A covalent bond is formed.
Answer:
4 mol of Al₂O₃ are produced from 8 mole of Al
Explanation:
The reaction:
4 Al + 3O₂ → 2Al₂O₃
Ratio is 4:2
So, If we have 8 mol of Al, we will produce 4 mol of Al₂O₃
Answer:
2457.6
Explanation:
I calculated the answer and got it right.
The correct answer is A. It shows how electrons are distributed in the shells of an iron atom.
Explanation:
In the model described, the circles represent the orbitals or shells of the atom, while the dots represent the distribution of electrons (negatively charged sub-particles). Additionally, the description shows the general electronic configuration of this atom is 2, 8, 14, 2, which means in the first orbital there are two electrons, in the second there are eight electrons, in the third, there are fourteenth electrons and in the fifth orbital there are two electrons. This electronic configuration occurs in the atoms of iron. Also, this differs from Cobalt because in cobalt the third orbital has 15 electrons. Thus, the model "shows how electrons are distributed in the shells of an iron atom".
