This is how it was used ---- If there were no salt added to the ice, it would melt at 32 degrees Fahrenheit and eventually the ice water and mix would come to equilibrium at 32 degrees.

True or False? If false, write the correct term that's in UPPERCASE.

According to present atomic theory, the location of an ELECTRON in an atom is best represented by a probability cloud.

The mass of an ELECTRON is about equal to the mass of a proton.

Two isotopes of carbon are carbon-12 and carbon-14. These isotopes differ from one another by two ELECTRONS.

NONMETALS are poor conductors of heat and electricitiy.

Seven electrons in the outermost energy level is a characteristic of a METAL.

If you were on a plane going down, not taking into account wind and such, lets say you were standing on top of it, and thusly would be falling at the same speed. If you jumped upwards like two feet before it crashed, not taking into account flames and such, would you live? It seems sorta like you could, cause the world is constantly spinning, and it's the same sort of idea--you take ont eh energy and movement of the larger object you're on, but when you jump you seperate yourself from it and would start over--two feet above ground.
Ideas?
