Answer to Problem 1PE
The chemical formula of the compound is C2H6O
Explanation of Solution
The chemical compounds are made up of polyatomic ions and the ratio of positive to negative ions present in the substance is expressed as formula of ionic compound. In the above example, the black spheres represent carbon atoms; the red, oxygen atoms; and the white represents hydrogen atoms. From the diagram, we come to know that,
Number of carbon atoms = 2
Number of hydrogen atoms = 6
Number of oxygen atom = 1
Thus, the molecular formula is C2H6O
Thus, the chemical formula of compound (a) is written.
(b)
Interpretation:
The chemical formula of each of the following is to be written. In parts b, the black spheres represent carbon atoms; the red, oxygen atoms; and the white, hydrogen atoms.
Concept introduction:
The particles possessing by chemical compounds are usually represented by chemical formulas. Besides, the chemical formula of a substance is having the symbols of element using which the chemical compound is made. Generally, in a chemical formula, the subscript number after a symbol denotes the number of atoms of the element in the formula unit of the substance. If the compound is having only one atom of an element of interest, the subscript is omitted.
