Chapter 3: Problem 62

Write formulas for the compounds: (a) magnesium perchlorate; (b) lead(II) acetate; (c) tin(IV) oxide; (d) hydroiodic acid; (e) chlorous acid; (f) sodium hydrogen sulfite; (g) calcium dihydrogen phosphate; (h) aluminum phosphate; (i) dinitrogen tetroxide; (j) disulfur dichloride.

Short Answer

Expert verified
The formulas for the compounds are: (a) Mg(ClO4)2; (b) Pb(C2H3O2)2; (c) SnO2; (d) HI; (e) HClO2; (f) NaHSO3; (g) Ca(H2PO4)2; (h) AlPO4; (i) N2O4; (j) S2Cl2.

Step by step solution

01

Finding the formula for Magnesium perchlorate

Magnesium is a metal and perchlorate is a polyatomic ion. This makes Magnesium perchlorate an ionic compound. Magnesium has a +2 charge and perchlorate has a -1 charge. Balancing the charges gives Mg(ClO4)2.
02

Finding the formula for Lead(II) acetate

Lead(II) indicates that Lead has a +2 charge. Acetate is a polyatomic ion with a -1 charge. Balancing the charges gives Pb(C2H3O2)2.
03

Finding the formula for Tin(IV) oxide

Tin(IV) means Tin has a +4 charge. Oxide has a -2 charge. Balancing the charges gives SnO2.
04

Finding the formula for Hydroiodic acid

In acids, the 'hydro' prefix indicates that it is a binary acid, and the 'ic' suffix indicates that it has more oxygen atoms. Hydroiodic acid becomes HI.
05

Finding the formula for Chlorous acid

The root 'chlor' indicates that Chlorine is involved, and the 'ous' suffix indicates that it has fewer oxygen atoms. Chlorous Acid is HClO2.
06

Finding the formula for Sodium hydrogen sulfite

Sodium has a +1 charge, and Hydrogen sulfite (HSO3) has a -1 charge. Balancing the charges gives NaHSO3.
07

Finding the formula for Calcium dihydrogen phosphate

Calcium has a +2 charge and Dihydrogen phosphate (H2PO4) has a -1 charge. Balancing the charges gives Ca(H2PO4)2.
08

Finding the formula for Aluminum phosphate

Aluminum has a +3 charge, and Phosphate has a -3 charge. Balancing the charges gives AlPO4.
09

Finding the formula for Dinitrogen tetroxide

In molecular compounds, prefixes indicate the number of atoms. So, 'di' stands for 2 and 'tetra' stands for 4. Therefore, Dinitrogen tetroxide becomes N2O4.
10

Finding the formula for Disulfur dichloride

In molecular compounds, prefixes indicate the number of atoms. So, 'di' stands for 2. Therefore, Disulfur dichloride becomes S2Cl2.

Liquid ethyl mercaptan, \(\mathrm{C}_{2} \mathrm{H}_{6} \mathrm{S},\) has a density of \(0.84 \mathrm{g} / \mathrm{mL} .\) Assuming that the combustion of this compound produces only \(\mathrm{CO}_{2}, \mathrm{H}_{2} \mathrm{O},\) and \(\mathrm{SO}_{2},\) what masses of each of these three products would be produced in the combustion of \(3.15 \mathrm{mL}\) of ethyl mercaptan?

The insecticide dieldrin contains carbon, hydrogen, oxygen, and chlorine. When burned in an excess of oxygen, a 1.510 g sample yields \(2.094 \mathrm{g} \mathrm{CO}_{2}\) and \(0.286 \mathrm{g} \mathrm{H}_{2} \mathrm{O} .\) The compound has a molecular mass of 381 u and has half as many chlorine atoms as carbon atoms. What is the molecular formula of dieldrin?

A 0.622 g sample of a metal oxide with the formula \(\mathrm{M}_{2} \mathrm{O}_{3}\) is converted to \(0.685 \mathrm{g}\) of the sulfide, MS. What is the atomic mass of the metal M?

To deposit exactly one mole of \(\mathrm{Ag}\) from an aqueous solution containing \(\mathrm{Ag}^{+}\) requires a quantity of electricity known as one faraday (F). The electrodeposition requires that each \(\mathrm{Ag}^{+}\) ion gain one electron to become an Ag atom. Use appropriate physical constants listed on the inside back cover to obtain a precise value of the Avogadro constant, \(N_{A}\).

The element \(X\) forms the chloride \(X C l_{4}\) containing \(75.0 \% \mathrm{Cl},\) by mass. What is element \(\mathrm{X} ?\)
