Concept explainers
(a)
Interpretation:
The compound having highest melting point should be determined.
Concept introduction:
The binary hydrides are compounds which contain hydrogen and one other element. Binary hydrides can be classified as ionic, covalent or metallic. Covalent hydrides have lowest melting and boiling points because they have relatively weak intermolecular forces between molecules. Ionic hydrides have higher boiling and melting points, because they have stronger ionic interactions between molecules.
(b)
Interpretation:
The compound having lowest boiling point should be determined.

- Give examples of two basic oxides. Write equations illustrating the formation of each oxide from its component elements. Write another chemical equation that illustrates the basic character of each oxide.arrow_forwardWhat mass of CaH2 is necessary to react with water to provide enough hydrogen gas to fill a balloon at 20 C and 0.8 arm pressure with a volume of 4.5 L? The balanced equation is: CaH2(s)+2H2O(l)Ca(OH)2(aq)+2H2(g)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
- Selenium is prepared by the reaction of H₂SeO₃ with gaseous SO₂. (a) What redox process does the sulfur dioxide un-dergo? What is the oxidation state of sulfur in the product? (b) Given that the reaction occurs in acidic aqueous solution,what is the formula of the sulfur-containing species? (c) Write the balanced redox equation for the processarrow_forwardHow do Groups 1A(1) and 2A(2) compare with respect to reaction of the metals with water?arrow_forwardWhat is the formal oxidation state of chlorine in ammonium perchlorate, NH4ClO4?arrow_forward
- Nitric acid forms an oxide of nitrogen on reaction with P4O10. Write the reaction involved. Also write the resonating structures of the oxide of nitrogen formed.arrow_forwardWrite a molecular formula for each compound, and indicatethe oxidation state of the group 5A element in eachformula: (a) phosphorous acid, (b) pyrophosphoricacid, (c) antimony trichloride, (d) magnesium arsenide,(e) diphosphorus pentoxide, (f) sodium phosphate.arrow_forward
