Determine whether each of the molecules below is polar or nonpolar. Tetrahedral C C l 4 CClX4 Nonpolar Tetrahedral C H 3 O H CHX
liraira [26]

Answer:

CCl4 - Nonpolar

CH3OH - polar

NH3 - polar

CS2 - Nonpolar

Explanation:

One important thing that we should know is that polarity has to do with the presence of a resultant dipole moment in a molecule.

Dipole moment is a vector quantity, This means that its direction is also taken into account when discussing the dipole moment of molecules.

Hence, symmetrical molecules such as CS2 and CCl4 are non-polar even though they have polar bonds because their dipoles cancel out(zero resultant dipole moment).

On the other hand, NH3 and CH3OH are non-symmetrical molecules hence they possess an overall dipole moment and are polar molecules.

Most continuous spectra are examples of what we also call thermal radiation spectra. Why do we call them "thermal" spectra?
lisov135 [29]

Answer:

They are emitted from heated objects

Explanation:

When objects are heated, they emit light at all wavelengths thereby forming a continuous spectrum. Electromagnetic radiation of all wavelengths and colours are usually represented in such spectrum. A thermal spectrum is quite a simple spectrum since it depends on temperature.
