Yes, that is correct. The bonds that form spontaneously release energy because the molecule formed is more stable (and therefore at a lower energy) than each of the elements separately. The molecule therefore releases energy by forming a bond, so q (or delta H) is negative
yes, I believe so. When bonds break, energy is required to break the bond so it is positive. However, when bonds are formed, energy is released that is why it is negative. So breaking a bond is endothermic while forming a bond is exothermic.
