I'm wondering if anyone else here has had strange reactions to certain drugs or has known anyone who has.

I've had very strange reactions to ECP heroin. I can't say it doesn't do anything, but it doesn't do what it's supposed to do. Instead of feeling a rush, my heart speeds up and pounds really hard, then when my heart goes back to normal, I feel nothing. About 45 minutes or so later, I might feel a little something, but not really a high or any pain relief. My eyes don't even get pinned. I'

100 mL is exactly Neutralized by 150 mL of 0.1M Ca(OH)2 


answer is 0.1 M H3PO4

How is this supposed to be done?

So I have absolutely no clue how to do this so if you could please help answer with explanations it would be VERY much appreciated.


There are 4 beakers all reacted with Potassium Permanganate and I need to write an equation describing the reaction in each beaker...
(It's not specified whether it needs to be symbol or word though) 

Beaker 1-
1cm^3 of sodium thiosulfate

I have a couple of redox reactions i just can't wrap my head around.


SO2 + Br2 :rarrow: HSO4- + Br-

S on the left side has oxidation number +4 and on the right side +6. Br has the oxidation number 0 but reduces to -1. However, if i increase SO2 to get the desired O4 required on the right side i'm still left with an Extra S. Is it possible to equalize on the left side with H3O+ or is there some other way?

[size=medium]Cr2O72-

[size=medium]I have conducted a series of reactions between ethyl-3,4-dihydroxybenzoate and 2-(2-chloroethoxy)ethanol in MeCN where I varied the base, I tried Li2CO3, Na2CO3, K2CO3, LiOH, NaOH, KOH, NEt3. the only reaction that produces any yield after 7 days of reaction was K2CO3 (30%) I have since increased this to 83% (including some KI, Finkelstein reaction). I do not fully quite understand why only K2CO3 gave product. I think it may be because Li+ and Na+ are quite hard cations and coordina

Dear all, 

   I have several issues regarding the organic chemistry. 
  First of all is 1H-phenalene aromatic? why?
  My second question is related to esterification. Is it possible to obtain an ester from an organic acid and R-OTs? how is it working?

Hi, 


What reaction do you get when putting the following products together?

Dodecylbenzene (C12H25C6H5) with sodium hydroxide (NaOH)= no reaction?
Fatty alcohol (C12-16) with sodium hydroxide = Fatty alcohol salt?
Monoétanolamine (C2H7NO) with sodium hydroxide = reaction?
Ammonia solution with sodium hydoxide = NH3 (gas) with water?
[size=medium]Fatty acid with sodi

What needs to be considered when balancing oxidation-reduction reactions that does not need to be accounted for when balancing a standard formation reaction, such as 2H2 _ O2  :rarrow: 2H2O?


I'm not sure how these are related, but I'm assuming that the "thing to be considered" is charge?

Hi, 


I have to write the equations for the three redox reactions in the oxidation state of vanadium. 

I started by writing the half reactions, and I wonder if they're correct?

V2+ → V3+ 
VO2+ → V3+ + H2O 
VO2+ + 2H+ → V3+ + H2O 
VO2+ + 2H+ + e- → V3+ + H2O 

Thanks in advance
