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.

They are present in total ionic equations to balance the charges of the ions. Whereas the Cu 2+ and CO 2− 3 ions combine to form a precipitate of solid CuCO 3. In reaction stoichiometry, spectator ions are removed from a complete ionic equation to form a net ionic equation. For the above example this yields:
A classic example is when water molecules arrange around a metal ion. If the metal ion is a cation, the electronegative oxygen atom of the water molecule would be attracted electrostatically to the positive charge on the metal ion. The result is a solvation shell of water molecules that surround the ion.
The structure of part of a DNA double helix Hydrogen bonding between guanine and cytosine, one of two types of base pairs in DNA. In these macromolecules, bonding between parts of the same macromolecule cause it to fold into a specific shape, which helps determine the molecule's physiological or biochemical role.
Ionic bonding is a type of chemical bonding that involves the electrostatic attraction between oppositely charged ions, or between two atoms with sharply different electronegativities, [1] and is the primary interaction occurring in ionic compounds. It is one of the main types of bonding, along with covalent bonding and metallic bonding. Ions ...
An example of active transport of ions is the Na +-K +-ATPase (NKA). NKA is powered by the hydrolysis of ATP into ADP and an inorganic phosphate; for every molecule of ATP hydrolized, three Na + are transported outside and two K + are transported inside the cell.
The Bromley equation [11] has also been compared to both SIT and Pitzer equations. [12] It has been shown that the SIT equation is a practical simplification of a more complicated hypothesis, [ 13 ] that is rigorously applicable only at trace concentrations of reactant and product species immersed in a surrounding electrolyte medium.
