\nA chemical change results in the formation of new substances with different chemical properties. Mixing sodium hydroxide (NaOH, a strong base) and hydrochloric acid (HCl, a strong acid) causes a neutralization reaction: NaOH(aq) + HCl(aq) \u2192 NaCl(aq) + H\u2082O(l). Sodium chloride (NaCl) and water (H\u2082O) are produced, which have entirely different chemical properties compared to the reactants. Sublimation, melting, and simple heating of a solid are physical changes, altering the state or temperature but not the chemical identity of the substance.
\n<\/section>\n
\nChemical changes involve the breaking and forming of chemical bonds, resulting in new substances. Physical changes involve alterations in form, state, or appearance without changing chemical composition.
\n<\/section>\n
\nNeutralization reactions are a common type of chemical change where an acid and a base react to form a salt and water. These reactions are often exothermic, releasing heat.
