I am studying for my exams. I found some concepts that are confusing me! Can somebody help me? I would appreciate! Quantum
1. Why "matter and energy are not distinct...energy is a form of matter"?Structure and properties of solids
2.What is a crystal lattice?
3. (i) and (ii) are from my text book, they seem to contradict each other. I don't know which INTERMOLECULAR force is stronger...ionic or network covalent?
(i)"In general, ionic bonding is much stronger than all intermolecular forces"
Covalent network crystals:
(ii)"the overall bonding in the large marcromolecule of a covalent network is very strong -- stronger than most ionic bonding and intermolecular bonding"
4.Is it true that ionic compounds generally have high solubility in water, and molecular compounds generally have low solubility in water?
