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 balloon can lift 8 kg. Airships have sometimes been filled with hydrogen (H₂), but hydrogen is very flammable, and after the Hindenburg caught fire and crashed in 1937 with serious loss of life airships have nearly always been filled with helium (He) instead. Passengers with H₂: Passengers with He: gas 0 H₂ He air density 0.090 0.18 1.23 kg 3 m kg 3 m kg 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 9250. kg without any gas inside it. Suppose also the average passenger weighs 82 kg. Calculate how many passengers the Balogna could carry if it were filled with hydrogen, and also if it were filled with helium. m

The ionization energy of an alkali metal is reflected in its reaction with water, where a bigger explosion indicates an easier reaction. In general, if X is an alkali metal, the reaction with water is: X(s) + H2O (l) = XOH (aq) + H2 (g) What type of reaction is this?
