molecules. Water is unique in that it has a high surface tension compared to other liquids. Water is formed when two hydrogen atoms and one oxygen . atom share electrons. This is called covalent bonding. Because of the bent structure of the H2O molecule, the molecule has a slightly negative charge Straight chain molecules have more places along its length where they can be attracted to other molecules, so there are more chances of London Dispersion Forces to be developed. Hence, they have stronger intermolecular forces as compared to the branched chain molecules which have a compact shape, therefore fewer spaces where they can be ...

A molecule with the formula AB 3, in which A and B represent different atoms, could have one of three different shapes. Sketch and name the three different shapes that this molecule might have. Water's polarity is caused by the bent geometric shape of the water molecule, and the covalent bonds between the oxygen and 2 hydrogen atoms.
Example 2. In the ammonia, NH 3, molecule the three N–H bonds have only a slight polarity (toward the more electronegative nitrogen atom).

  • Manta submit businessDec 21, 2020 · We study each shape by considering traces, that is, intersections of each surface with a plane parallel to a coordinate plane. For instance, consider the elliptic paraboloid \(z= x^2/4+y^2\), shown in Figure 10.13. If we intersect this shape with the plane \(z=d\) (i.e., replace \(z\) with \(d\)), we have the equation: \[d = \frac{x^2}4+y^2.\]
