Choose the Ksp expressions for the following reactions. Ca3(PO4)2(s) 3Ca+2 (aq) + 2PO4 -3(aq)

Ksp = [Ca+2]2[PO4-3] 2
Ksp = [Ca+2]3[PO4-3] 3
Ksp = [Ca+2]3[PO4-3] 2
Ksp = [Ca+2]2[PO4-3] 3

Consider the directing effects of the substituents on salicylamide and predict the possible structures of the iodination products. which do you think will be the major product?

Covalent bonds generally form when the bonded elements have a difference in electronegativity less than 1.5. subtract the electronegativities for the following pairs of elements and predict whether they form a covalent bond. electronegativity difference of c and c: ionic covalent electronegativity difference of mg and cl: ionic covalent
