Chapter 3, Problem 27QAP
Small amounts of tungsten (W) are usually added to steel to strengthen and harden the steel. Two ores of tungsten are ferberite (FeWO4) and scheelite (CaWO4). How many grams of FeWO4 would contain the same mass of tungsten that is present in 725 g of CaWO4?

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 2 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.
