This is because it has a full outer valence shell! so there are 8 electrons and that means it doesn't have the urge the gain anymore
Answer:
The correct answer is: 1.316 . 10⁻³ m³/kg.
Explanation:
The density (ρ) of a substance is the ratio of its <em>mass (m)</em> to its <em>volume (V)</em>. At constant temperature and pressure, its value is constant and it is an intrinsic property of materials. The units of density are kg/m³.
The specific volume (ν) of a substance is the ratio of its <em>mass</em> to its <em>volume</em>. We can see that it is the reciprocal of density and an intrinsic property of matter as well. Therefore, the units of specific volume are m³/kg.
Given we know the density of the liquid, we can use this relationship to find out its specific volume:
A Bunsen valve is a simple device that
Select one:
a. Allow gas flow in only one direction
b. Does all of these
c. Keeps a flask sealed
d. Keeps the salts from plugging the tube
Answer:
a. Allows gas flow in one direction
Explanation:
A Bunsen valve is a simple device that should not be confused with Bunsen burner.
It is fitted with glass tubes and a thin opening is made using scalpel. When the pressure becomes excessive it opens and vents out the excess gas hence maintaining unidirectional flows of the gas.
