- What is reducing agent in organic chemistry? give some examples with explanation? what functional groups are reduced by NaBH4Place the following acids in order of increasing strength: -H3PO4, H3PO2 and H3PO3. Explain your reasoning based on molecular structure.(Thanks for the help if you can break down the steps and provide drawings(needed) during the answer since i am trying to see if i have solved this in the right way not copy :)) Draw the heme environment in oxymyoglobin and explain how the geometric data for the attached oxygen molecule may be understood. Fe O (bond length) = 1.809 Å; O-O (bond length ) = 1.246 Å; Fe - O - O (bond angle) = 123 \deg

- True or false. The molar mass of a nonpolar molecule is mainly used when evaluating the strength of its IMFA against other non-polar molecules.a) Compare between equivalence point and endpoint. Distinguish which point comes first. b) Sulfanilamide, C6H4N2O2S is a sulfonamide antibacterial drug. The purity of sulfanilamide (168.18 g/mol) can be determined by the following steps. First, oxidize sulfur to SO₂ gas. Next, allow SO₂ gas generated to pass through H₂O₂ to produce H₂SO4. The acid is then titrated with NaOH standard solution. Given a 0.5136 g of sulfanilamide sample required an average titre volume of 48.13 mL 0.1251 M NaOH. Suggest a suitable indicator to be used in this titration and predict the purity of sulfanilamide being analysed. (Note: 1 mol sulfanilamide = 1 mol H₂SO4)PAP Chemistry-2903012-42100P-1/ Le Chatelier's Principle/ Lesson 128 2. Zinc (Zn) granules react slowly with dilute hydrochloric acid (HCI), but much faster if the acid is concentrated. Zn(s) 2HCI(aq)ZnCl2(aq) + H2(g) Zinc + Hydrochloric Acid Zinc Chloride + Hydrogen What causes the reaction to proceed faster with concentrated acid? The concentrated hydrochloric acid causes more hydrogen gas to be produced. The pressure of hydrogen gas molecules increases as concentration increases. The concentrated hydrochloric acid molecules move faster than in dilute acid. There are more collisions between the zinc and concentrated hydrochloric acid. PREVIOU
