Textbook Question
Chapter 8.4, Problem 8.40PP
Bacteria and viruses are inactivated by temperatures above 135 °C. An autoclave contains steam at 1.00 atm and 100 °C. What is the pressure, in atmospheres, when the temperature of the steam in the autoclave reaches 135 °C, if V and n do not change?

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.

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.
