  1. Hi there, I'm really struggling with topic 1 stoichiometry and I really need help! Will you please help me with the following 3 questions? 1. 5.0dm3 of 2.00mol dm-3 sodium carbonate solution, Na2CO3 (aq)was added to a volumetric flask and the volume was made up to 500 cm3 with water. What is the concentration in mol dm-3, of the solution? 2. How many grams of sodium azide, are needed to produce 68.1dm3 of N2 (g) at STP? Molar V at STP = 22.7 dm 3 mol-1 ; Mr(NaN3) = 65.0 2NaN3 (s) → 3N2 (g) + 2Na (s) 3. 2.478g of white phosphorous was used to make phosphine according to the equation: P4 +3OH- +3H2O ---- PH3 +3H2PO a) Calculate amount in mol of white phosphorus used b) This phosphorus was reacted with 100.cm3 of 5.00 moldm-3 of aqueous sodium hydroxide. Deduce, showing your working, which was the limiting reagent. c) Determine excess amount in mol of the other reagent d) Determine the volume of phosphine, measured in cm2 at STP that was produced. For #3, I'm stuck after the first a), and I have no clue how to start off with number 1 and 2. Is #1 a question related to titration or concentration? For question 2, do I use the volume of gas law with the volume ratio to solve the question? Thank you, please help me!!
  2. I've been struggling with my chem ia topic - every idea I have turns out to be too hard to pursue with my current knowledge and skills or I just have no idea how to come up with an actual method to measure something. My teacher isn't too helpful either - she isn't too keen to give me any tips or help me develop my ideas into a valid research question. Lately, I've been thinking about investigating how does the presence of different metal ions affect the rate of hydrolysis of esters. Is it a good idea, should I take it seriously and look into it? And what method could I use?
  3. Hey, I am desperately in need of help on how I should write up the report for my biology IA. I did "How does the PH of the provided plant nutrition affect the germination of pea seeds?" Any ideas on how I should write it up?
  4. I am going into my first year of IB. I had planned to take exercise science and art, but my school just let me know that this is not available. I must choose either bio and art, or psychology and exercise science. (We are on A day B day schedule so I must choose one of theses pairings) Which of these pairs has a higher course load? And which is harder content in general? Also, if there are any opinions not based on these questions I most definitely want to know that too! I am interested in all of these classes pretty equally, and just making sure I choose a pairing that will not be completely overwhelming. Thank you!!
  5. Hi, so my friend was doing her IA on a company called Godrej Interio. But she just now found out that she was collecting data from their franchisor, not from the company itself. The 2nd draft is submission in another 2-3 days. Can anyone suggest on how to tackle this even if she could extend the deadline by 3-4 days? That would be really helpful
  6. Hello All, As you know by the title, I need EE help. Basically, I chose to do a biology EE cause it is my passion. At the beginning of our topic selection, I met with my advisor and told her that I wanted to do something with E.coli. Over the next several meetings I had with her, I decided upon studying how the different pH's of different foods inhibit E.coli growth. Long story short, on the LAST day of school my advisor tells me that I can no longer choose a topic that has to do with bacteria or else I will not score well. Apparently, IBO changed their guidelines that effected my class and when I asked my advisor about it she said: "yea, they can do that and we have to oblige". So I took about 1 day or so thinking about another topic I could do and landed on studying how different elements such as Nitrogen, Potassium, and Phosphorus inhibit the growth of a lima bean plant. So I got my materials and everything I needed to conduct my experiment and for the life of me, I have not been able to grow any seeds. All of the seeds which I have tried germinating or planting have died/failed/rot. That was 2 months ago. I have kept trying since then but to no avail. My rough draft of the EE is due on the first day of school 8/12/2019 and I do not know what to do. I have emailed my advisor multiple times and each time she has told me to either change my watering habits (which I have, I water once a day, and keep them in the sunniest part of my patio so they get the most sun), or to restart my seeds, or even keep trying. She even said she is baffled as to how I have not been able to grow such an easy plant. And now I am on the brink of a total mental breakdown and do not know what to do. My advisor told me I need some sort of data represented in my EE and if I have none, it will not be good. Can someone explain to me what would happen if my experiment for my EE does not go well? I would really appreciate it. Furthermore, I am in Florida, and all of the gardening departments of every store and independent gardening markets have stopped selling seeds as the season is coming to a close, which is making me even more frustrated now that I have no way of obtaining seeds. Someone, please help. Thank You.
  7. Hi! So, I have been thinking of possible Maths IA topics for quite a while and have just decided to do it on Vectors (because I'm relatively better at it?). I have heard that quite a few game developers utilise vectors during the game development process, and so it would be in my greatest interest to base my IA on vectors in video games. However, I'm not quite sure on how to go about writing this. I have a basic outline of the structure of my IA (start with 2D then advance to 3D), but I'm starting to worry that it may not be as good as a topic as I hoped it would be. Could someone tell me if this is a feasible topic? What should I do to maybe add more depth to this investigation? Thank you!
  8. Hey guys! I just recently wrote my exams, and I answered the details on the cover sheet incorrectly. Specifically, I only put in the section B questions I answered in the boxes, but I did all of them. My IB coordinator told me today after my exam had already finished, when I asked him, to just write "all", but I cannot change anything anymore. Will the examiners just mark the section B on my paper, because that could be catasrophic for my results. Can somebody give me a concrete yes or no answer if this affects the marking of my paper. I am freaking out! Please someone help!!!!!!!!!
  9. Good day, I have to perform an FOA and I decided to use the Malala speech to analyse. I have been confused to whether this is linked to part 1 or part 2 of the course. So which part of the course would this particular FOA idea be more relevant to link to? Is the analysis of a speech supposed to be for part 1 or part 2 of the course? With which learning outcomes and topic (possibly)?
  10. Hey, My topic for my Chemistry SL IA is the quantitative analysis of vitamin c in raw tomatoes compared to cooked tomatoes. I thought about making 5 repetitions because of the certainty. I will get 5 results overall. Is that enough? Or do I need more repetitions? Is this topic even useful? If not, what do you request? I'm open for ideas! PS: I have no time left, deadline by tomorrow. Thank you
  11. I'd asked my Bio teacher if I could do my IA on the effect of music on plant growth and at the time she'd said yes, but after I submitted my information sheet she said that it was an idea with a shaky foundation and that I need to turn in a new idea ASAP. Please help!!! I was thinking something along the lines of photosynthesis..... I don't know, I'm just really confused right now. Is there anything I can do that's relatively simple but not like, utter trash?
  12. Hi, I need to write a written assignment for the external assessment which is the 1500 word literary essay on a work studied in part1. I'm writing my essay on Death and the Maiden by Ariel Dorfman. My guiding question for the essay is "How does Dorfman create conflict between Paulina & Gerardo through the use of dramatic dialogue and how is it resolved?" I plan to constrain it to act 1 scene 1 while linking it to other parts of the play. Do you think that this is an appropriate topic? And I'm not sure about the structure of the essay. What do I start writing with? Please help ASAP!! Thanks
  13. I made the stupid decision of writing my EE on a subject which my school doesn't offer, and regret it... but whatever! I'd love it if somebody who takes the course or goes to a school that offers it could help me out by sending me some kind of study guide, curriculum, a sample essay of any kind or even putting me in contact with somebody would help-- I'm just looking to better understand the subject and hopefully find someone that can give me some tips or even read my essay! Thank you so much guys!!
  14. I'm doing my IA this summer, meaning I don't have a way to contact my teacher with questions. Does it matter how many words I have in part A and B and C if the word count all together is 2,200? My total words at the moment are 2,300 and I have 1,600 in my investigation (I know, I've already had like 5 panic attacks about it) whilst the other are shorter but still have everything they need I think? Advice on what I should do? My deadline is on August 10th.
  15. Hi guys so a couple of weeks ago I did a physics IA on investigating Malus' Law and I am right now in the process of writing that IA. However, I am stuck on trying to think of an interesting way to process my data as other than forming the cosine curve, I do not know what else I can investigate or explore through processing my data and making other graphs. Can anyone help me with this and give me an idea on what I could do? It can be anything with which I can use my data to show another equation etc. To give an idea on what data i have, I have the wavelength of the laser used, the distance to the photometer, the diameter of the laser light and of course the intensity in lux.
  16. Hello, Do you think that for Paper 3 of History it is enough to work in two topics (being able to choose 3 questions of 4)? Or it's really risk? Because the other option is starting a new topic. Should I work really hard on these 2 I already know, or start another one? i have the exam in 4 weeks. What do you think? Thank youu!
  17. So, right now I have an assignment in history where I have to write about Friedrich W. Foersters "Europe and The German Question", and now I came to a part where it says "Limitation of content" and idk what I have to write there. I tried to find some answers, for it. But there's nothing.
  18. Hello, I have to conduct an experiment for my Biology IA and I was thinking it should be about Caffeine. I am a Caffeine intolerant and I would want to make some experiment of "how to reset caffeine tolerance" and to see if its possible. Perhaps I could measure my heart/ pulse rate for 3-4 days and see if there is any difference. Now I really need to now if this idea would work for the Biology IA and I would really appreciate if any of you could suggest how I should write the research question for this experiment in this case. Now first of all, can I do this if I have human consent form ( for myself or for other humans)? Or is there a problem with using this on humans? The thing is I have to conduct this experiment on my own, so please if you have any other suggestions or ideas that I could possible do without the help of an actual Lab, I would truly be thankful for it. (research questions about any topic in human physiology maybe? ) I am an SL Biology student by the way.
  19. I'm trying my hardest to do the biology assignment (extraction of strawberry DNA) and am really really struggling with the evaluation. These are my data.

  20. hello, I'm facing a huge problem in deciding what to do for my physics EE. i thought of many topics but nothing seems to fit into the criteria of a good topic. the latest one i thought of was: "to what extent is it true that a body, which initially moves at a particular speed starts moving with a speed closer to that of light, makes the factors of time dilation and length contraction become evident?" I am really confused about what to do.as my school doesn't have any proper apparatus for a good experimental topic.
  21. I have completed my IOP a few days back and I have worked incredibly hard on it. Many of my classmates prior to my presentation highly praised my ideas and unique execution. I love presenting and especially have a passion for English. Unfortunately, I went over time by two minutes and I was wondering how many points that would take off of my score. I aim for a seven on my IOP, and I would like to know if I still have a shot at it.
  22. I am having trouble revising my conclusion for my maths IA. The feedback was basically that my conclusion is too superficial, which I can see. However, I do not know how to improve my conclusion. Does anyone have any tips or pointers? Please help me
  23. I am on the verge of choosing my IB subjects: Math HL Economics HL Computers SL/HL Spanish ab initio English Language + Literature SL Should I choose Business Management, as according to popular belief, Business Management is considered a soft subject and my application may not meet the requirements? And if not, which subject should I choose?
  24. I am in year 11 and I am doing AQA GSCE Psychology, which I really am not enjoying. I get A's and a few A*'s. I started doing Economics GSCE but changes to Psychology within the first two weeks because our teacher was extremely bad, meaning I have no prior economics knowledge. I'm extremely oriented towards humanities and my math isn't that good. I want to study Politics or Law in university. Right now, I really don't want to do Psychology for IB (we need to choose our subjects by next week) and I have a read a bit of Economics and it seems really interesting. My strong point is my memory. SO 1)How hard is it to get a 7 in HL econ? 2)Should I do it? (taking into consideration all of the above) 3)Will the fact that I have a strong memory help me ? 4)Will I get a disadvantage because of my really average math skills? 5)Anything other you want to advise me
  25. Hey guys! So I was earlier doing a micro economics EE, which had to be discarded because Primary data was becoming a problem. Now My teacher suggested that I do a development economics ee because it'll be quicker. Can someone please help me out with the topic and the structure?
