A typical fat in the body is glyceryl trioleate, C 57 H 104 O 6 . When it is metabolized in the body, it combines with oxygen to produce carbon dioxide, water, and 3.022 × 10 4 kJ of heat per mole of fat. (a) Write a balanced thermochemical equation for the metabolism of fat. (b) How many kilojoules of energy must be evolved in the form of heat if you want to get rid of five pounds of this fat by combustion? (c) How many nutritional calories is this? (1 nutritional calories = 1 × 10 3 calories)

Definition Definition Transformation of a chemical species into another chemical species. A chemical reaction consists of breaking existing bonds and forming new ones by changing the position of electrons. These reactions are best explained using a chemical equation.

A student proposes the following two-step synthesis of an ether from an alcohol A:
1. strong base
A
2. R
Is the student's proposed synthesis likely to work?
If you said the proposed synthesis would work, enter the chemical
formula or common abbreviation for an appropriate strong base to use
in Step 1:
If you said the synthesis would work, draw the structure of an alcohol
A, and the structure of the additional reagent R needed in Step 2, in
the drawing area below.
If there's more than one reasonable choice for a good reaction yield,
you can draw any of them.
