Chapter 2: Problem 31

Identify the following as elements or compounds: \(\mathrm{NH}_{3}, \mathrm{~N}_{2}, \mathrm{~S}_{8}, \mathrm{NO}, \mathrm{CO}, \mathrm{CO}_{2}, \mathrm{H}_{2}, \mathrm{SO}_{2}\)

Short Answer

Expert verified
The identified elements are \(N_2, S_8, H_2\) and the identified compounds are \(NH_3, NO, CO, CO_2, SO_2\).

Step by step solution

01

Identify elements

Elements consist of only one type of atom. Identify the chemical formulas that consist of only one type of atom, i.e., formulas where the only variation is the number of atoms (subscript in the formula). Only \(N_2, S_8, H_2\) contain single types of atoms, so they are elements.
02

Identify compounds

Compounds consist of different types of atoms chemically bonded together. The remaining chemical formulas represent compounds, which are \(NH_3, NO, CO, CO_2, SO_2\). These formulas contain more than one type of atom, therefore, they are compounds.
