C) powdered sugar in hot water because the sugar is already broken so it would be more faster than sugar cube in hot water
Answer:
C. 662.60
Explanation:
the mass of Mn is about 54 grams/mol, (multiply that by 2 since there are 2 Mn's).
the mass of Se is about 79 grams/mol, so multiply that by 7
if you add them, you get 662.60 (approxamitly)
Answer:
transmutation, conversion of one chemical element into another. A transmutation entails a change in the structure of atomic nuclei and hence may be induced by a nuclear reaction (q.v.), such as neutron capture, or occur spontaneously by radioactive decay, such as alpha decay and beta decay .
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.
Since Seismic waves travel at different speeds according to type, the speed of seismic waves from fastest to slowest is option C: P waves, S waves, L waves.
<h3>Which seismic waves are moving more quickly?</h3>
P waves leave the earthquake first and go the furthest. Rock oscillates perpendicular to the direction of wave propagation in S or shear waves. In rock, S waves typically move at a pace of roughly 60% that of P waves, and they always come after the latter.
Therefore, if we examine a seismogram, we anticipate that the P-wave, which is the quickest wave, will arrive first, followed by the S-wave and then the Love and Rayleigh waves, which are the slowest waves.
