Textbook Question
Chapter 8, Problem 8.77APP
A weather balloon is partially filled with Helium to allow for expansion at high altitudes. At STP, A weather balloon is filled with enough helium to give a volume of 25.0 L. At an altitude of 30.0 km and-35 °C, it has expanded to 2460 L. The increase in volume causes it to burst and a small parachute returns the instruments to earth. (8.5, 8.6)
- How many grams of helium are added to the balloon?
- What is the final pressure in millimeters of mercury, of the helium inside the balloon when it bursts?

What would happen if the carboxylic acid and alcohol groups were on the same molecule? In
essence, the molecule reacts with itself. Draw the structure of the products formed in this manner
using the reactants below. If two functional groups interact with one another on the same molecule,
this is called an “intramolecular" (within one) rather than "intermolecular" (between two or more)
attack.
