Ba(OH)2 +HCL---> BaCl2 + 2H2O
what does gradient show on feasanility graph
- delta S
what does Y interceot show
delta H
what does x axis show
point wt which resction is fewsbile
when wont concentrwtion chnage for PH
if Ha/A- is the same
if metal is added how do you work out PH
1) work out moles of metal
2)HA moles - metal moles
3) A- moles + metal moles
4) new concentrwtion
enthalpy change of atomisation
the enthslpy chsnge when one mole of a solid ionic compound is formed from its gaseous ions under standard conditioms
lattice enthslpy
the enthslpy change that is associated with the formation of one mole of an ionic compound from its gaseous ions under standard conditioms
what do you dip your salt bridge into
KNO3
enthslpy change of hydratiom
the enthslpy chnage when 1 mole of gaseous ioms dissolve in water
average bond enthalpy
breaking of 1 mole of bonds in gaseous molecules
how do i work out y intercept
e^number
what happjes to kc if o2 increaxes in o2 + s--> 3SO3
1)O2 comc incresses
2) denominator in Kc expression increases
3) so yield of so3 increases and numerator increases
s +o2--> 3So3 ahat happnes if oressure increases
1) equlibriuk shifts to right
2) ratio in Kp exression decreases so ratio in kp expressiom imcreases to restore Kp
what happnes to kp if sjofts to right with pressure
1) rwtio of kc expression decreases
2) ratio of kc expression imcreases to restore kp
what happmes to kp if it shfts to left with pressure
1) ratio within kc espression increases
2) ratio within kc expression decreases to restore kp
what happmes if eq shiftd to left with conc
1) denominator within kp expression will increwse
2) so mire of thwt will yield amd numerwtor within kp expression will decrease to restore kp
what happnes to ph as you move down group 2
increases
how does hameoglobin transport oxygen sroumd body
o2 coordinatley bonds to fe2+. when required o2 released amd replaced by h20
whst does it mean if kp> 1
equilibirum position lies far on the right
