Describe the attractions of molecules that occur during intermolecular interactions.

2. provide desriptions and examples of each of the interactions below:

ionic-

hydrogen bonds-

dipole-

van der waals-

is there multiple choice answers?

1. for the first question, we must find the mass of the anhydrous salt, mgso₄. the molar mass for mgso₄·7h₂o is 246.47 g/mol, while that of mgso₄ is 120.37 g/mol.7.834 g mgso₄·7h₂o * 1 mol mgso₄·7h₂o/246.47 g * 1 mol mgso₄/1 mol mgso₄·7h₂o * 20.37 g mgso₄/mol = 0.647 g mgso₄

2. mass of water = mass of sample - mass of anhydrous salemass of water = 7.834 - 0.647 = 7.19 gpercent water in hydrate = 7.19/7.834 * 100 = 91.74%

a compound is a molecule made of atoms from different elements.

a. by the combination of an unlimited number of elements

i think the answer is terrae but not 100 percent sure. ▓▬▬ §
