Can someone please explain the ideal gas equation? It is making no sense to me.

It means draw curve at once, no sharp edges at curve, no repetitionWhats a smooth curve ?
What you mean by no repetition ?It means draw curve at once, no sharp edges at curve, no repetition
What you mean by no repetition ?
do we join points by scale ?
Still As level kid here.In on2006 paper 4
can some one tell me why they chose ph to be the pka ?
But i didnt ask uStill As level kid here.
someone, includes meBut i didnt ask u
For the phosphorus iodine, does iodine always replace OH in a reaction, or just for that alcohol the one that they gave?well about how should we know this, they are all general equations and you sort of have to remember them!
with phosphorus and iodine, there will be replacement of OH by I
with conc. H2SO4, there will be elimination of water, for that we will take the -OH group from one carbon and the -H from the carbon right next to it, and it will form an alkene
with hot K2Cr2O7, the double bond will dissolve (if any) and the -OH will be oxidised to -COOH, but not in tertiary alcohols!, they wont react!
c(iii) th gas in (ii) is CO2 and if you see total of gas formed is 40 but only 30 remains when the tottal gas is shaken with KOH(aq) se where did the 10 go it reacted with Koh(aq) and the gas is CO2 so 10cm^3
Can someone please help me with bond angles? AB2/AB3 systems etc I've got absolutely no clue what it is. asma tareen
By adding water ._.paper5 :
how you would measure the independent variable ( concentration of HCl )
markscheme says : "Dilutes a range of volumes of HCl" how ?
I could too say that.By adding water ._.
