please upload the correct answer, don't make an error, so I can see all the answers 1. Answer questions about solvents below !a) Why are nonaqueous solvents like ammonia, sulphur dioxide, hydrogensulphide more suitable for polar or polarizable compounds than for the ioniccompounds ?b) Why is sulphuric acid not a good solvents for ionic compounds despite havinga higher dielectric constant and boiling point than water ?c) Strong acids like HCIO4 , HCI, HNO3 and H2SO4 are poor conductors ofelectricity in HCN, KCI, KBr and KCI conduct electricity underequivalentconditions. Will acetic acid conduct electricity or not ?

Why do nonmetals oxides tend to form acids and metal oxides tend to form bases? Metal oxides tend to form bases because the metal does not pull electron density towards itself, and this makes the oxygen electron rich, and the oxygen can then more readily bind a hydrogen atom. Metal oxides tend to form bases because the metal pulls electron density towards itself, and this makes the oxygen electron rich, and the oxygen can then more readily bind a hydrogen atom. Nonmetal oxides tend to form acids because the central atom is electronegative and pull electron density towards itself. Thus, the bond between the oxygen and the hydrogen becomes stronger, and the hydrogen can be released. Nonmetal oxides tend to form acids because the central atom is electronegative and pull electron density towards itself. Thus, the bond between the oxygen and the hydrogen weakens, and the hydrogen can be released.
Describe how you could separate and purify compound A from a mixture of two neutral compounds (A and B) when A comprises 95% of the total and B the other 5% of the total. Assume that A and B have similar polarities.
1. Which statement regarding sulphuric acid is incorrect? a. Concentrated sulfuric acid is about 78% H2SO4 by mass and 10 molar b. It is a strong acid with respect to its first step ionisation c. Its second step ionization is not complete in concentrated solutions d. It is often used as a dehydrating agent because of its strong affinity for H2O 2. Which of the following statements concerning silicon and its bonding is false? a. Silicon dioxide consists of linear molecules b. Silicon has vacant 3d orbitals in its valence shell that can accept electrons from donor atoms c. Silicon does not form very stable Si–Si bonds unless the silicon atoms are bonded to very electronegative elements d. Silicon forms its strongest single bond with oxygen
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)
Write the balanced equation for the neutralization reaction between H3PO4 and NaOH in an aqueous solution. Phases are optional.
