  1. Which question was this? The one that had Mr = 44 Cool, I seem to remember getting A too. Same here, A!!
  2. I suppose it ask the function of these type of hormones What do you mean these types of hormones? They asked what is the main function of these two hormones in the body. I must have misunderstood the question, because I thought they asked to describe the main function of progesterone OR testosterone. I remember the word "or" because I even underlined it, but maybe the question refered to both of them, damn it! Don't worry! The exact wording of the question was as following: "Progestrone and Testosterone are other steroid hormones produced from cholesterol. Outline a function of Progestrone OR testosterone in the human body. " Your welcome! I didn't realise the or until later.. so I wrote both functions, no harm no foul! THANK YOU!!! MADE MY DAY!
  3. And differece between inorganic and organic catalysts? I wrote something that organic catalysts are more sensitive to environmental changes and that they speed up the rate of reaction much more than inorganic ones.

I must have misunderstood the question, because I thought they asked to describe the main function of progesterone OR testosterone. I remember the word "or" because I even underlined it, but maybe the question refered to both of them, damn it! or maybe they have asked only for the one of them... I am not sure now... was it for 1 or 2 points? 1 point and what did you write about the question of nurtients deficiency? i dont remember what was exactly the question about but i remember i put genetically modify food and i wanted add ' add nutritional supplement' but this was given in the statement above the question so i was confused... I wrote GMO too and I also wrote that add to commonly consumed foods such as adding iodine to table salt But yeah it was confusing because two things were already given O.o What did you write about the DNA one strand question and enzyme mechanism?

  7. something like hydrolys it with HCl and heat.

  9. For option B, it was one question about testosterone and progesterone, they asked only to write the role of one of them right? o.O
  10. I said the same thing. 107 for one and <120 and<180 for the other one.both had a lone pair. What did you writr for the question were they asked about the covalent bond between hydrogen and carbon? So the bond angles for the seesaw should be more than 180 so 186 because of the pair of lone electrons that has extra repulsion, less then 120, so 116 and exactly 90 so 186,116 and 90. I was blessed with this question as I wrote all of the shapes and bond angles on paper night before the exam and memorised I think that Pearson's HL book is great for learning bonding cuz in Study Guide they do not pay attention to shapes and bond angles. Damn, you are right What did you guys get on question 7 I believe, on the PH for ammonia solution or something like that?
  11. I said the same thing. 107 for one and <120 and<180 for the other one.both had a lone pair. What did you writr for the question were they asked about the covalent bond between hydrogen and carbon? Shared pair of electrons closer attracted to carbon due to its higher electro negativity though I squeezed that last bit in right at the end, may not get the mark. Regarding the percentage error, I got 60 but I used 0.05 not 0.025 mol to work out delta H (the first of my silly mistakes!!) I believe the correct answer is around 20%. Well I wrote that it was dative covalent bond but Im not sure wHy I wrote it
  12. I said the same thing. 107 for one and <120 and<180 for the other one.both had a lone pair. What did you writr for the question were they asked about the covalent bond between hydrogen and carbon? For the SF4 I wrote see saw, as it has 5 charge centres, 1 non-bonded, and angles of 117, 90 and 180Yeah I wrote see saw too, but I dont know about bond angles some books says its only <120 and <180
  13. On section A first question what percentage error did you get?
