Which is a unique feature of jupiter?

a.
the least dense planet in the solar system

b.
the largest, most massive planet

c.
rotates on an axis tilted entirely sideways

d.
the most distant planet from the sun

I would say the answer is A, because Jupiter is the least dense planet in the solar system. It is the largest planet in our solar system, but that is not what answer choice says. Jupiter does not rotate on an axis completely sideways, that is Uranus, and is not the most distant planet from the sun.

Spontaneity tell us the direction of the reaction, but not how fast it goes. gibbs free energy brings together enthalpy, entropy and temperature in one easy formula. g = h - ts. and, finally the sign of delta g is always negative for a spontaneous reaction.
