The validation about the structure of amino alcohol, ethanolamine has to be predicted. Concept introduction: In glycerophospholipid, the alcohol esterified to the phosphate group is an amino alcohol. The amino alcohol, ethanolamine is a primary ammonium ion, which belongs to the phosphatidylethanolamines.

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.

You're competing on a Great British television game show, and you need to bake a
cake. The quantity for each ingredient is given in grams, but you haven't been
given a kitchen scale.
Which of these properties would correlate with the mass of a baking ingredient like
eggs or milk? Check all that apply.
depth of color
viscosity
volume
density
