Ah found it, so i got quite stuck on this too, so basically adding 10ml of solvent x dilutes the concentration of I2 in the solution. So to increase the Concentration again, the Eq shifts to favour the forward reaction, decreasing the conc of I2 in Y
Question if needed
Define the following
P = 1 X 2 X 3 X ... n
S = 1 + 2 + 3 ... n
Show that if n is odd, then P is divisible by S.
I said that P was n! and S was n(n+1)/2 and then let n = 2k + 1 and then divided the two to get what they have in the answers
Hi all, this might seem really simple, but I was just reading through the solution to this paper, I wasn't sure why k +1 is a factor of (2k + 1)! i understand 2k because of the 'unrolling' of the factorial
because now the H+ ions aren't reacting with anything because all the OH- have been reacted so the equation is not shifted to the right anymore, the benzoic acid is left in equilibrium and you have to use the ICE table to find how much H+ has really dissociated from the weak acid
hope your...
You dont have to take into account the weak acid equilibrium because it doesn't really matter for the neutralisation reaction. Take acetic acid and NaOH for example. When they react, you wouldn't write the equation with a reversible arrow because it isn't really reversible. This is because the...
I think they've calculated the moles of Benzoic acid first to find the limiting reagent because as you can see in the reaction they've given, although NaOH and Benzoic acid react in a 1 to 1 ratio, there are excess Benzoic acid moles, which means whilst the rest will be neutralised, the pH will...
As per @graceluvsA's kind and intelligent suggestions I have tried to use their suggestion of a palimpsest metaphor. Let me know if it is too on the nose. Otherwise, if the stimulus is a more picture/object kind of quote, I will use that as the motif but if it more a craft of writing stimulus, i...
