Textbook Question
Chapter 21, Problem 21.76QP
As stated in the chapter, potassium superoxide (KO2) is a useful source of oxygen employed in breathing equipment. Calculate the pressure at which oxygen gas stored at 20°C would have the same density as the oxygen gas provided by KO2. The density of KO2 at 20°C is 2.15 g/cm3.

- To improve chromatographic separation, you must: Increase the number of theoretical plates on the column. Increase the height of theoretical plates on the column. Increase both the number and height of theoretical plates on the column. Increasing the flow rate of the mobile phase would Increase longitudinal diffusion Increase broadening due to mass transfer Increase broadening due to multiple paths You can improve the separation of components in gas chromatography by: Rasing the temperature of the injection port Rasing the temperature of the column isothermally Rasing the temperature of the column using temperature programming In GC, separation between two different solutes occurs because the solutes have different solubilities in the mobile phase the solutes volatilize at different rates in the injector the solutes spend different amounts of time in the stationary phasearrow_forwardplease draw and example of the following: Show the base pair connection(hydrogen bond) in DNA and RNAarrow_forwardNaming and drawing secondary Write the systematic (IUPAC) name for each of the following organic molecules: CH3 Z structure CH3 CH2 CH2 N-CH3 CH3-CH2-CH2-CH-CH3 NH CH3-CH-CH2-CH2-CH2-CH2-CH2-CH3 Explanation Check ☐ name ☐ 2025 McGraw Hill LLC.

- C This question shows how molecular orbital (MO) theory can be used to understand the chemical properties of elemental oxygen O₂ and its anionic derivative superoxide Oz. a) Draw the MO energy diagram for both O2 and O2. Clearly label your diagram with atomic orbital names and molecular orbital symmetry labels and include electrons. Draw the Lewis structure of O2. How does the MO description of O2 differ from the Lewis structure, and how does this difference relate to the high reactivity and magnetic properties of oxygen? ) Use the MO diagram in (a) to explain the difference in bond length and bond energy between superoxide ion (Oz, 135 pm, 360 kJ/mol) and oxygen (O2, 120.8 pm, 494 kJ/mol).arrow_forwardPlease drawarrow_forward-Page: 8 nsition metal ions have high-spin aqua complexes except one: [Co(HO)₁]".
