Chapter 2: Problem 37

Give an example of a case in which two molecules have different molecular formulas but the same empirical formula.

Short Answer

Expert verified
Two examples of molecules with different molecular formulas but the same empirical formula are ethyne (C2H2) and benzene (C6H6). Both have the empirical formula CH.

Step by step solution

01

Identify possible empirical formulas

Begin by thinking of a simple empirical formula. For instance, the empirical formula CH can be used.
02

Formulate different molecular formulas from the empirical formula

Next, concoct two different molecular formulas from the selected empirical formula. Remember that molecular formulas are multiples of empirical formulas. So, from CH, possible molecular formulas could be C2H2 (ethyne) and C6H6 (benzene). Both of these molecules have different molecular formulas but share the same empirical formula, CH.

Most popular questions from this chapter

Define these terms: (a) atomic number, (b) mass number. Why does a knowledge of atomic number enable us to deduce the number of electrons present in an atom?

On p. 30 it was pointed out that mass and energy are alternate aspects of a single entity called massenergy. The relationship between these two physical quantities is Einstein's famous equation, \(E=m c^{2}\), where \(E\) is energy, \(m\) is mass, and \(c\) is the speed of light. In a combustion experiment, it was found that \(12.096 \mathrm{~g}\) of hydrogen molecules combined with \(96.000 \mathrm{~g}\) of oxygen molecules to form water and re- leased \(1.715 \times 10^{3} \mathrm{~kJ}\) of heat. Calculate the corresponding mass change in this process and comment on whether the law of conservation of mass holds for ordinary chemical processes. (Hint: The Einstein equation can be used to calculate the change in mass as a result of the change in energy. \(1 \mathrm{~J}=1 \mathrm{~kg} \mathrm{~m}^{2} / \mathrm{s}^{2}\) and \(\left.c=3.00 \times 10^{8} \mathrm{~m} / \mathrm{s} .\right)\)

(a) Which elements are most likely to form ionic compounds? (b) Which metallic elements are most likely to form cations with different charges?

Group these elements in pairs that you would expect to show similar chemical properties: \(\mathrm{K}, \mathrm{F}, \mathrm{P}, \mathrm{Na}, \mathrm{Cl}\) and \(N\).

Give the number of protons and electrons in each of the following common ions: \(\mathrm{K}^{+}, \mathrm{Mg}^{2+}, \mathrm{Fe}^{3+}, \mathrm{Br}^{-},\) \(\mathrm{Mn}^{2+}, \mathrm{C}^{4-}, \mathrm{Cu}^{2+}\)
