Answer:
We are to write the orbital notation and electronic configuration of sulfur and iron.
The orbital notation shows the filling of electrons into orbitals or sublevels.
Electron configuration shows the distribution of electrons into shells;
Number of electrons Electron configuration Orbital notation
S 16 2 8 6 1s² 2s² 2p⁶ 3s² 3p⁴
Fe 26 2, 8, 14 2 1s² 2s² 2p⁶ 3s² 3p⁶3d⁶4s²
Explanation:
Answer:
The fire may grow bigger, depending on the gas.
Explanation:
If you expose more air to a small flame then it could grow larger because air keeps fire alive.
I would say it is a function of all of the choices. if not then the answer is the circulatory system
Answer:
A.) 34.866 x 10¯23 g/atom
B.) 2.64 x 10^22 atoms in 1 cm3
C.) 1 atoms per unit cell
Explanation:
A) Calculate the average mass of one atom of polonium:
210g mol¯1 ÷ 6.022 x 1023 atoms mol¯1 = 34.866 x 10¯23 g/atom
B) Determine atoms in 1 cm3:
9.19g / 34.866x 10¯23 g/atom = 2.64 x 10^22 atoms in 1 cm3
Determine volume of the unit cell:
(3.37 x 10¯8 cm)3 = 3.827 x 10¯23 cm3
Determine number of unit cells in 1 cm3:
1 cm3 / 3.827 x 10¯23 cm3 = 2.61 x 1022 unit cells
C) Determine atoms per unit cell:
2.64 x 1022 atoms / 2.61 x 1022 unit cells = 1 atoms per unit cell
