Stoichiometry and Redox (Digital Notes)
$150.00 Add to cartStoichiometry of redox reactions means calculations of the quantities of the oxidizing and reducing agents and their products in oxidation reduction reactions. Redox, on the other hand, is a type of chemical reaction in which the oxidation states of substrate change. Oxidation is the loss of electrons or an increase in the oxidation state, likewise, reduction is the gain of electrons or a decrease in the oxidation state.

Gibbs Free Energy (Digital Notes)
Read moreGibbs free energy, denoted G, combines enthalpy and entropy into a single value. The change in free energy, ΔG, is equal to the sum of the enthalpy plus the product of the temperature and entropy of the system. ΔG can predict the direction of the chemical reaction under two conditions: 1. constant temperature and 2. constant pressure.

The Gaseous State (Digital Notes)
$100.00 Add to cartThe gaseous state of matter occurs between the liquid and plasma states, the latter of which provides the upper temperature boundary for gases. Bounding the lower end of the temperature scale lie degenerative quantum gases which are gaining increasing attention. High-density atomic gases super-cooled to very low temperatures are classified by their statistical behavior as either Bose gases or Fermi gases.

The Periodic Table (Digital Notes)
$100.00 Add to cartThe periodic table, also known as the periodic table of the (chemical) elements, is a rows and columns arrangement of the chemical elements. It is widely used in chemistry, physics, and other sciences, and is generally seen as an icon of chemistry. It is a graphic formulation of the periodic law, which states that the properties of the chemical elements exhibit an approximate periodic dependence on their atomic numbers.
