Question

Compounds can rotate around bonds and form different shapes - different conformations.
The shape that the molecule is most likely to assume is influenced by the strain. Strain increases the energy of a
different conformation.
A compound can experience three different types of strain: angular strain, torsional strain, and steric strain. Due to the
interactions and repulsions between different molecules, a compound can consist of any, all, or none of these three strains.
Steric strain is seen when different atoms within a structure are bumping into each other.

Archimedes tells us the lifting power of a balloon (how much mass it can lift) is equal to the difference between the mass of the balloon and the mass of the air it displaces. That is, if the balloon occupies the same volume as 10 kg of air, but the balloon only weighs 2 kg, then the gas density kg 0.090 3 m H, balloon can lift 8 kg. Airships have sometimes been filled with hydrogen (H,), but hydrogen is very flammable, and kg 0.18 Не m after the Hindenburg caught fire and crashed in 1937 with serious loss of life airships have nearly always been filled with helium (He) instead. kg 1.23 3 m' air Suppose a new airship Star of Balogna will have the shape of a cylinder 100. m long, with a radius of 15.0 m, and will weigh 9400. kg without any gas inside it. Suppose also the average passenger weighs 81 kg. Calculate how many passengers the Balogna could carry if it were filled with hydrogen, and also if it were filled with helium.
