a very dilute orange juice flows along a smooth tube (0.010m in diameter) with a maximum flow rate of 0.1m/s.
a) State the assumptions needed to solve the problem
b) Calculate the pressure gradient
Equations:
Vmax = (Change in P * R^2)/(4*viscosity*L)
Reynolds number = (density*D*v)/viscosity...
EDIT: the ratio in the absorbing solution is 5.2:1 I made a mistake
So what i would like to know is why the excess 0-phenanthroline in the absorbing solution?
[b]1. This is a question about a lab.
The absorbing solution used in the lab had a mole ratio of phen to Fe of 52.8:1
However, the complex [Fe(phen)3]2+ has a mole ratio of 3:1 for phen:Fe
[Fe(phen)3]2+ is a coloured complex and we were determing iron concentration in a tablet.
I don't...
for the equilibrium part is it ok to say that Q doesn't equal K initially therefore reaction isn't at equilibrium. q is less than K therefore reaction moves towards products
Also I need to calculate the volume of this suspension required to prepare 100mL of 25ppm(w/v) solution of amoxicillin trihydrate. assume desnity of suspension = 1kgL-1
I'm not sure if what I have done is right:
to get 25ppm I ned 2.5x10-5g/L solute
Conc. of 5mL suspension = 120g/L
Volume...
1. Augmentin ES is a powder containing amoxicillin tri hydrate and potassium clavulanate for oral suspension. Each 5mL of reconstituted aqueous oral suspension contains 600mg of amoxicillin trihydrate and 7.07mg of potassium.
Calculate the mass of potassium clavulanate in 5mL of the oral...
I am still not sure how to show the conc. of Cl- in terms of x. Can you show the conc. of Co(h20)62+ as 0.182-x?
And I know that intially Q doesn't equal K but how can I show this?
I am totally confused with this question and have trying to figure it out for hours!
Co(H2O)6[SIZE="1"]2+ (aq) + 4 Cl- (aq) ----> CoCl4[SIZE="1"]2- (aq) + 6 H2O (l)
The equilibrium constant K = 4.82x 10-4
We begin by putting enough [Co(H2O)6]Cl2 (assume the salt dissociate completely into...
