34*Any guess paper or prediction for tomorrow practical chemistry P33?
please email me if you find something - [email protected]
please can any one tell about the ions of p34
i think sulphate,copper and iron 2please can any one tell about the ions of p34
Thermometer to whole number like 50.0 or to .5 like 64.5Can Anyone Tell what's the accuracy of Burette ,pippete ,meauring cylinder and Thermometer? (how many d.p would i write if i measure from each one of these?)
What type of pipette? 25?Uncertainty in pipette is 0.06?
Practice. I don't think it's right to ask this since the admin of Xtremepapers check the forums and ban people for discussing such questions. Good tip: memorize cation and anion rxns or at least learn to identify what the question is asking so you don't have to waste time going through the last sheet.
yesWhat type of pipette? 25?
In 28 A, an intermediate is formed with O- and so the reaction is a 2 step processView attachment 63722 View attachment 63723 Need help with this.
For the first one i know its a reaction pathway of SN1 reaction but why can it not be A or D since they don't have graphs like that i guess
For 32, O has 2 unpaired p electrons and for the Cl+, u need to understand that Cl atom has 5 p electrons, 2 paired and 1 unpaired...when Cl+ is formed, the electron removed is from the full p orbital, leaving 2 unpaired p electrons behindView attachment 63722 View attachment 63723 Need help with this.

Thankssss4 B .... in Al2Cl6 1 Al atom has 4 bonds thus 8 electrons .....In CH3+ = 4 electron of carbon naturally 3 electron given by H -1 due to + chage so 4+3-1 = 6 ....In Cl2O ..(just like H20) oxygen in g6 + 2 bonded electrons = 8 ....In H2ClC. C radical (1 electron un paired) means carbon is bonded to 3 atoms and C-Cl means Cl has 8 ....
