Answer: ammonium bromide : acidic : The pH will be less than 7.
potassium cyanide : basic :The pH will be more than 7.
calcium nitrate: neutral : The pH will be approximately equal to 7.
calcium hypochlorite : basic :The pH will be more than 7.
Explanation:
pH is defined as the negative logarithm of hydrogen ion concentration. The scale ranges from 0 to 14.
When a solution is acidic, it will show a pH in the range of 0 - 6.9. When a solution is basic, it will show a pH in the range of 7.1 - 14. When a solution is neutral, it will show a pH of 7.
ammonium bromide : 
: acidic as it is formed from the combination of strong acid HBr and weak base 
potassium cyanide :
: basic, as it is formed from the combination of weak acid HCN and strong base KOH
calcium nitrate: 
: neutral, as it is formed from the combination of strong acid and strong base.
calcium hypochlorite : 
: basic, as it is formed from the combination of weak acid 
and strong base 
Answer:
Strong attraction between ions and the second one High melting points
Explanation:
Because they are more in close proximity to the core atom's nucleus than lone pairs are, lone pairs reject other lone pairs more strongly than bonding pairs do effect the bond angle.
When a single pair of electrons at the central atom begins to resist the bound pair of electrons, the bond angle decreases and the bonds are slightly shifted inward. It moves existing atoms closer together and modifies their geometry. It's equivalent to include an atom. When there is an increase in back bonding, the bond angle rises. Because the lone pair electrons of the two atoms reject one another, adjacent atoms in a molecule that have lone pair electrons will not be kept together in their bond as securely.
