A chemist has two lasers, Laser-A and Laser-B. It is observed that the two lasers emit visible light and that the wavelength of the light emitted by Laser-A is half as long as the wavelength of the light emitted
by Laser B. Which of the following statements could possibly be true?
(a) Laser-B will have photons that are twice as energetic as those of Laser-A.
(b) The frequency of the photons emitted by Laser-B will be twice that of the photons emitted by LaserA.
(c) Laser-A emits red light and Laser-B emits yellow light.
(d) All of these statements could possibly be true.
(e) none of these statements could possibly be true

vanderwaal's forces of attraction are the electrostatic intermolecular forces that exist in a molecule due to the temporary or permanent dipoles that are developed in a molecule. in , the major intermolecular forces are dipole-dipole interactions as the molecule is polar (bent structure). so the vanderwaal's forces of interaction in between molecules are the permanent dipole-dipole interactions that develop due to the dipole that exists in between the polar h - s bond. the positively charged hydrogen atom is attracted towards the negative end of the dipole that is sulfur of the adjacent molecule. therefore, these forces of attraction are relatively stronger than that of london dispersion forces that exist in non polar molecules.

a small container that holds a source of energy a solar cell that captures light energy and converts it into electricity a voltaic cell that uses the oxidation of a fuel to produce electricity

explanation:

i believe that it is a exoplanet

answer:

the reaction is type of combination reaction.

explanation:

on the product side, there are 2 molecules of bonded to fe   which means one atom of fe are combined two molecules of . so, balanced chemical equation becomes :

this reaction follows the reaction type of combination reaction. a combination reaction is defined as chemical reaction in which reactants combines together to form a single product.
