    Why isn't acetic acid a strong electrolyte/acid

    Acetic acid is a weak acid because acetate and a free proton are not as thermodynamically stable as acetic acid. Consider the acid dissociation constant (K_a): an acid with a low K_a, has an equilibrium concentration of the acid that is much greater than the product of the equilibrium...

    Experimenting with Liquid Nitrogen: Who's Right?

    Yes, it is liquid oxygen. If your balloon is clear, then the liquid should appear pale-blue. You should not attempt to burn it.

    Can electroplating Cu on gold improve adhesion?

    I am surprised that you are having an adhesion problem. http://www.springerlink.com/content/q1346p3730605716/" What precursors are you using? What's the pH?

    Why does CO2 keep keep heat within the atmosphere? (on the molecular level)

    Molecules do reflect light. The sky wouldn't be blue if atmospheric molecules weren't around to scatter photons (elastic-Rayleigh scattering). And if molecules didn't inelastically scatter photons, then we couldn't probe their vibrational modes with Raman spectroscopy.

    Graduate What happens when a co2 molecule absorbs an infra red photon?

    Although CO2 doesn't have a permanent dipole moment, the permanent dipole moment of a static molecule tells you nothing about its interaction with an infrared photon. If you want to consider a molecules ability to absorb in the IR, then you need to consider how the dipole moment changes as the...
