WebThe chemical equation is: Zn + H 2 SO 4 → ZnSO 4 + H 2. Thus, the reactions between metals and some acids can be predicted with the help of the reactivity series. Single Displacement Reactions Between Metals. … WebTherefore materials with high chemical resistance are less likely to corrode. Highly chemical resistant materials such as acrylic resins are also regarded as functionalize for corrosion-resistant materials because of their resistance to chemical activity. Chemical resistance also can affect the physicochemical properties.
