Web(b) Acid-Base reaction: There is no change in oxidation number for any of the elements in this reaction—hence it is NOT an oxidation- reduction reaction. H2SO4 is an acid, and Zn(OH)2 acts as a base. (c) Oxidation-Reduction: Ca(s) has an oxidation number of 0, while Ca2+(aq) has an oxidation number of +2—hence Ca is being oxidized. Web10. What will happen if the following acids; HCL, H2SO4, H3PO4 and H2SO4 is mixed with zinc. Answer: I think . Explanation: The metal zinc readily reacts with hydrochloric acid to produce hydrogen gas (H2) and zinc chloride (ZnCl2). ... The zinc reaction produces the heat and hence has the negative enthalpy. 11.
