This polarity makes water molecules attracted to each other. The oxygen-hydrogen bond in the alcohol molecule is also polar. But, the carbon hydrogen bonds in the rest of the alcohol molecule are nonpolar. In these bonds, the electrons are shared more or less evenly.

Answer:

Both polar covalent bonds inside each water molecule and hydrogen bonds inside each water molecule are liable for attraction between water molecules.

Explanation:

Water is a polar protic molecule.
Due to large difference in electronegativity between oxygen and hydrogen atom, two O-H bonds in water molecule are polar.
Due to the presence of polar covalent bonds in water molecule, water molecules attract each other through oppositely polarized ends.
In water molecules, H atom is attached with highly electronegative oxygen atom. Hence hydrogen bonding interaction arises between water molecules.
So, both option (A) and (B) are correct

A solid precipitate is formed from the reaction of lead nitrate and sodium chromate.

LUCKY_DIMON [66]

Lead chromate is a precipitate that is formed on the reaction of lead nitrate with sodium chromate. The best method to separate this precipitate from the solution is filtration.

A precipitate can be defined as an insoluble solid formed in a chemical reaction. It appears as a cloudy and resulted after a reaction.
The lead chromate is yellow colored precipitate that forms after the reaction of lead nitrate with sodium chromate.
The process of separation of insoluble solids from the liquids by the use of filters is known as filtration. Insoluble solids are also called as precipitates these precipitates are formed in a chemical reaction.
Filtration will help in separation of insoluble solid yellow colored lead chromate precipitate from the solution using a porous material or filter that selectively inhibits the passage of solid precipitate material and allows the solution to pass through it.
