The definition of atomic structure is the positively charged nucleus and the negatively charged electrons circling around it, within an atom. An example of atomic structure is what gives energy to atoms and then to molecules.

Which of these are ways in which a seed might be dispersed? Check all that apply. organisms clouds wind water rocks

alisha [4.7K]

Answer: organisms

wind

water

Explanation:

There are several ways through which plants can move the seed of plants from one place to another. It isn't possible for plants to move their seeds themselves, therefore, there are other methods for their seeds to be moved.

These include fire, wind, animals, organisms, water, fire, water etc. It should be noted that rocks and clouds are not dispersion methods.

iren2701 [21]

Answer:

Polarity is a measure of molecule's electrical charge which means that molecule or it's groups can have a dipole moment and also make hydrogen bonds.

Explanation:

So in terms of polarity methanol is more polar then ethyl acetate due to it's higher dipole moment and that it is a stronger hydrogen bond acceptor and also can be a hydrogen bond donor. So if we add methanol to the elutioning system it becomes more polar because and our compound moves faster on tlc due to methanol providing some more hydrogen bonds to it and increasing dipole-dipole interactions.

1. The H atom and the Be +3 ion each have one electron. Does the Bohr model predict their spectra accurately? Would you expect t

lesantik [10]

Answer:

yes the Bohr model predicts their spectra accurately

Explanation:

The Bohr model based on one electron system

The atom H has a single atom and the ion Be+3 has a single atom as well and this proves that the Bohr model predicts their spectra accurately .

also apply the equation model to further explain

E = $\frac{-(z^2) (2.18 * 10^{-18}j) }{n^2}$

z = atomic number

for H the value of z = 1

for Be+3 the value of z = 4

when this values are substituted into the equation above

E = $\frac{-(1) (2.18 * 10^{-18}j) }{n^2}$ , E = $\frac{-(4) (2.18 * 10^{-18}j) }{n^2}$

this results show that the energy level of Be+3 is higher than the energy level of H by a factor of 16 , and this shows that their line patterns are similar
