Give the systematic name for the following compounds that are found in everyday life: a. \(\mathrm{H}_{2} \mathrm{S}\) (rotten egg smell) b. \(\mathrm{SO}_{2}\) (smell of burnt matches) c. \(\mathrm{SF}_{6}\) (aerosol can propellant) d. \(\mathrm{Na}_{2} \mathrm{SO}_{3}\) (dried fruit preservative)

Short Answer

Expert verified
a. Dihydrogen monosulfide b. Sulfur dioxide c. Sulfur hexafluoride d. Sodium sulfite

Step by step solution

01

a. \(\mathrm{H}_{2} \mathrm{S}\)

This compound consists of hydrogen (H) and sulfur (S). There are 2 atoms of hydrogen and 1 atom of sulfur. The systematic name will consist of the elements' names and the number of atoms in the form of prefixes. Systematic name: Dihydrogen monosulfide
02

b. \(\mathrm{SO}_{2}\)

This compound consists of sulfur (S) and oxygen (O). There is 1 atom of sulfur and 2 atoms of oxygen. The systematic name will include the elements' names and the count of atoms in the form of prefixes. Systematic name: Sulfur dioxide
03

c. \(\mathrm{SF}_{6}\)

This compound consists of sulfur (S) and fluorine (F). There is 1 atom of sulfur and 6 atoms of fluorine. As before, the systematic name will use the elements' names and prefixes to indicate the atom counts. Systematic name: Sulfur hexafluoride
04

d. \(\mathrm{Na}_{2} \mathrm{SO}_{3}\)

This compound is an ionic compound composed of sodium (Na) and sulfate (SO\(_3\)) ions. There are 2 sodium atoms and 1 sulfate ion (with 1 sulfur and 3 oxygen atoms). For ionic compounds, we name the cation (positive ion) first and the anion (negative ion) second. Systematic name: Sodium sulfite

Most popular questions from this chapter

You have two distinct gaseous compounds made from element X and element Y. The mass percents are as follows: Compound I: \(30.43 \% \mathrm{X}, 69.57 \% \mathrm{Y}\) Compound \(\mathrm{II} : 63.64 \% \mathrm{X}, 36.36 \% \mathrm{Y}\) In their natural standard states, element X and element Y exist as gases. (Monatomic? Diatomic? Triatomic? That is for you to determine.) When you react “gas X” with “gas Y” to make the products, you get the following data (all at the same pressure and temperature): 1 volume "gas \(\mathrm{X}^{\prime \prime}+2\) volumes "gas $\mathrm{Y}^{\prime \prime} \longrightarrow$ 2 volumes compound I 2 volumes \(^{4}\) gas \(\mathrm{X}^{\prime \prime}+1\) volume "gas \(\mathrm{Y}^{\prime \prime} \longrightarrow\) 2 volumes compound II Assume the simplest possible formulas for reactants and products in the chemical equations above. Then, determine the relative atomic masses of element X and element Y.

Write the symbol of each atom using the \(\left(_{Z}^{A} X\right)\) format.

Write the formula for each of the following compounds: a. chromium(VI) oxide b. disulfur dichloride c. nickel(II) fluoride d. potassium hydrogen phosphate e. aluminum nitride f. ammonia g. manganese(IV) sulfide h. sodium dichromate i. ammonium sulfite j. carbon tetraiodide

Would you expect each of the following atoms to gain or lose electrons when forming ions? What ion is the most likely in each case? a. Ra b. In c. P d. Te e. Br f. Rb

Indium oxide contains 4.784 \(\mathrm{g}\) of indium for every 1.000 \(\mathrm{g}\) of oxygen. In \(1869,\) when Mendeleev first presented his version of the periodic table, he proposed the formula $\operatorname{In}_{2} \mathrm{O}_{3}$ for indium oxide. Before that time it was thought that the formula was InO. What values for the atomic mass of indium are obtained using these two formulas? Assume that oxygen has an atomic mass of 16.00 .
