Using clear labelled dot-cross diagrams explain how the following atoms bond together: (i) potassium and fluorine in potassium fluoride, (KF)
(ii) hydrogen and oxygen in water, (H2O)
(iii) fluorine and boron in boron trifluoride, (BF3)

The conventional equilibrium constant expression (kc) for the system below is: 2icl(s) ⇄ i2(s) + cl2(g) [cl2] ([i2] + [cl2])/2[icl] [i2][cl2]/[icl]2 none of the listed answers are correct [i2][cl2]/2[icl]
