Please answer all 4! I need it ASAP

1. CH3COOH(aq) 5. NaHCO3 (aq) 2. HCN(aq) 6. NaOH(aq) 3. H2SO3(aq) 7. Na2O(aq) 4. H3PO4(aq) 8. NH3(aq) Numerical Response 1 Arrange the acidic solutions from strongest to weakest Use the following information to answer the next three questions Citric acid, symbolized H3Ct(aq), is a triprotic acid that fulfils a variety of roles. It is used as a food preservative as well as a flavouring agent for foods, beverages, and confections. It is also used to condition water, remove sulphur dioxide from smelter waste, and polish metals such as stainless steel. In addition, citric acid is a very important vitamin in the human body. Citric acid ionizes through this series of steps: H3Ct(aq)+H2O(I)H3O+(aq)+H2Ct(aq)H2Ct(aq)+H2O(l)H3O+(aq)+HCt2(aq)HCt2(aq)+H2O(I)H3O+(aq)+Ct3(aq) The Ka values for the three steps in the ionization, in random order, are I. 7.0104 II. 6.5106 III. 1.8105 3. The Ka values for H3Ct(aq),H2Ct(aq), and HCt2 (aq), respectively, are numbered A. I, II, III B. I, III, II C. II, I, III D. II, III, I 4. Examples of two conjugate acid-base pairs in the above reactions are A. H3Ct(aq) and H2O(1),H2Ct(aq) and H3O+(aq) B. H2Ct(aq) and H3O+(aq),HCt2 (aq) and H2O(1) C. H3Ct(aq) and HCt2(aq),H3O+(aq) and H2O(1) D. HCt2(aq) and Ct3(aq),H3O+(aq) and H2O(1) 5. The species that is amphiprotic is A. Ct3(aq) B. H3Ct(aq) C. H3O+(aq) D. H2Ct(aq)
