulfuric acid fully dissociates. Bisulphate (the conjugate to sulfuric acid) provides the second hydrogen atom, but is a very weak acid, so will not dissociate in a battery in any meaningful way when compared to the first hydrogen atom. Therefore, in a calculation of this type, you can safely assume that a 4.2 mol/L solution is only account for one hydrogen atom, not two. Hope that helps
  2. Water has 2 lone pairs with an extremely electronegative oxygen creating a much stronger hydrogen bonding network than that of ammonia, with only one lone pair and a relatively weak electronegativity WRT the Nitrogen.
  3. You're making a decision about who you will work with for 5 years or so. If you really vibed with a professor, that's probably your decision
  4. Where can you live? Who would you like to potentially work with? Don't just talk to professors, but talk to various grad students within research groups you are interested in. A highly regarded professor might be a pain to work with for 5 years, or they might be awesome. A generally unhappy group of grad students within a research group might be because of the professor. Most grad students won't tell you directly that they are unhappy, but it's generally easy to ask questions that give you the information you'd be looking for. Also, NYC and Ithaca could not be more different to live. You will be spending 5 years there. Ithaca is MUCH colder than NYC in the winter, and there is MUCH less to do. And NYC is obviously much more expensive, loud, etc, than Ithaca. My quality of life is as to where I'd actually be living for 5 years is much more important to me than what research group I'd be in or which university has a superior department, but that's just me. Figure out what your priorities are and you will be able to answer this question for yourself. They are both highly regarded departments.
  5. The only studying I did was the one practice test provided by them, which I got a 164Q/155V on, and took the actual test the next day and got the exact same thing
  6. It was optional for the program I was applying. "Optional but recommended." was what was written on their website. I straight up just emailed the POI I'd been emailing with to ask him how "optional" it really was, and he told me it was not very optional, so I took it.
  7. Not a suit. Not a tshirt. Business casual is fine. Nice jeans/slacks/skirt and a reasonable shirt/blouse
  8. For a PhD program people care MUCH more about what you actually accomplished in your research during Grad school than who you worked under or the institution you got your PhD at. You can make an impact on a field from any research institution. The benefits for a higher tier institution, tho, could be they are better funded, more modern instrumentation, and improved networking opportunities.
  9. Undergrad Institution (approx. rank/reputation in STEM): University of New Orleans. Not highly ranked Major(s): Chemistry Minor(s): Math GPA in Major: 3.2/4.00 Overall GPA: 3.0/4.00 (returned to undergrad after 18 years off as a senior with a low GPA. 4.0 GPA within the 3 semesters I used to complete my degree) Demographics/Background: White american male GRE Scores: Q: 165 V: 155 W: 4.0 LOR: One from a professor I worked for, one from his post doc I worked directly on a one year project with, and one from the dept chair whom I worked for as a TA Research Experience: One year in a research lab at UNO in conjunction with the Advanced Materials Research Institute in an inorganic nanoscale materials lab Publications/Abstracts/Presentations: None Awards/Honors/Recognitions: Outstanding chemistry senior at UNO (the competition was NOT fierce). Poster/zoom presentations Fellowships/Funding: Funded by AMRI as an undergraduate researcher Pertinent Activities or Jobs: 15 years experience as a flight attendant for a major airline. This likely helped since I have corporate experience, am older, and plenty of experience working on a team with various personalities as well as safety/compliance experience that comes with working corporate Other Miscellaneous Accomplishments: Learned portuguese by myself to fluency. Not sure this helped for chemical/materials engineering, but it sounds cool on an application Anything else in your application that might matter (faculty connections, etc.): Being local within New Orleans likely helped get into Tulane, and my boss at AMRI has tons of connections at Tulane ChemE dept since UNO and Tulane are the only 2 research institutions in New Orleans. Research Interests: Materials Institutions/Programs: Tulane University Chemical and Biomolecular engineering, Accepted with funding. I was told to apply to other institutions by my boss (MIT, CalTech, Stanford, etc) but am too tied down to New Orleans (married/house/dogs) so only applied at Tulane Comments: Accepted offer at Tulane with full funding
  10. Go be friends with any adult. Who cares what their status is as a student, unless they are your student and you are showing them favor in grading or whatever.
  11. In 2003 I had 2 semesters of all F's due to some medical/personal problems and left school (chemistry BS). This definitely tanked my prior stellar GPA. After getting a job as a flight attendant for one of the major US carriers, flying for 13 years, and leaving the airline industry due to COVID, I decided to go back and complete my chem degree and apply for a PhD program in chemical engineering at Tulane. My total GPA at time of application was 2.9, but this included 3 recent semesters (spring, summer, fall 2021) of all A's in advanced science/math undergrad courses. I got accepted into the program at Tulane with full funding, despite my low GPA. I only applied at Tulane, but my advisor at my graduationg university told me I'd likely get into any graduate program I applied to. He told me to apply to CalTech and the like, but I'm tied down to New Orleans already so didn't apply anywhere besides Tulane. Graduate programs will likely look at the entire package of an applicant, and not just a low GPA. If your bad semesters were last year, it would probably be a different story.
