It details the calculation of molar solubility via solubility product constants (Ksp), including the creation of an ICE table to find ion concentrations and deriving molar solubility. The final conversion from molar solubility to solubility is also addressed.

The naming convention is similar to binary compounds, with the cation mentioned first. It also describes the use of parentheses for multiple polyatomic ions and the importance of charge balance when writing formulas. Notably, it emphasizes unique behaviors of specific polyatomic ions like dimercury and peroxide.

It is a group 2 metal, also known as an alkaline-earth metal, and no populated d-orbital electrons. Calcium is the fifth most abundant element by mass (3.4%) in both the Earth's crust and in seawater. All living organisms (in fact, even dead ones) have and need calcium for survival.

It defines a decomposition reaction as the breakdown of a compound into simpler substances, needing energy input. Examples include the transformation of mercury(II) oxide into mercury and oxygen, and calcium carbonate into calcium oxide and carbon dioxide. It also mentions that various compounds can decompose through methods like heat or electric current.

It covers equilibrium concepts, stating that at equilibrium, the free energy change (ΔG) is zero, and the equilibrium constant (Keq) indicates product or reactant favorability. The page includes examples of calculating Keq from ΔG∘ and vice versa using thermodynamic equations.
