1. Hii I am in desperate need in help with springs. If you know Hooke's law you most likely know of the experiment i am talking about, so i am wondering if a force is acting upon a metal spring, and it doesn't have an extension does this mean that both force, the force of the spring and the force of gravity acting upon the mass are in equilibrium?

and also just wondering if this is true does it mean that the spring has force which holds it there or energy?

2. for every force there is an equal and opposite reaction force.

not quite could you describe what happens in the experiment?

Not entirely sure which experiment you mean, but if you add a mass to it and the spring doesn't extend, then I believe the tension is equal to the weight. For equilibrium there must be no resultant force so if it it doesnt move I'm guessing its in equilibrium.
