Let me see the paper
I’m good with DNA hehehehe
Answer:
Explanation:
Intermolecular forces are the forces that hold the molecules together in a substance. The state in which this substance will be at normal atmospheric conditions, and other physical properties such as boiling and melting points, are a consequence of the intermolecular forces.
The type of intermolecular force that happens in nonpolar compounds is dispersion forces. The atom or nonpolar molecule will be disturbed by the proximity of an ion or a polar molecule, thus shifting its electron cloud. The atom or nonpolar molecule will be an induced dipole.
In these tetrahedral molecules, which are not polar, the attractive forces will be London forces, which arise as a consequence of temporary induced dipoles.
Since these forces depend on proximity (the closer the proximity the larger the attraction) <u>those molecules with a higher molar mass will have a larger electron cloud, which will be more susceptible to the effect of an induced dipole in the surroundings</u> (the electrons are on the outer layers will be less attracted by the nuclei).
CF₄ > CCl₄ > CBr₄ >Cl₄
--------------------------------> Increasing size
--------------------------------> Increasing melting point
The melting point increases as the molecules get bigger, that is, as the number of molecules in the molecule increases.
Schrödinger found the quantum mechanical model of the atom after Bohr’s model.
It is better than Bohr’s model because you can use mathematical equations to find electrons certain position. Unlike Bohr’s which is just a “cloud” where the an electron could possibly be.
Something that can not be undone. Like baking bread..cant be undone.
Answer:
Because Rutherford's model was weak on the position of the electrons, Bohr focused on them. He hypothesized that electrons can move around the nucleus only at fixed distances from the nucleus based on the amount of energy they have. ... However, an electron could never exist in between two energy levels
