Review of Selected Concepts Related to Nomenclature
Write the chemical formula of each of the following. The blue spheres represent nitrogen atoms and the red spheres oxygen atoms. Oxygen is written last in the formulas that include oxygen.
(a)
Interpretation:
The chemical formula of each of the following is to be written. The blue spheres represent nitrogen atoms and the red spheres oxygen atoms. Oxygen is written last in the formulas that include oxygen.
Concept introduction:
The particle of an element or compound in the written format is denoted by the chemical formulas. The symbols of elements in a particular substance covers the formula of the required substance.
Answer to Problem 1E
The chemical formula of (a) is written as N2
Explanation of Solution
Generally, in a formula, the total number of atoms of the element under study is shown by a subscript number immediately following the symbol. Notably, the subscript does not have the number when only one atom of an element present in the formula. The number of each kind of atom which makes up the particle generally called as the composition, is denoted by the chemical formula. Commonly, elements can be madeup of molecules having single atom, two atoms or complex multi-atoms. Coversely, when the substance itself is an element it should have all atoms of the same element. In the above example (a), the two lobes are having the same blue color which is for the element nitrogen.
Total number of lobes of nitrogen (N) = 2
Chemical formula = N2
Thus, the chemical formula of the colored lobes (a) is written.
(b)
Interpretation:
The chemical formula of each of the following is to be written. The blue spheres represent nitrogen atoms and the red spheres oxygen atoms. Oxygen is written last in the formulas that include oxygen.
Concept introduction:
The particle of an element or compound in the written format is denoted by the chemical formulas. The symbols of elements in a particular substance covers the formula of the required substance.
Answer to Problem 1E
The chemical formula of (b) is written as NO2
Explanation of Solution
Generally, in a formula, the total number of atoms of the element under study is shown by a subscript number immediately following the symbol. Notably, the subscript does not have the number when only one atom of an element present in the formula. In the above example (b), the two lobes are having the same color which is for the element oxygen and one lobe is having the color for nitrogen.
Total number of lobes of nitrogen (N) = 1
Total number of lobes of oxygen (O) = 2
Chemical formula = NO2
Thus, the chemical formula of the colored lobes (b) is written.
(c)
Interpretation:
The chemical formula of each of the following is to be written. The blue spheres represent nitrogen atoms and the red spheres oxygen atoms. Oxygen is written last in the formulas that include oxygen.
Concept introduction:
The particle of an element or compound in the written format is denoted by the chemical formulas. The symbols of elements in a particular substance covers the formula of the required substance.
Answer to Problem 1E
The chemical formula of (c) is written as N2O
Explanation of Solution
Generally, in a formula, the total number of atoms of the element under study is shown by a subscript number immediately following the symbol. Notably, the subscript does not have the number when only one atom of an element present in the formula. In the above example (c), the two lobes are having the same color which is for the element nitrogen and one lobe is having the color for oxygen.
Total number of lobes of nitrogen (N) = 2
Total number of lobes of oxygen (O) = 1
Chemical formula = N2O
Thus, the chemical formula of the colored lobes (c) is written.
(d)
Interpretation:
The chemical formula of each of the following is to be written. The blue spheres represent nitrogen atoms and the red spheres oxygen atoms. Oxygen is written last in the formulas that include oxygen.
Concept introduction:
The particle of an element or compound in the written format is denoted by the chemical formulas. The symbols of elements in a particular substance covers the formula of the required substance.
Answer to Problem 1E
The chemical formula of (d) is written as N2O4
Explanation of Solution
Generally, in a formula, the total number of atoms of the element under study is shown by a subscript number immediately following the symbol. Notably, the subscript does not have the number when only one atom of an element present in the formula. In the above example (d), the two lobes are having the same color which is for the element nitrogen and other four lobes are having the color for oxygen.
Total number of lobes of nitrogen (N) = 2
Total number of lobes of oxygen (O) = 4
Chemical formula = N2O4
Thus, the chemical formula of the colored lobes (d) is written.

- Decide whether each of the molecules in the table below is stable, in the exact form in which it is drawn, at pH = 12. If you decide at least one molecule is not stable, then redraw one of the unstable molecules in its stable form below the table. (If more than one molecule is unstable, you can pick any of them to redraw.)
