Concept explainers
Interpretation:
The benefit and limitation of using metallic Gallium in thermometer should be explained.
Concept Introduction:
Group 3A, boron family, in this group contain a metalloid, boron and
The elements of group 3A boron, aluminium, gallium, indium and thallium are the first of the p-block elements and have the valence electronic configuration
The 3A boron family except for boron, which is a metalloid (or) semimetal the group 3A elements are silvery metals and good conductors of electricity. Aluminium is the most important element of this group because it is use in making aircraft, electrical transmission lines, cooking utensils, sodacans and numerous other commercial products.

General Chemistry: Atoms First
- Aluminum 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_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; 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_forward
