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.

The binding agent for all tempera paints is egg.
<h3>What is a binder?</h3>
A binder can be defined as a substance that causes pigment particles to adhere (stick) to one another and remain attached to the surface of a painting.
In painting, eggs are generally used as the binding agent for all tempera paints.

Answer: 42.5 hours
Explanation:
Let the number of hours that the employee work be represented by x.
Since the employee spent 1.7 hours making work calls one week, which was 4% of the employee's total work hours for the week, this can be represented in an equation as:
4% × x = 1.7
4/100 × x = 1.7
0.04 × x = 1.7
0.04x = 1.7
x = 1.7 / 0.04
x = 42.5 hours
The employee worked for 42.5 hours
