2013年3月10日 · The dipole moment of a water molecule is 6.29E-30Cm. What is the electric potential's magnitude 1.43nm from a water molecule along the axis of the dipole? Homework Equations p = qr The Attempt at a Solution I don't have values for q or r.

2009年8月24日 · A water molecule has a dipole moment because of its bent molecular structure and the electronegativity difference between oxygen and hydrogen atoms. Oxygen is more electronegative and pulls the shared electrons closer to itself, resulting in a partial negative charge on the oxygen atom and a partial positive charge on the hydrogen atoms.

2017年4月17日 · The direction of the electric dipole moment of a water molecule is determined by the arrangement of the atoms in the molecule. The oxygen atom has a higher electronegativity than the hydrogen atoms, causing the shared electrons to be pulled towards the oxygen atom, creating a separation of charge and resulting in a dipole moment.

2008年2月27日 · The dipole moment of the water molecule H2O is 6.17x10^-30 Cm. Consider a water molecule located at the origin whose dipole moment p_vec points in the positive x direction. A chlorine ion (Cl-), of charge -1.60x10^-19 C, is located at x=3.00x10^-9 meters.

2007年1月22日 · A water molecule is a permanent dipole with a dipole moment p = qs. There is a water molecule in the air a very short distance x from the midpoint of a long rod of length L and uniform charge +Q. The axis of the rod is perpendicular to the rod. Note that s << x << L. a) Find the the force of the rod on the molecule in terms of Q, L, x, p.

2008年1月23日 · In summary, the dipole moment of a water molecule is 6.17 x 10^-30 C*m, with the positive direction pointing along the x-axis. A chlorine ion with a charge of -1.60 x 10^-19 C is located at x = 3.00 x 10^-9 m, where the separation d between the charges is much smaller.

2008年1月25日 · Consider a water molecule located at the origin whose dipole moment points in the +x-direction. A chlorine ion , of charge -1.60*10^-19, is located at x= 3.00*10^-3 m. Assume that x is much larger than the separation d between the charges in the dipole, so that the approximate expression for the electric field along the dipole axis can be used.

2021年9月26日 · A water molecule perpendicular to an electric field has 5.00×10−22 J more potential energy than a water molecule aligned with the field. The dipole moment of a water molecule is 6.2×10−30Cm. What is the strength of the …
