i'm so lost now :S

2.70 then .

That's interesting. I normally do pH to 1 or 2 decimal places :S

n (HCl) = C * V n (HCl) = 0.08 * 0.02 n (HCl) = 1.6*10^-3mols n (NaOH) = C * V n (NaOH) = 0.05 * 0.03 n (NaOH) = 1.5*10^-3mols n (excess) = n (HCl) - n (NaOH) n (excess) = 1.6*10^-3 - 1.5*10^-3 n (excess) = 1*10^-4 mols of HCl C = n / V C = 1*10^-4 / 0.05 C = 2*10^-3mols pH = - log [H+] pH =...

I've never seen a thread about cheating in the HSC :S

Both glucose and ethanol are aqueous in fermentation.

Refer to question, if the question shows numbers with 2 sig fig then use 2 sig fig etc etc .

hai a/s/l ? yu know who i am now :D ?

to, lo, mo are the rest frame.

ohh . sigh =w=

Scaling is the build up of Calcium Carbonate.

Anode: Zn(s) -> Zn2+ + 2e- Cathode: 2MnO2(s) + 2NH4+(aq) + 2e- -> Mn2O3(s) + H2O(l) + 2NH3(aq)

Chemical Equations are always in the marking guidelines so you must include them.

gg LOL T_T;;
