Pre-Algebra on Khan Academy: No way, this isn't your run of the mill arithmetic. This is Pre-algebra. You're about to play with the professionals. Think of pre-algebra as a runway. You're the airplane and algebra is your sunny vacation destination. Without the runway you're not going anywhere. Seriously, the foundation for all higher mathematics is laid with many of the concepts that we will introduce to you here: negative numbers, absolute value, factors, multiples, decimals, and fractions to name a few. So buckle up and move your seat into the upright position. We're about to take off!

The periodic table is organized by grouping elements with similar chemical properties and electron structures. An element's location on the table can be used to determine its electron configuration. By following the order of periods (rows) and blocks (s, p, d, f), you can trace how electrons fill the atom's orbitals and efficiently determine the distribution of electrons in an atom.

Molecular polarity is determined not just by individual polar bonds, but by the molecule’s 3D shape. Even if bonds are polar, the overall molecule may be nonpolar if the shape cancels out the dipoles. Whether a molecule is polar or not influences properties like solubility, boiling points, and intermolecular interactions.

Practice converting from grams to moles to molecules, formula units, and atoms through these four example problems. Grams are the standard unit of mass in the laboratory, while moles are used in calculations to relate mass to the number of particles. This system of units allows for communication between the microscopic world of atoms and the macroscopic world we interact with daily.

Atomic mass units (a.m.u.) are much smaller than grams and are used to measure atomic-scale masses. Avogadro's number (6.022 x 10²³) represents the quantity of particles in one mole, linking atomic masses to measurable amounts in grams. Molar mass, expressed in grams per mole, bridges these concepts, enabling the conversion between the mass of a substance and the amount in moles.

Double replacement reactions occur when two compounds exchange ions, forming two new compounds. The driving force in these reactions is often the formation of a precipitate, a gas, or water. A solubility chart is commonly used to predict whether a potential product will be insoluble and therefore precipitate out of solution. This allows us to determine if the reaction will actually occur.
Sections: 00:00 - Experimenting with aqueous NaCl and AgNO3 01:13 - Visual explanation of a double replacement reaction 03:13 - Are double replacement reactions also redox reactions? 04:21 - Driving force in double replacement reactions - precipitation 05:42 - General form of double displacement reactions 06:25 - Understanding a solubility chart 07:34 - Using a solubility chart 10:35 - Acid base neutralizations

When one element replaces another element in a compound, we call it a single replacement reaction. In these reactions, one atom loses electrons (oxidation) while another element gains those electrons (reduction), making them a form of a redox reaction. Learn to use the Activity Series, which ranks elements by their reactivity and helps predict if the reaction will occur.
