Water molecules are polar (positive charge zones and negative charge zones) this makes the attraction of a na+ ion or a cl- ion to occur.

<h3>How are the water molecules composed?</h3>

This class of molecules that have a distribution of charges are called polar and, consequently, form bonds called hydrogen bonds with other molecules.

These molecules have a permanent dipole moment, that is, they have a structure called dipolar (two poles), this arrangement gives water great power to dissolve substances within it.

Therefore, we can conclude that water molecules are polar (positive charge zones and negative charge zones) this makes the attraction of a na+ ion or a cl- ion to occur.

Find AUB and ANB for the set A and B<br> A [4,2,9], B [7,5,1

Gnesinka [82]

Answer:

AUB={1,2,4,5,7,9}

ANB={ }

Explanation:

AUB means that you have to combine all the element in each set whereas ANB is the set of similar elements in set A and set B. As there is no same elements in set A and set B therefore ANB will be called as null set.

What relationship exists between a homogeneous mixture and the number of phases in the mixture

Gwar [14]

The relationship that exists between a homogeneous mixture and the number of phases in the mixture is one phase.

Given that there is a relationship exists between a homogeneous mixture and the number of phases in the mixture.

We are required to tell the name of the relationship that exists between a homogenous mixture and the number of phases in the mixture.

A homogeneous mixture is basically a gaseous, liquid or solid mixture that has the same proportions of its components throughout a given sample.

The name of the relationship is one phase.

A phase is basically a relationship between the cycles of different periodic waves.

Hence the relationship that exists between a homogeneous mixture and the number of phases in the mixture is one phase.
