B The balanced chemical equation is Li 2 O(s) + H 2 O(l) → 2LiOH(aq). A Potassium is a reductant, whereas methanol is both a weak acid and a weak base (similar to water). A weak acid produces H + , which can act as an oxidant by accepting an electron to form 1/2 H 2 This reaction, therefore, is an acid dissociation that is driven to completion by a reduction of the protons as they are released.

How Potassium Reacts With Iodine | Healthfully
Because many chemical reactions result in the formation of a chemical bond, it''s common to assume that when potassium reacts with iodine, the resulting compound--potassium iodide--is held together by a chemical bond. In fact, this is not so, notes Silberberg.

CHEMISTRY WORKSHEET ____NAME
You do not have a chemical equation until it is balanced. Balancing is done by inserting coefficients for the terms in the equation; you never balance an equation by changing subscripts.. Many chemical reactions fit into one of four general classes: composition (or synthesis), decomposition (or analysis), single replacement (or simple replacement), and double replacement (or metathetical).
Ionic compound - Wikipedia
In 1913 the crystal structure of sodium chloride was determined by William Henry Bragg and William Lawrence Bragg. This revealed that there were six equidistant nearest-neighbours for each atom, demonstrating that the constituents were not arranged in molecules or finite aggregates, but instead as a network with long-range crystalline order.
