(a)
Interpretation:
The MO band formation by individual atomic orbital should be explained, and the reason for the one-dimensional array of hydride ion to be known as electrical insulator is to be explained.
Concept introduction:
Semiconductors are devices that have conductivity intermediate between conductors and insulators and their conductivity gets enhances when doped.
Doped semiconductors are used in commercialized electronic devices as diodes, transistors, LEDs, photovoltaic cells. They all differ in their functions that are as follows:
- Diodes convert alternating current to direct current.
- Photovoltaic cells convert sunlight to electricity.
- LEDs act as a light source.
- Transistors amplify an electrical signal in an integrated circuit.
(b)
Interpretation:
If the one dimensional array of hydride ion, is doped by neutral hydrogen, then change in MO diagram and its electrical conductivity property should be explained.

- Silicic acid, SiO2.xH2O(s), is a weaker acid than carbonic acid,H2CO3(aq). Write a balanced equation for the reactionof carbonic acid with a simple silicate, such as Mg2SiO4(s). Explainhow this reaction is relevant to the reduction of atmospheric carbondioxide levels over geologic time.arrow_forwardSeveral transition metals are prepared by reduction of themetal halide with magnesium. Titanium is prepared by the Krollmethod, in which ore (ilmenite) is converted to the gaseous chlo-ride, which is then reduced to Ti metal by molten Mg. Assuming yields of 84% for step 1 and 93% for step 2,and an excess of the other reactants, what mass of Ti metal canbe prepared from 21.5 metric tons of ilmenite?arrow_forwardThe lanthanide elements reacts with oxygen to give compounds of the type Ln2O3.However,the are interesting exceptions ,such as common oxide of Terbium, TbxOy(y and x stand for unknown) 1.Given that the compound is 73.945%,what is its formula? 2.What is the oxidation number of terbium in this compound? 3.Write a balanced equation for the reaction of terbium and oxygen to give this oxide.arrow_forward

- A slag sample is known to contain all of its iron in the forms of FeO and Fe2O3. A sample of 1,000 g of the slag was dissolved in hydrochloric acid according to the usual method, then reduced with stannous chloride and finally titrated with a 0.02237 M solution of potassium permanganate, of which 28.59 mL were used. A second aliquot of the slag sample, weighing 1,500, was dissolved in a nitrogen atmosphere to further adjust the oxidation state of the iron, it was immediately titrated with the same potassium permanganate solution. If this second experiment required 15.60 mL of permanganate solution, calculate: a) The percentage of total iron in the slag. b) The percentages of the oxide FeO and Fe2O3arrow_forwardThallium forms the compound TlI₃.
