Thermostoichiometry

It was French scientist Antoine Lavoisier that introduced the Law of Conservation of Matter. This law states that matter can be neither created nor destroyed. A chemical reaction that starts with twenty grams of reactants will produce twenty grams of products. You learned that stoichiometry refers to the relative quantities of elements in a molecule, or the relative amounts of reactants and products in a chemical reaction. Stoichiometry, in its simplest definition, merely refers to the relative proportion of components. In this topic, you will investigate thermostoichiometry. Thermostoichiometry refers to the relative proportion of components in a reaction om which energy and heat are associated.

Essential Question
