Which formulas represent one ionic compound and one molecular compound
Answers. 1. The symbol for the element oxygen, O, represents both the element and one atom of oxygen. A molecule of oxygen, O 2, contains two oxygen atoms; the subscript 2 in the formula must be used to distinguish the diatomic molecule from two single oxygen atoms. 2.Sodium chloride is an ionic compound composed of sodium cations, Na +, and chloride anions, Cl −, combined in a 1:1 ratio. The formula mass for this compound is computed as 58.44 amu (Figure 3.6.3 ). Figure 3.6.3: Table salt, NaCl, contains an array of sodium and chloride ions combined in a 1:1 ratio. Its formula mass is 58.44 amu.Science Chemistry Chemistry questions and answers QUESTION 4 Which formulas represent one ionic compound and one molecular compound a. Cl2 and H2 b. BaCl2 and N204 c.

Molecular formulas are also used as abbreviations for the names of compounds. The structural formula for a compound gives the same information as its molecular formula (the types and numbers of atoms in the molecule) but also shows how the atoms are connected in the molecule. The structural formula for methane contains symbols for one C atom ...Sodium chloride is an ionic compound composed of sodium cations, Na +, and chloride anions, Cl −, combined in a 1:1 ratio. The formula mass for this compound is computed as 58.44 amu (Figure 3.6.3 ). Figure 3.6.3: Table salt, NaCl, contains an array of sodium and chloride ions combined in a 1:1 ratio. Its formula mass is 58.44 amu.Ionic and molecular compounds are named using somewhat-different methods. Binary ionic compounds typically consist of a metal and a nonmetal. The name of the metal is written first, followed by the name of the nonmetal with its ending changed to – ide. For example, K 2 O is called potassium oxide.Leave out all charges and all subscripts that are 1. AlN AlN. Li2O Li 2 O. An alternative way to writing a correct formula for an ionic compound is to use the crisscross method. In this method, the numerical value of each of the ion charges is crossed over to become the subscript of the other ion.
Ammonia is a compound of nitrogen and hydrogen as shown below: Figure 1.14.1 1.14. 1: The molecular formula for ammonia. NH3.

(1) N 2 and SO 2 (3) BaCl ...Sodium chloride is an ionic compound composed of sodium cations, Na +, and chloride anions, Cl −, combined in a 1:1 ratio. The formula mass for this compound is computed as 58.44 amu (see Figure 3.4 ). Figure 3.4 Table salt, NaCl, contains an array of sodium and chloride ions combined in a 1:1 ratio. Its formula mass is 58.44 amu.
The charge of the metal ion is determined from the formula of the compound and the charge of the anion. For example, consider binary ionic compounds of iron and chlorine. Iron typically exhibits a charge of either 2+ or 3+ (see ), and the two corresponding compound formulas are FeCl 2 and FeCl 3. The simplest name, “iron chloride,” will, in ...Hydrogen and chlorine combine by sharing one electron to make the compound HCl. Similarly, oxygen, nitrogen, and carbon make 2, 3, and 4 covalent bonds with hydrogen to complete their octet and make compounds H 2 O, NH 3, and CH 4, respectively, as illustrated in Fig. 3.1.1. Figure 3.1.1 3.1. 1: Examples of covalent bonds where Cl, O, N, …Figure 4.7. 4. (A) Distilled water does not conduct electricity. (B) A solid ionic compound also does not conduct. (C) A water solution of an ionic compound conducts electricity well. In the first beaker, distilled water does not conduct a current because water is a molecular compound. ….
