Aflask contains 1/3 mole of h2 and 2/3 mol of he. compare the force on the wall per impact of h2 relative to that for he.

1/2

Explanation:

By Raoult's Law, the pressure of a gas in a gas mixture, is its mole fraction multiplied by the total pressure of the gas mixture. Thus, calling Pt as the total pressure:

The pressure is the force divided by the area, thus:

Because the area is the same:

electron microscopy and scanning tunneling microscopes gives us a greater understanding of atoms by being able to see the atom itself, and lets us see some atomic reactions.

explanation:

why is arctic sea ice important? arctic sea ice keeps the polar regions cool and moderate global climate. sea ice has a bright surface; 80 percent of the sunlight that strikes it is reflected back into space. as sea ice melts in the summer, it exposes the dark ocean surface.
