what is electronegativity gap
The greater the difference in the electronegativity the more polar the bond is

what is electronegativity gap
why are u comparing SE with O and S with O why not SE with S this would easier for me to understand why complicateThe greater the difference in the electronegativity the more polar the bond is
SE and S both are bonded to O . You consider the the electronegativity difference between both the cases.why are u comparing SE with O and S with O why not SE with S this would easier for me to understand why complicate

Can you answer this also please? Its from the same year and variant is 13.
As HSO3 -1 is conjugated base of SO2 what's the answer?
can someone explain me x ray crystallography
As HSO3 -1 is conjugated base of SO2 what's the answer?
Equilibrium constant does not change when you change the pressure of a system. The only factor that affects the equilibrium constant is temperature.Can anyone explain to me why change in pressure won't affect equilibrium constant?
Have u tried chemguide??

nitrogen is been reduced because see the oxidation number of nitrogen in NCl3 nitrogen oxidation number is +3 and nitrogen oxidation number in N2 is 0 therefore nitrogen has gained electrons and we know that gaining electrons is reductionAnd can anyone on Earth tell me what am I missing in this question?
The refrence is 9701/12/M/J/11 [ U can check the markscheme, the answer is A. How is 1 correct ?!!!

check out the ionisation energy values the element which has the highest value .. so d is the answer because Na+ has the highest valueO/N 11/12 question 3
Can anyone who is good in chemistry solve this?
Use of the Data Booklet is relevant to this question.
From which particle is the removal of an electron the most difficult?
A Cl- (g) B F- (g) C K+ (g) D Na+ (g)
The reaction of hydrogen sulphide with sulfur dioxide gives sulphur as one of the products. h
H2S(aq) < -------> 2H2+(aq) +2e+S(s)
SO2(aq)+ 4H2+4e< -------> S(s) +H2O
how many moles of hydrogen sulphide are neede to react with sulphur dioxide to produce 1mole of sulphur ?
Help?
a- 1/3 mol
b-2/3 mol
c-3/2 mol
d-2 mol
8 (a) Electrophoresis can be used to separate amino acids which are produced by the
hydrolysis of a polypeptide.
Using glycine as an example, explain why the result of electrophoresis depends on pH.
