The specific heat capacity of water is 4.18 Jg-1 0C-1 and the specific heat capacity of liquid hexane (C6H14) is 2.29 Jg-1 0C-1. Explain, in terms of bonding, why the specific heat capacity of water is so much higher than that of hexane. Your answer should include a diagram showing the structure of two water molecules with the bond types within each molecule and between two molecules, clearly labelled

The atomic radius of sodium is 186 pm and of chlorine is 100 pm. the ionic radius for na+ is 102 pm and for cl– is 181 pm. in going from na to cl in period 3, why does the atomic radius decrease while the ionic radius increases? a. the inner electrons in the sodium cation shield its valence electrons more effectively than the inner electrons in the chloride anion do. b. the inner electrons shield the valence electrons more effectively in the chlorine atom than in the chloride anion. c. the outermost electrons in chloride experience a smaller effective nuclear charge than those in the sodium cation do. d. the outermost electrons in chloride experience a larger effective nuclear charge than those in the sodium cation do. e. monatomic ions are bigger than the atoms from which they are formed.
