10th Grade Honors Chemistry

The Particle Level and Our Everyday World

The quantum mechanical model of the atom is our current understanding of the structure of the atom.

The properties of a substance are influenced by its molecular shape, polarity and intermolecular attractions.

The number of atoms and types of atoms are conserved in a chemical reaction. Chemical reactions are the rearrangement of those atoms to form new substances and are accompanied by a change in the potential energy of the system.

Measurements always contain some level of uncertainty. Dimensional Analysis is a technique used to convert between units in chemistry.

The mole is used as a bridge for determining quantities in chemical reactions.The quantity of a substance in a chemical reaction can be predicted using stoichiometric principles.

The collision model helps to explain how a reaction occurs and how a number of factors (surface area, concentration, temperature, use of a catalyst, etc.) can influence the rate of a chemical reaction. Potential energy diagrams can also be used to show the progress of a reaction. 

The pH scale is a measure of how acidic or alkaline a solution can be. Acids and bases can react with each other by transferring a positive hydrogen ion between them
