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.For purposes of computing a formula mass, it is helpful to rewrite the formula in the simpler format, Al 2 S 3 O 12. Following the approach outlined above, the formula mass for this compound is calculated as follows: 2 Al mass = 2 x 26.9815 amu. = 53.9630 amu. 3 S masses = 3 x 32.066 amu. = 96.198 amu.For example, the ionic compound sodium oxalate is comprised of Na + and \(\ce{C2O4^2-}\) ions combined in a 2:1 ratio, and its formula is written as Na 2 C 2 O 4. The subscripts in this formula are not the smallest-possible whole numbers, as each can be divided by 2 to yield the empirical formula, NaCO 2 .Polyatomic ions. In this article, we will discuss polyatomic ions. The prefix poly- means many, so a polyatomic ion is an ion that contains more than one atom. This differentiates polyatomic ions from monatomic ions, which contain only one atom. Examples of monatomic ions include \text {Na}^+ Na+, \text {Fe}^ {3+} Fe3+, \text {Cl}^- Cl−, and ...Solution. Because the ionic compound must be electrically neutral, it must have the same number of positive and negative charges. Two aluminum ions, each with a charge of 3+, would give us six positive charges, and three oxide ions, each with a charge of 2−, would give us six negative charges. The formula would be Al 2 O 3.

Sep 19, 2022 · 3. Table 3.5. 3: Names of Some Transition Metal Ionic Compounds. Out-of-date nomenclature used the suffixes – ic and – ous to designate metals with higher and lower charges, respectively: Iron (III) chloride, FeCl 3, was previously called ferric chloride, and iron (II) chloride, FeCl 2, was known as ferrous chloride. Chemistry library > Atoms, compounds, and ions > Ions and compounds © 2023 Khan Academy Terms of use Privacy Policy Cookie Notice Molecules and compounds Google Classroom Compounds can be classified as ionic or covalent. Molecules are the simplest unit of a covalent compound, and molecules can be represented in many different ways.Ionic compounds are composed of positive and negative ions held together by ionic bonds. An Ionic bond is a type of bond that forms between a metal and a non-metal. Molecular compounds are compounds made up of nonmetals. A covalent bond is a type of bond that occurs between two nonmetals.

Recall that a molecular formula shows the number of atoms of each element that a molecule contains. A molecule of water contains two hydrogen atoms and one oxygen atom, so its formula is \(\ce{H_2O}\). A molecule of octane, which is a component of gasoline, contains 8 atoms of carbon and 18 atoms of hydrogen.

Avogadro’s number (NA): experimentally determined value of the number of entities comprising 1 mole of substance, equal to 6.022×1023mol−1 6.022 × 10 23 mol − 1. formula mass: sum of the average masses for all atoms represented in a chemical formula; for covalent compounds, this is also the molecular mass.The transfer and sharing of electrons among atoms govern the chemistry of the elements. During the formation of some compounds, atoms gain or lose electrons, and form electrically charged particles called ions (Figure 3.6.1 ). Table 3.6.1: (a) A sodium atom (Na) has equal numbers of protons and electrons (11) and is uncharged.Example 1. Write the molecular formula of each compound.

Solution. To calculate the percent composition, the masses of C, H, and O in a known mass of C 9 H 8 O 4 are needed. It is convenient to consider 1 mol of C 9 H 8 O 4 and use its molar mass (180.159 g/mole, determined from the chemical formula) to calculate the percentages of each of its elements: % C = 9 mol C × molar mass C molar mass C 9 H ...One important aspect about ionic compounds that differs from molecular compounds has to do with dissolving in a liquid, such as water. When molecular compounds, such as sugar, dissolve in water, the individual molecules drift apart from each other. When ionic compounds dissolve, the ions physically separate from each other. We can use a ...Because an ionic compound is not made up of single, discrete molecules, it may not be properly symbolized using a molecular formula.
