- Follow the directions of Question 1 for (a) IO2- (b) SiF4 (c) BrI3 (d) CN-arrow_forwardDescribe the molecular structure around the indicated atom or atoms: (a) the sulfur atom in sulfuric acid, H2SO4[(HO)2SO2] (b) the chlorine atom in chloric acid, HClO3[HOClO2] (c) the oxygen atom in hydrogen peroxide, HNO3[HONO2] (d) the nitrogen atom in nitric acid, HNO3[HONO2] (e) the oxygen atom in the OH group in nitric acid, HNO3[HONO2] (f) the central oxygen atom in the ozone molecule, O3 (g) each of the carbon atoms in propyne, CH3CCH (h) the carbon atom in Freon, CCl2F2 (i) each of the carbon atoms in aliene, H2CCH2arrow_forwardDetermine if the following expressions are true or false: True or false 1. Be is the only element of Group 2A that forms covalent compounds. 2. Al forms only tetrahedral compounds. 3. B is metalloid and semiconductor. 4. The SiO44‒ ion is tetrahedral. 5. In compound N2O5, nitrogen has an oxidation number of +5. 6. P forms only covalent compounds. 7. H3PO3 is triprotic acid. 8. HClO4 is explosive. 9. Br2 (l) oxidizes I2 (s). 10. The XeF4 molecule is tetrahedral.arrow_forward
- Using Lewis symbols and Lewis structures, diagram the formation of SiCl4 from Si and Cl atoms.arrow_forwardDraw all of the Lewis structures of O22- which obey the octet rule and use this Lewis structure or these resonance structures to predict how many covalent bonds connect each oxygen atom in the real structure to the central O atom. Assume that the octet rule is followed for the O atom when you draw your structure(s). Pick the correct statement from the choices below. a) Each oxygen atom is connected to the central O atom with 1 covalent bonds. b) Each oxygen atom is connected to the central O atom with 1.33 covalent bonds. c) Each oxygen atom is connected to the central O atom with 2 covalent bonds. d) Each oxygen atom is connected to the central O atom with 1.67 covalent bonds. e) Each oxygen atom is connected to the central O atom with 1.25 covalent bonds.arrow_forwardUse Intermolecular Forces to explain why CF4 is a gas at room temperature but CCl 4 is a liquid.arrow_forward
- CH,OH The name carbohydrate comes from the fact that many simple sugars have chemical formulae that look like water has simply been added to carbon. (The suffix hydrate from the Greek word hydor ("water") means "compound formed by the addition of water.") OH The actual chemical structure of carbohydrates doesn't look anything like water molecules bonded to carbon atoms (see sketch at right). But it is nevertheless possible to chemically extract all the hydrogen and oxygen from many simple carbohydrates as water, leaving only carbon behind. If you search the Internet for "reaction of sulfuric acid and sugar" you will find some impressive videos of this. НО OH ОН The actual chemical Suppose you had (200. g) of ordinary table sugar, which chemists call sucrose, and which has the chemical formula C,,H,,0,. 22 structure of glucose. 12 Calculate the maximum mass of water you could theoretically extract. Be sure your answer has a unit symbol, and round it to 3 significant digits. x10 ?arrow_forwardA nonmetal like oxygen forms both ionic and covalent bonds, depending on the identity of the element to which it bonds. What type of bonding is observed in CaO and CO 2? Explain why two different types of bonding are observed.arrow_forwardWhat possible error(s) exist in the Lewis structure (assume we are trying to represent the best possible Lewis structure for the NO₂S ion knowing N is the central atom in this polyatomic ion)? [:ö==S: N= CO :O: The best structure would have double bond and two lone pairs on each oxygen atom and a single bond with three lone pairs on the sulfur. There are no errors. This is the best possible structure. The Lewis structure above does not minimize formal charges, thus is the not the best possible structure. The nitrogen atom has an expanded octet, and this structure is impossible. The Lewis structure contains the wrong number of electrons, thus this structure is impossible.arrow_forward
- The attractive force between a pair of Sr2+ and O2- ions is 1.52 x 108 N and the ionic radius of O2- ions is 0.134 nm. Calculate the ionic radius of the Sr2+ ion. (Given: Electron charge, e = 1.6 x 101ºC, the permittivity of free space, Eo = 8.85 x 101ºC²N'm²)arrow_forwardAn elemental analysis of a hydrocarbon, which contains only carbon and hydrogen, shows the mass%: element mass% carbon 92.26 hydrogen 7.743 (A) * Determine the empirical formula of the hydrocarbon. (B) The compound has a molar mass of 26.04 g/mol. Determine its molecular formula. (C, Draw the Lewis structure of the molecular compound. Count the total number of sigma bonds and pi bonds each, present in the molecule. (D, What is the hybridization of carbon in the molecule? Explain.arrow_forwardwhy CO2 are nonpolar and SO2 are polar in structure although they are both having 2 Oxygen?arrow_forward
