H-bonding is the principle IMF holding the protein strands together. b) Kr A cubic unit cell contains manganese ions at the corners and fluoride ions at the center of each edge. These intermolecular forces are of comparable strength and thus require the same amount of energy to overcome. This lower temperature will cause the physical and chemical changes involved in cooking the egg to proceed more slowly, and a longer time is required to fully cook the egg. Calculate the percentage of free space in each of the three cubic lattices if all atoms in each are of equal size and touch their nearest neighbors. The enthalpy of vaporization of [latex]\ce{CO2}(l)[/latex] is 9.8 kJ/mol. In order for a substance to enter the gas phase, its particles must completely overcome the intermolecular forces holding them together.
