4. The common oxidation number for an alkaline earth metal is +2.
(a) Using the Born-Mayer equation (for determining the lattice enthalpy) and a Born-Haber
cycle (draw it), show that CaCl is an exothermic compound (negative AHf). Make a
reasonable prediction to estimate the ionic radius of Ca (explain your reasoning). The
sublimation (atomization) enthalpy for Ca(s) is 178 kJ/mol.
(b) Show that an explanation for the non-existence of CaCl can be found in the enthalpy
change for the reaction below. The AHf for CaCl2(s) is -190.2 kcal/mol.

The ratio in which an element will combine with oxygen is related to the ions that the element commonly forms. For example, lithium forms the Li+ ion easily (because it has a low first ionization energy, but high second ionization energy). Oxygen forms O-2 ions easily (because it has a high electron affinity for two electrons). Thus, Li+ and O-2 combine to form Li2O to become a neutral molecule. Based on this reasoning, which of the following would be the formula for magnesium oxide? Mg2O2 MgO MgO2 Mg2Oarrow_forwardArchimedes 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. marrow_forward
