<h3><u>Answer</u>;</h3>
B) Al2O3
<h3><u>Explanation;</u></h3>
Aluminium reacts with oxygen to form aluminium oxide.
The chemical reaction for the reaction between Aluminium and Oxygen is;
4Al+ 3O₂→ 2Al₂O₃
Therefore;
Compound X is Aluminium oxide (Al₂O₃)
Answer:
2.439 x 10E24 atoms
Explanation:
from
N=n x NA where
N- number of atoms
n-number of moles and NA is the avogadro's number
<span>1.49 x 10^22 atoms
First determine the molar mass of P2O5
Atomic mass of Phosphorus = 30.973762
Atomic mass of Oxygen = 15.999
Molar mass of P2O5 = 2 * 30.973762 + 5 * 15.999 = 141.9425
Now determine how many moles of P2O5 you have
0.500 / 141.9425 = 0.003523
Since there's a total of 7 atoms per molecule of P2O5, multiply the number of moles by 7 to get the number of moles of atoms you have.
7 * 0.003523 = 0.024661
Finally, multiply by avogadro's number (6.0221409 x 10^23) to get the total number of atoms.
0.024661 * 6.0221409 x 10^23 = 1.48512 x 10^22</span>
