a. The structure of the bicarbonate (hydrogen carbonate) ion, HCO3-, HCO3 " is best described as a hybrid of several contributing resonance forms, two of which are shown here. HO :0: HO + :Ö: Bicarbonate is crucial for the control of body pH (for example, blood pH 7.4). A more self-indulgent use is in baking soda, where it serves as a source of CO2 CO2 gas, which gives bread and pastry their fluffy constituency. (i) Draw at least one additional resonance form. = (ii) Using curved "electron-pushing" arrows, show how these Lewis structures may be interconverted by movement of electron pairs. (iii) Determine which form or forms will be the major contributor(s) to the real structure of bicarbonate, explaining your answer on the basis of the criteria in Section 1-5.

Calibri 11 + BIL NAME: Jaylena M A student is investigating the ctect of volume on pressure during a lab activity. The student uses the following volumes (mL). 12, 13, 14, 16, 17, 18, 19, 20, 21, 22, 23, 24, 26, 28, 30, 33, 34, 35, 38, 40, 42, 44. 46, and 50. As the volume changed they measured the following pressures (atm) 11.0, 10.5, 10.0, 9.2. 8.5, 78, 75, 7.0, 6.8, 6.5, 6.0, 5.9, 5.5, 5.0, 4.8, 4.5, 4.2, 3.9, 3.8, 3.5, 3.3, 3.2, 3.0, 2.9.
