#98
96. How much heat in kilojoules is required to warm 10.0 g 0 of ice, initially at -10.0 °C, to steam at 110.0 °C? The specific heat capacity of ice is 2.09 J/g °C and that of steam is 1.84 J/g °C. 98. Draw a Lewis structure for each molecule and determine its molecular geometry. What kind of intermolecular forces are present in each substance? (a) BCI3 (remember that B is a frequent exception to the octet rule) vsl nss (b) HCOH (carbon is central; each H and O bonded di- rectly to C) (c) CS2 (d) NC13 Jots bor 100. Draw ionic Lewis structures for KF and CaO. Use the in- formation and the method in the previous problem to pre- dict which of these two ionic solids has the higher melting point. 102. Explain the observed trend in the boiling points of the compounds listed. Why is H,O atypical? Compound Boiling Point H2Te -2 °C H2Se -41.5 °C H2S -60.7 °C H20 +100 °C
