When a stable diatomic molecule spontaneously forms from its atoms, what are the signs of delta h, delta s, and delta g? a. + + + b. + - - c. - - + d. - - -

H will definitely be positive because a bond is always more stable than no bond surely if it is a sigma bond.
For G you can't really know because you don't know how much energy is provided by the bond and if it outways the loss in disorder.

The reaction will become more spontaneous with a lower temperature because H tells you the reaction is exotherm

They are like other investigations? say there was a murder u have to do blood test and finger prints which run through a lab.
