Chapter 5 - Ionic Bonding

Chapter 5 - Ionic Bonding. Bonds. Chemical bond - forces of attraction that hold atoms together. The molecule is more stable than the separate ions/ atoms. Bond energy - the energy required to break (or form) a chemical bond. Energy is released when the bond is formed.

Equilibrium

Equilibrium. Reactions are reversible. A + B C + D ( forward) C + D A + B (reverse) Initially there is only A and B so only the forward reaction is possible As C and D build up, the reverse reaction speeds up while the forward reaction slows down. Eventually the rates are equal.

III. Moles/Stoichiometry

III. Moles/Stoichiometry. In all chemical reactions there is a conservation of mass, energy, and charge. Matter cannot be created nor destroyed, only changed from one form to another Energy cannot be created nor destroyed, only changed from one form to another.
