1. TABLE I – HEAT OF REACTION
THESE REACTIONS ARE COMBUSTIONS; O2 (AND A FUEL) ARE REACTANTS AND CO2 AND H2O ARE PRODUCTS
O2 IS A REACTANT
CO2 IS A PRODUCT
H2O IS A PRODUCT
∆H IS ALWAYS -, EXOTHERMIC

2. TABLE I – HEAT OF REACTION
SYNTHESIS REACTIONS: SMALL SPECIES COMBINE TO FORM LARGER ONE(S).
THESE REACTIONS ARE EXOTHERMIC (∆H = - ), PRODUCTS HAVE LESS ENERGY THAN THE REACTANTS AND ARE MORE STABLE.

3. TABLE I – HEAT OF REACTION
SYNTHESIS REACTIONS: SMALL SPECIES COMBINE TO FORM LARGER ONE(S).
THESE REACTIONS ARE ENDOTHERMIC (∆H = + ), PRODUCTS HAVE MORE ENERGY THAN THE REACTANTS AND ARE LESS STABLE.

4. TABLE I – HEAT OF REACTION
SYNTHESIS REACTIONS: SMALL SPECIES COMBINE TO FORM LARGER ONE(S).
ENDOTHERMIC
EXOTHERMIC
THESE REACTIONS ARE FORMATION REACTIONS, COMPOUNDS FORMED FROM ELEMENTAL STATE GAS ELEMENTS. HEAT OF FORMATION (∆HF)IS EVOLVED OR RELEASED.

5. TABLE I – HEAT OF REACTION
IONIZATION REACTIONS: ELECTROLYTES RELEASE COMPONENT IONS INTO SOLUTION.
BASE IONIZATION, RELEASES OH- AS ONLY NEGATIVE ION.
SALT

SALT
NEUTRALIZATION
THESE REACTIONS ARE SALT IONIZATIONS THAT OCCUR WHEN WATER IS ABLE TO FORM MOLECULE TO ION ATTRACTIONS WITH THE IONS, THUS REMOVING THEM FROM THE CRYSTAL (DISSOLVING).
