True.
This is a combination of an anion and a cation to form a neutral compound.
Explanation:
It is also important to note that potential energy can be positive, zero or negative. ... Now that the kinetic energy and potential energy have been defined, we can now apply the Law of Conservation of Energy. In other words, the kinetic energy plus the potential energy equals a constant (KE+PE=Constant).
Resonance or mesomerism is applicable to structures that cannot be formed with a single bond alone. Thus, for the structure of HCO2, there can be 2 resonance structures. In each structure, the formal charges are
C=0;
C=0
Oxygen=0
C-O=-1
H=0
HCO2-'s structure is a mixture of the two resonance structures. Hope this helps.
