Salts, such as sodium chloride (NaCl), have atoms bound together through ionic bonds. Ionic bonds are formed due to the difference in charge between two atoms (i.e. sodium is a positively charged cation, whereas chloride is a negatively charged anion). Since ...
When a substance freezes, is energy being added or removed?Phase Change:Phase change occurs when the matter changes from one state to another state. The phase change either absorbs the energy or releases the energy depending on the phase change....
