Arsenic reacts with oxygen to form oxides analogous to the phosphorus oxides. These arsenic oxides react with water similarly to the phosphorus oxides. Write balanced chemical equations describing the reaction of arse-nic with oxygen and the reaction of the oxides with water.
Answer to relevant QuestionsCompare the description of the localized electron model (Lewis structure) with that of the molecular orbital model for the bonding in NO, NO+, and NO-. Account for any discrepancies between the two models. The space shuttle orbiter utilizes the oxidation of methyl-hydrazine by dinitrogen tetroxide for propulsion: 4N2H3CH3(l) + 5N2O4(l) → 12H2O(g) + 9N2(g) + 4CO2(g) Calculate ΔHo for this reaction using data in Appendix 4. In large doses, selenium is toxic. However, in moderate intake, selenium is a physiologically important element. How is selenium physiologically important? Photogray lenses contain small embedded crystals of solid silver chloride. Silver chloride is light-sensitive because of the reaction AgCl(s) → Ag(s) + Cl(s) Small particles of metallic silver cause the lenses to darken. ...Diagonal relationships in the periodic table exist in addi-tion to the vertical relationships. For example, Be and Al are similar in some of their properties, as are B and Si. Rationalize why these diagonal relationships ...
