<span>so I'm pretty sure that the answer is 92.70808 g/mol</span>
Answer:
A.No. Assuming no other factors (such as air resistance) the first object will have a velocity of 32 feet/second when the other is dropped. Since they will both have the same acceleration, the first distance between them will increase by 32 feet per second.
Explanation:
During a total lunar eclipse, the Moon is still visible to
the naked eye due to the fact that the atmosphere of our planet, which is Earth
bends, which results to the scattering of some sunlight, which actually reaches
the Moon during a Lunar Eclipse, which is why the Moon remains visible despite
the occurrence of a full lunar eclipse.
The electrons in an atom move around the nucleus known as electron shells. Each electron shell contains a certain number of electrons, and they are arranged in a process called atoms electric structure
Answer:
- The elements Li, C, and F, are all in the period (row) # 2 of the periodic table, and, in consequence, those atoms have two energy levels (main quantum number), n = 1 and n = 2, around the nucleus.
Explanation:
The period number of an element in the periodic table is always equal to the number of main energy levels that the atoms have.
Li (lithium), C (carbon), and F (fluor) form part of the period 2 of the periodic table.
The complete list of elements of the period 2 of the periodic table is Li, Be, B, C, N, O, F, and Ne.
The periods are numbered from 1 through 7.
The elements of period 1 (H and He) have one main energy level, the elements in period 2 have two main energy levels, the elements in period 3 (Na, Mg, Al, Si, P, O, Cl, and Ne) have three main energy levels. So, as you can infere, the period number always equals the number of main energy levels of the atoms of the element.
