Chapter 4: Problem 38

(a) Without referring to Figure \(4.11,\) give the oxidation numbers of the alkali and alkaline earth metals in their compounds. (b) Give the highest oxidation numbers that the Groups \(3 \mathrm{~A}-7 \mathrm{~A}\) elements can have.

Short Answer

Expert verified
The oxidation numbers for alkali and alkaline earth metals in their compounds are +1 and +2 respectively. The highest oxidation numbers for the Groups 3A to 7A elements are +5, +4, +3, +2, +1, 0, and -1 respectively.

Step by step solution

01

Identify Alkali and Alkaline Earth Metals' Oxidation Numbers

The alkali metals are in group 1 of the periodic table and have an oxidation number of +1 in their compounds. The alkaline earth metals are in group 2 and have an oxidation number of +2 in their compounds.
02

Identify Oxidation Numbers for Groups 3A-7A Elements

The highest oxidation numbers for elements in groups 3A-7A can be determined by the group number. Subtract the group number from 8 to find the highest oxidation number. So, the highest oxidation numbers for groups 3A-7A are +5, +4, +3, +2, +1, 0, and -1 respectively.

A 3.664 -g sample of a monoprotic acid was dissolved in water. It took \(20.27 \mathrm{~mL}\) of a \(0.1578 \mathrm{M}\) \(\mathrm{NaOH}\) solution to neutralize the acid. Calculate the molar mass of the acid.

Describe the laboratory preparation for the following gases: (a) hydrogen, (b) oxygen, (c) carbon dioxide, (d) nitrogen. Indicate the physical states of the reactants and products in each case. [Hint: Nitrogen can be obtained by heating ammonium nitrite \(\left(\mathrm{NH}_{4} \mathrm{NO}_{2}\right)\).]

Sodium carbonate \(\left(\mathrm{Na}_{2} \mathrm{CO}_{3}\right)\) is available in very pure form and can be used to standardize acid solutions. What is the molarity of a HCl solution if \(28.3 \mathrm{~mL}\) of the solution are required to react with \(0.256 \mathrm{~g}\) of \(\mathrm{Na}_{2} \mathrm{CO}_{3} ?\)

Calculate the molarity of each of the following solutions: (a) \(29.0 \mathrm{~g}\) of ethanol \(\left(\mathrm{C}_{2} \mathrm{H}_{5} \mathrm{OH}\right)\) in \(545 \mathrm{~mL}\) of solution, (b) \(15.4 \mathrm{~g}\) of sucrose \(\left(\mathrm{C}_{12} \mathrm{H}_{22} \mathrm{O}_{11}\right)\) in \(74.0 \mathrm{~mL}\) of solution, (c) \(9.00 \mathrm{~g}\) of sodium chloride \((\mathrm{NaCl})\) in \(86.4 \mathrm{~mL}\) of solution.

A 22.02-mL solution containing \(1.615 \mathrm{~g} \mathrm{Mg}\left(\mathrm{NO}_{3}\right)_{2}\) is mixed with a 28.64-mL solution containing \(1.073 \mathrm{~g}\) \(\mathrm{NaOH}\). Calculate the concentrations of the ions remaining in solution after the reaction is complete. Assume volumes are additive.
