The reason for HF (hydrogen fluoride), NH 3 (ammonia), and H 2 O (water) to be able toform hydrogen bondswhile methane fails to do so, although all these elements are present in the second row of the periodic table and are sp3hybridized. Introduction: A hydrogen bond is formed when an H-atom(hydrogen atom) binds with a highlyelectronegative ato, mr there is a lone pair of electronspresent in thevicinity. Hydrogen bonds are weaker than covalent and ionic bonds, but stronger than dipole–dipole interactions.

9) Below, there is a representation of an SDS-PAGE gel. Assuming the samples in the MW standard have masses of: 66 kDa, 45 kDa, 36 kDa, 29 kDa, 24 kDa, 20.1 kDa, and 14.2 kDa, a) Figure 4: indicate where each of the measurements were taken and label as in II.6. figure 2 above. b) As in II.7. Table 1 above create Table 2 using the data below. Determine the r.f. values for the MW standards, plot the relative mobility versus the log of the mass for the standards, and use the best fit straight line to determine the molecular weights of the proteins in the whey, peak 1, and peak 2 lanes.
