The line segment is describe as a line which joints two points. The word segment is denotes the end points of the line. The symbol of the line segment is AB. This symbol is indicating a line from the point A to the point B.
- Generally, the line segment has two endpoints. The meeting point of two line segments is called as the vertex and also it is considered as a common endpoint on the other hand line is a straight path of points that goes on and on in two directions
- Vertex is a point where two rays meet OR where the sides of a polygon meet OR the point where three or more edges of a solid figure meet and the angle is Formed by two rays that have the same endpoint

Answer:
See explanation
Explanation:
Extraction has to do with the separation of the components of a mixture by dissolving the mixture in a set up involving two phases. One phase is the aqueous phase (beneath) while the other is the organic phase (on top). The solvents used for the two phases must not be miscible. Water commonly is used for the aqueous phase.
Ethanol is an important solvent in chemistry but the solvent is miscible with water in all proportions. As a result of this, ethanol is a poor solvent for carrying out extraction.
Answer:
Choice A: approximately .
Explanation:
Note that the unit of concentration, , typically refers to moles per liter (that is: .)
On the other hand, the volume of the two solutions in this question are apparently given in , which is the same as (that is: .) Convert the unit of volume to liters:
- .
- .
Calculate the number of moles of formula units in that of the solution:
.
Note that (sulfuric acid) is a diprotic acid. When one mole of completely dissolves in water, two moles of ions will be released.
On the other hand, (sodium hydroxide) is a monoprotic base. When one mole of formula units completely dissolve in water, only one mole of ions will be released.
ions and ions neutralize each other at a one-to-one ratio. Therefore, when one mole of the diprotic acid dissolves in water completely, it will take two moles of to neutralize that two moles of produced. On the other hand, two moles formula units of the monoprotic base will be required to produce that two moles of . Therefore, and formula units would neutralize each other at a two-to-one ratio.

.
Previous calculations show that of was produced. Calculate the number of moles of formula units required to neutralize that
.
Calculate the concentration of a solution that contains exactly of formula units:
