Which of the following is an example of a MOLECULE? *
2 points
H20
NaF
Mg3N2
All of the above are molecules

Other familiar molecules include water,consisting of two hydrogen atom and one oxygen atom(H2O),Carbon dioxide,consisting of one carbon atom bonded to two oxygen atom(CO2).

Explanation:

And sulfuric,Consisting two hydrogen atom,one sulfur atom,and four oxygen atom(H2SO4).

the molecules move in straight line until they collide with each other or with the walls of the container. collisions are perfectly elastic; when two molecules collide, they change their directions and kinetic energies, but the total kinetic energy is conserved.

explanation:

the electrical  conductivity  of asolution  of an electrolyte is measured by determining the resistance of thesolution  between two flat or cylindrical electrodes separated by a fixed distance.
