- 3-78 Nitrous oxide, N20, laughing gas, is a colorless, nontoxic, tasteless, and odorless gas. It is used as an inhalation anesthetic in dental and other surgeries. Because nitrous oxide is soluble in vegetable oils (fats), it is used commercially as a propellant in whipped toppings Nitrous oxide dissolves in fats. The gas is added under pressure to cans of whipped topping. When the valve is opened, the gas expands, thus expanding (whipping) the topping and forcing it out of the can. (a) How many valence electrons are present in a molecule of N20? (b) Write two equivalent contributing structures for this molecule. The connectivity in nitrous oxide is NNO. (c) Explain why the following is not an acceptable contributing structure:arrow_forwardAnswer true or false. (a) The name of a binary ionic compound consists of the name of the positive ion followed by the name of the negative ion. (b) In naming binary ionic compounds, it is necessary to state the number of each ion present in the compound. (c) The formula of aluminum oxide is Al2 O3 . (d) Both copper(II) oxide and cupric oxide are acceptable names for CuO. (e) The systematic name for Fe2 O3 is iron(II) oxide. (f) The systematic name for FeCO3 is iron carbonate. (g) The systematic name for NaH2PO4 is sodium di- hydrogen phosphate. (h) The systematic name for K2HPO4 is dipotassium hydrogen phosphate. (i) The systematic name for Na2O is sodium oxide. (j) The systematic name for PCl3 is potassium chloride. (k) The formula of ammonium carbonate is NH4CO3. 39. (a) A covalent bond is formed between two atoms whose difference in electronegativity is less than 1.9. (b) If the difference in electronegativity between two atoms is zero (they have identical electronegativ- ities),…arrow_forwardPredict whether the following compounds are ionic or molecular:(a) KI, the compound used as a source of iodine in table salt(b) H2O2, the bleach and disinfectant hydrogen peroxide(c) CHCl3, the anesthetic chloroform(d) Li2CO3, a source of lithium in antidepressantsarrow_forward

- - Classify each compound as ionic or molecular. If it is ionic, determine whether the metal forms only one type of ion or more than one type of ion. (a) CoCl2 (b) CF4 (c) BaSO4 (d) NOarrow_forwardBefore the use of systematic names, many compounds had common names. Give the systematic name for each of the following: (a) Blue vitriol, CuSO4*5H2O (b) Slaked lime, Ca(OH)2 (c) Oil of vitriol, H2SO4 (d) Washing soda, Na2CO3 (e) Muriatic acid, HCl (f) Epsom salt, MgSO4*7H2O (g) Chalk, CaCO3 (h) Dry ice, CO2 (i) Baking soda, NaHCO3 (j) Lye, NaOHarrow_forwardIllustrated are four ions — A, B, X, and Y— showing their relative ionic radii. The ions shown in red carry positive charges: a 2+ charge for A and a 1+ charge for B. Ions shown in blue carry negative charges: a 1- charge for X and a 2- charge for Y. (a) Which combinations of these ions produce ionic compounds where there is a 1:1 ratio of cations and anions?(b) Among the combinations in part (a), which leads to the ionic compound having the largest lattice energy? Why?arrow_forward
- Many chemical names are similar at first glance. Give the formulas of the species in each set: (a) Ammonium ion and ammonia (b) Magnesium sulfide, magnesium sulfite, and magnesium sulfate (c) Hydrochloric acid, chloric acid, and chlorous acid (d) Cuprous bromide and cupric bromidearrow_forwardEach of the following compounds contains a metal that can exhibit more than one ionic charge. Name these compounds:(a) Cr2O3(b) FeCl2(c) CrO3(d) TiCl4(e) CoO(f) MoS2arrow_forwardAnswer true or false. (a) For Group 1A and Group 2A elements, the name of the ion each form is simply the name of the element followed by the word ion; for example, Mg21 is named magnesium ion. (b) H2 is named hydride ion. (c) The nucleus of H1 consists of one proton and one neutron. (d) Many transition and inner transition elements form more than one positively charged ion. (e) In naming metal cations with two different charges, the suffix -ous refers to the ion with a charge of 11 and -ic refers to the ion with a charge of 12. (f) Fe31 may be named either iron (III) ion or ferric ion. (g) The anion derived from a bromine atom is named bromine ion. (h) The anion derived from an oxygen atom is named oxide ion. (i) HCO3 2 is named hydrogen carbonate ion. (j) The prefix bi- in the name “bicarbonate” ion indicates that this ion has a charge of 22. (k) The hydrogen phosphate ion has a charge of 11, and the dihydrogen phosphate ion has a charge of 12. (l) The phosphate ion is PO3 42. (m)…arrow_forward
