Attached is the image of the desired structure, my question is based on what is pictured as (CH3)2HC- I represented this group as C3H7 which does seem like the logical equivalent, but just being safe here. Am I right?
Thank you!
Aah Borek! My old friend! ;)
Well I know the logic doesn't apply because the answer book says it doesn't but the first para answered by question. However this is so silly because I cannot tell with any certainty which rule I should follow when!?
Homework Statement
Data for Question B:
(initial)[CH3COOH] = 0.500 mol dm–3 and) eqm [CH3COOH] = 0.200 mol dm–3;

Question A) " FInd the pH of a mixture of 50.0 cm3 of 0.100 mol...
Sorry, before I go ahead, Is the reaction reversible? I seem to have made a stupid assumption that I can talk about the equilibrium shifting to remove excess reactants when it mayn't be a reversible reaction. How do I know if it is one? THanks Borek
Hi So the reaction is below:
Sodium thiosulfate + HCl = Sulfur + NaCl+ Water+ SO2
So if I wanted to say 'Increasing the conc. of Sodium thiosulfate has shifted the equilibrium to the left (reactants) and thus the system works to break down excess reactants and create more product by...
Talk about luck haha! My mum's been teaching german for 15 years, however, A complexing agent I did come across was zincon, which was holy costly! Yes, so sorry for the late up date. But I'm going with AAS since I can't find a complexing agent other than zincon for zinc.
Sorry, that's beyond me! :O I'm just a 17 year old guy! Please sympathize with me, this is tough enough with so much chemistry that's waay about my level!
Urgent: Some complexing agents for zinc.
Hi, I am to extract Zinc from plant tissue, with 0.1N HCl. But since its colorless I cannot determine the concentration(using the colorimeter) of zinc without adding a chemical that forms a complex with zinc and has a color.
How would you extract zinc from a plant?
Hi!
So I basically need to find out how I'm supposed to extract zinc from a plant and its methodology and chemicals required. How do I do this? I found one article that is rather incomplete, it just says zinc was extracted using 0.1N HCl and not...
Well, turns out I won't need to flip the sign. However I have hardly varied my independant variable hence I must perform the experiment with 0.025 M, 0.05M, 0.1M, 0.2M, 0.4M masses of the chemicals. That will indicate efficiency in a better manner, you know may be I could calculate the average...
Woops! ignore my ignorance, I was just told that, well doesn't the AAS give you the concentration directly? Gosh, just pointless maches *argh*
CHANGE: AAS or COLORIMETER
