(a)
Interpretation:
The element that has the highest ionization energy should be identified from
Concept introduction:
The ionization energy of an atom defined as the energy required to remove the outermost, loosely bound electron from an isolated atom in a gaseous state.
(b)
Interpretation:
The element that has the most metallic character should be identified from
Concept introduction:
The metallic character of an element is the ability to lose an electron.
(c)
Interpretation:
Semiconductor should be identified from
Concept introduction:
Elements that have a conductivity in between conductors and no conductors are considered as the semi conductors. There are semiconducting elements and compounds.
(d)
Interpretation:
The element that forms
Concept introduction:
The number of electrons an element can removed is the charge on its anion. After the removal of electron from the atom of an element, the atom becomes negative charge and the charge on the atom is equal to the number of electrons removed from it.

- The amount of sodium hypochlorite in a bleach solution can be determined by using a given volume of bleach to oxidize excess iodide ion to iodine; ClO- is reduced to Cl-. The amount of iodine produced by the redox reaction is determined by titration with sodium thiosulfate, Na2S2O3; I2 is reduced to I-. The sodium thiosulfate is oxidized to sodium tetrathionate, Na2S4O6. In this analysis, potassium iodide was added in excess to 5.00 mL of bleach (d=1.00g/cm3) . If 25.00 mL of 0.0700 M Na2S2O3 was required to reduce all the iodine produced by the bleach back to iodide, what is the mass percent of NaClO in the bleach?arrow_forwardXenon trioxide, XeO3, is reduced to xenon in acidic solution by iodide ion. Iodide ion is oxidized to iodine, I2. Write a balanced chemical equation for the reaction.arrow_forwardPhosphorous acid, H3PO3, is oxidized to phosphoric acid, H3PO4, by nitric acid, which is reduced to nitrogen monoxide, NO. Write the balanced equation for this reaction.arrow_forward
- 8.96 A business manager wants to provide a wider range of p- and n-type semiconductors as a strategy to enhance sales. You are the lead materials engineer assigned to communicate with this manager. How would you explain why there are more ways to build a p-type semiconductor from silicon than there are ways to build an n-type semiconductor from silicon?arrow_forwardAlumina, Al2O3, is amphoteric. Among examples of its amphoteric character are the reactions that occur when Al2O3 is heated strongly or fused with acidic oxides and basic oxides. (a) Write a balanced equation for the reaction of alumina with silica, an acidic oxide, to give aluminum metasilicate, Al2(SiO3)3. (b) Write a balanced equation for the reaction of alumina with the basic oxide CaO to give calcium aluminate, Ca(AlO2)2.arrow_forwardAluminum is produced commercially by the electrolysis of Al2O3 in the presence of a molten salt. If a plant has a continuous capacity of 1.00 million A, what mass of aluminum can be produced in 2.00 h?arrow_forward
- Sodium perchlorate, NaClO4, is produced by electrolysis of sodium chlorate, NaClO3. If a current of 2.50 103 A passes through an electrolytic cell, how many kilograms of sodium perchlorate are produced per hour?arrow_forwardThe amount of sodium hypochlorite in a bleach solution can be determined by using a given volume of bleach to oxidize excess iodide ion to iodine, because the reaction goes to completion. The amount of iodine produced is then determined by titration with sodium thiosulfate, Na2S2O3, which is oxidized to sodium tetrathionate, Na2S4O6. Potassium iodide was added in excess to 5.00 mL of bleach (density = 1.00 g/mL). This solution, containing the iodine released in the reaction, was titrated with 0.100 M Na2S2O3. If 34.6 mL of sodium thiosulfate was required to reach the endpoint (detected by disappearance of the blue color of the starch iodine complex), what was the mass percentage of NaClO in the bleach?arrow_forward
