- Draw the lewis and skeletal structure of (CH3CH2O)2COarrow_forward(a) (i) (ii) (iii) With the aid of a simple schematic, explain what covalent bonding is and how it is formed. What are the differences between a covalent bond and an ionic bond? Which type of bond is found in crystalline silicon? At room temperature do you expect an ionic crystal to be a good electrical conductor or a good electrical insulator? Explain why.arrow_forwardCalculate the mass of acid dissolved in 389 mL of 0.725 M hydrofluoric acid. 5.64 g O 5.77 g 10.3 g 5.93 g O 16.5 g Which of the following is the correct Lewis Structure for the SeBr₂ molecule?

- Draw a Lewis structure for diimide, H-N=N-H, explain how the Lewis structure is drawn. Then, using valence bond theory, describe the bonding in this compound. What orbitals overlap to form the bond between nitrogen atoms in this compound? Explain and elaborate.arrow_forwardDiscuss the nature of the bonding in the nitrate ion (NO5). Draw the possible Lewis resonance diagrams for this ion. Use the VSEPR theory to determine the steric number, the hybridization of the central N atom, and the geometry of the ion. Show how the use of resonance structures can be avoided by introducing a de-localized 7 MO. What bond order is predicted by the MO model for the N-O bonds in the nitrate ion?arrow_forwardGive the hybridization and oxidation state for sulfur in SO2, in SO3, and in H2SO4.arrow_forward
- Draw a Lewis electron-dot diagram for the disilicate ion (Si2O9 ). What changes in this structure would be neces- sary to produce the structure of the pyrophosphate ion (P2O¯) and the pyrosulfate ion (S2O?¯)? What is the analogous compound of chlorine?arrow_forwardAn ionic compound, LiN((CH3)3Si)2 is commercially available and can be synthesised by deprotonation of ((CH3)3Si)2NH with C4H9Li. Draw an orbital diagram and a sketch to show the overlap of orbitals that produce the bonding in ((CH3)3Si)2N− anion and predict whether the Si−N−Si bond angle in the ((CH3)3Si)2N− anion is larger than, equal to or smaller than 109.5. explainarrow_forward[References] Hydrogen cyanide, HCN, is prepared from ammonia, air, and natural gas (CH4) by the following process: 2NH3 (g) + 30, (g) + 2CH, (g) → 2HCN(g) + 6H, 0(g) Hydrogen cyanide is used to prepare sodium cyanide, which is used in part to obtain gold from gold-containing rock. If a reaction vessel contains 6.10 g NH3, 13.0 g 02, and 5.83 g CH4, what is the maximum mass in grams of hydrogen cyanide that could be made, assuming the reaction goes to completion as written?
