WebHydrofluoric acid is manufactured by the reaction of acid-grade fluorspar (CaF2) with sulfuric acid (H2SO4) as shown below: CaF2 H2SO4 → CaSO4 2HF A typical HF plant is … 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.

WebJan 8, 2024 · ΔHºf H 2 O = -241.8 kJ/mole 3: Multiply These Values by the Stoichiometric Coefficient In this case, the value is four for carbon dioxide and two for water, based on the numbers of moles in the balanced equation : vpΔHºf CO 2 = 4 mol (-393.5 kJ/mole) = -1574 kJ vpΔHºf H 2 O = 2 mol ( -241.8 kJ/mole) = -483.6 kJ WebAnswer (1 of 2): B2O3 is an oxide of Boron. I assume reaction would occur in aqueous medium! So, B2O3 would be converted to boric acid in aqueous medium. Boric acid when treated with NaOH produces Sodium MetaBorate, NaBO2. NaBO2 is easily hydrolysed back to Boric acid, H3BO3. So end point is no... quidway netengine 08e
