Which of the following molecules would you expect to have a dipole moment of zero? a, CH2 Ch3 bH2C=0
cCH2cl
dNH3​

The molecule is expected to have a dipole moment of zero.

Explanation:

The product of magnitude of the charge calculated in electrostatic units is called dipole moment.

Formula for dipole moment is as follows.

Dipole moment = Charge (in esu) distance (in cm)

Non-polar molecules have zero dipole moment.

For example, is a non-polar molecule so its dipole moment is zero.

is a polar molecule so it will have dipole moment.

is a polar molecule so it will have dipole moment.

has nitrogen atom as more electronegative than hydrogen atom. So, net dipole moment will be in the direction of nitrogen atom.

Thus, we can conclude that the molecule is expected to have a dipole moment of zero.

a non redox reaction occurs when there is not a transfer of electrons. for redox reactions, which are reduction-oxidation reactions, a change in the oxidation number occurs. elements that are reduced gain electrons, and elements that are oxidized lose electrons.

explanation:

answer: the rate of diffusion increases with increase in temperature.

increase in temperature, increases the molecular/particles speed (kinetic energy. diffusion means movement of particles through the material.

generally, the heavier the particle the more it interacts with the environment and more the temperature matters. so higher temperature results in higher diffusion.
