2. Van Arkel–Ketelaar triangle - Wikipedia

   en.wikipedia.org/wiki/Van_Arkel–Ketelaar_triangle

   Example is here. On the right side (from ionic to covalent) should be compounds with varying difference in electronegativity. The compounds with equal electronegativity, such as Cl 2 are placed in the covalent corner, while the ionic corner has compounds with large electronegativity difference, such as NaCl (table salt). The bottom side (from ...

3. Chemical equation - Wikipedia

   en.wikipedia.org/wiki/Chemical_equation

   A chemical equation is the symbolic representation of a chemical reaction in the form of symbols and chemical formulas.The reactant entities are given on the left-hand side and the product entities are on the right-hand side with a plus sign between the entities in both the reactants and the products, and an arrow that points towards the products to show the direction of the reaction. [1]

4. Product (chemistry) - Wikipedia

   en.wikipedia.org/wiki/Product_(chemistry)

   Much of chemistry research is focused on the synthesis and characterization of beneficial products, as well as the detection and removal of undesirable products. Synthetic chemists can be subdivided into research chemists who design new chemicals and pioneer new methods for synthesizing chemicals, as well as process chemists who scale up chemical production and make it safer, more ...

5. Structural formula - Wikipedia

   en.wikipedia.org/wiki/Structural_formula

   Skeletal structural formula of Vitamin B 12. Many organic molecules are too complicated to be specified by a molecular formula. The structural formula of a chemical compound is a graphic representation of the molecular structure (determined by structural chemistry methods), showing how the atoms are connected to one another.

6. 1/3–2/3 conjecture - Wikipedia

   en.wikipedia.org/wiki/1/3–2/3_conjecture

   Therefore, the pair of a and c have the desired property, showing that this partial order obeys the 1/3–2/3 conjecture. This example shows that the constants 1/3 and 2/3 in the conjecture are tight; if q is any fraction strictly between 1/3 and 2/3, then there would not exist a pair x, y in which x is earlier than y in a number of partial ...

8. RICE chart - Wikipedia

   en.wikipedia.org/wiki/RICE_chart

   For example, if the reaction equation had 2 H + ions in the product, then the "change" for that cell would be "2x" The fourth row, labeled E, is the sum of the first two rows and shows the final concentrations of each species at equilibrium. It can be seen from the table that, at equilibrium, [H +] = x.

9. Chemical decomposition - Wikipedia

   en.wikipedia.org/wiki/Chemical_decomposition

   H 2 CO 3 → H 2 O + CO 2. Other carbonates will decompose when heated to produce their corresponding metal oxide and carbon dioxide. [5] The following equation is an example, where M represents the given metal: MCO 3 → MO + CO 2. A specific example is that involving calcium carbonate: CaCO 3 → CaO + CO 2. Metal chlorates also decompose ...
