Remember: energy is conserved in a chemical reaction (visualize the reaction and question whether heat lies on reactant side (left) or product side (right))

-exothermic- heat is released (heat is on the product side)

>forming an ionic lattice (SALT)- mixture of Na and Cl results in a more stable ionic lattice, causing this reaction to be exothermic

>burning wood

-endothermic- heat is absorbed (heat is on the reactant side)

> cooking an egg
