These bonds are often polar, due to the central and peripheral atoms having different electronegativity values. Each polar covalent bond has its own dipole moment represented as a vector. A polar molecule contains a certain geometry that does not cancel out these polar bond vectors. Therefore, ...
Identify the bonds in the mentioned molecule as covalent, polar covalent, or ionic. SiH4 Which atom is most likely to form three covalent bonds? (a) Si (b) C (c) P (d) S. Are the bonds in the compound NF3 polar covalent, nonpolar covalent, or lar...
The shape index of cells was calculated from their area A and perimeter P by the equation 4π × A/P2, where the shape index of a circle is 1. The shape index decreases as the profile becomes more elongated or irregular. The area and perimeter of 100 intercellular openings between the ...
The predominant enzymatic activity of α-amylases is the hydrolysis of α-1,4 bonds within starch molecules. The catalytic reaction first involves a glycosylation step resulting in covalent enzyme–substrate intermediate, which is subsequently hydrolyzed by a water molecule in a deglycosylation step, ...
