B. Hydrogen is the answer
There would be 79 electrons present in each atom of gold. I hope this helps :)
Pressure =vapor pressure of 2 methlypentane at 150F. If you
The answer is weak intermolecular attractions volume and shape of container. The molecules of gases have high kinetic energy compared to those of liquids and solids hence they are farther apart from one another. This results to weak intermolecular forces. Gases also expand to fit the container hence have no definite shape or volume.
