Describes shape and location of fish fins, but not how each fin type helps a fish move through water, for example, a tail fin acts as rudder and propeller. Canât describe shape or location of fish fins or how each fin type helps a fish move through water.elvic fins, located on the bottom of the fish in front of the anal fin, help balance the fish, keep it level, and prevent it from rolling from side to side. Fish sometimes rest by sitting on their pelvic fins.
The oxidation number of lithium in lithium nitrate is 1. Formula: LiNO3. Hill system formula: Li1N1O3. CAS registry number: [7790-69-4] Formula weight: 68.946. Class: nitrate. Colour: white. Appearance: crystalline solid.
Between the most significant properties of lithium we find its high specific heat (calorific capacity), the huge temperature interval in the liquid state, high termic conductivity, low viscosity and very low density. Metallic lithium is soluble in short chain aliphatic amines, like etilamine.ike all alkali metals, lithium reacts easily in water and does not occur freely in nature due to its activity, Lithium is a moderately abundant element and its present in The Earthâs crust in 65 ppm (parts per million).
