Chemical Reactions

Simple Chemical Reactions
Construct and revise an explanation for the outcome of a simple chemical reaction based on the outermost electron states of atoms, trends in the periodic table, and knowledge of the patterns of chemical properties.

Total Bond Energy Change in Chemical Reactions
Develop a model to illustrate that the release or absorption of energy from a chemical reaction system depends upon the changes in total bond energy.

Collision Theory and Rates of Reaction
Apply scientific principles and evidence to provide an explanation about the effects of changing the temperature or concentration of the reacting particles on the rate at which a reaction occurs.

Increased Products Design Solution
Refine the design of a chemical system by specifying a change in conditions that would produce increased amounts of products at equilibrium.

Conservation of Atoms in Chemical Reactions
Use mathematical representations to support the claim that atoms, and therefore mass, are conserved during a chemical reaction.
