Answer/ explanation :

In CO2 molecule, the angle between O-C-O is 180, therefore, when the oxygen atom attracts the electron pair towards itself, then it becomes partially negative and the carbon atom becomes partially positive. The bonds in O=C=O are pointing opposite each other and the bond dipoles cancels each other thereby making it zero.

The dipole in O-H bonds cannot cancel out and that is why water has an overall molecular dipole of 1.85D.

CO2 is a linear molecule, so the dipoles are symmetrical. The dipoles are equal in both magnitude but are differ in point facing opposite directions.

Write the neutralization reaction that occurs between h2se and lioh.

Pie

Answer: -

H₂Se + 2 LiOH → Li₂Se + 2 H₂O

Explanation: -

Acid given = H₂Se

Base given = LiOH

We know that in a neutralization reaction,

Acid + base = salt + water

Formula of water = H₂O

Formula of salt = Li₂Se

Thus the balanced chemical equation for the neutralization reaction is

H₂Se + 2 LiOH → Li₂Se + 2 H₂O

To separate a mixture of benzoic acid and fluorene, we are going to use an acid-base extraction technique. Most carboxylic acids

pentagon [3]

Answer: please find attached to see the structure.

1. THE STRUCTURE OF BENZOIC ACID AND FLUORENE, soluble in ether and insoluble in water.

2. THE STRUCTURE OF CARBOXYLIC ACID BEEN EXTRACTED.

Explanation: the mixture of benzoic acid and fluorene are the first diagrams which shows the carboxylic acid attached to the benzene ring, which are soluble in ether and insoluble in water. When dissolved in NaOH(aq) is the carboxy ion becomes soluble in water but insoluble in ether, this is seen in the second diagram.

The third diagram shows the carboxylic acid been precipitated and soluble in ether but insoluble in water.

NOTE THE TWO MAIN DIAGRAM IS THE FIRST AND THE LAST DIAGRAM, WHERE CARBOXYLIC ACID DISSOLVES IN AQUEOUS SODIUM HYDROXIDE, AND WHEN THE ACID IS BEEN PRECIPITATED IN AQUEOUS HCl.

ALSO NOTE THE CHANGE IN BENZOIC RING MIXED WITH FLUORENE TO THAT OF THE ACID BEEN EXTRACTED.

Hope together with the picture, this has helped you.
