Answer:
A) It must be negative
Explanation:
A spontaneous reaction in Chemistry is that which is proceeding in a particular direction without the intervention of any external effect. As a spontaneous reaction proceeds (which can be relatively slow), free energy ΔG, which is the available energy for work, is released.
Gibbs free energy, ΔG, is released during a spontaneous process and hence the ΔG is negative because the reactants have more free energy than the products, hence, no energy input is needed for the reaction to proceed forward but rather an energy output. This is what makes a negative ΔG depict a spontaneous reaction.
Potential energy
Reason why: because the quarterbacks arm has the potential to throw a ball but since it is not throwing the ball, the energy is being held... this holding of energy is called potential energy
Ability to move up through thin tunes because a physical property is something you can observe about the matter. Out of all of them this one does not fit.
Answer:
give us something else to work with or this is just the best guess
