The epistropheus apparently bore two hypapophyses, as in Varanus; the posterior one lay relatively far forward. The eighth, ninth and tenth vertebrae differ somewhat from the preceding ones by their breadth. Instead of rectangular outlines they show a more square shape. Also these three vertebrae are provided with needle-shaped cervical ribs.
In chemistry, neutralization (US spelling) or neutralisation (UK spelling), is a chemical reaction in which an acid and a base react quantitatively with each other.In a reaction in water, neutralization results in there being no excess of hydrogen or hydroxide ions present in solution.n a titration of an acid with a base, the point of neutralization can also be called the equivalence point. The quantitative nature of the neutralization reaction is most conveniently expressed in terms of the concentrations of acid and alkali.
When a double displacement reaction occurs, the cations and anions switch partners, resulting in the formation of water and a new ionic compound (or salt), which is usually soluble. Neutralization reactions are exothermic, and are generally accompanied by a noticeable release of heat.n these reactions one of the products (AD or CB) after the double displacement is in the gaseous state, such as hydrogen sulfide (H2S) or ammonia (NH3). One of the products could also be carbonic acid (H2CO3) or sulfurous acid (H2SO3).
