Answer: Option (A) is correct.
Explanation:
In diphosphorus pentoxide there will be two phosphorous atoms and 5 oxygen atoms according to its name.
Therefore, the formula for diphosphorus pentoxide will be [tex]P_{2}O_{5}[/tex] and it is a solid.
Thus, the correct skeleton equation for the reaction that takes place when solid phosphorus combines with oxygen gas to form diphosphorus pentoxide will be as follows.
         [tex]P(s)+ O_{2}(g) \rightarrow P_{2}O_{5}(s)[/tex]
The correct skeleton equation for the reaction that takes place when solid phosphorus combines with oxygen gas to form diphosphorus pentoxide is:
A. P(s) + O₂(g) ⇒ P₂O₅(s)
Let's consider which of the following is the correct skeleton equation for the reaction that takes place when solid phosphorus combines with oxygen gas to form diphosphorus pentoxide.
A. P(s) + O₂(g) ⇒ P₂O₅(s)
Yes, this is the correct combination equation.
B. P₂O₅(s) ⇒ P₂(s) + O₂(g)
No, this is a decomposition equation. Also, elemental phosphorus is not diatomic.
C. P(s) + O(g) ⇒ P₅O₂(g)
No, since Pâ‚…Oâ‚‚ is not diphosphorus pentoxide and elemental oxygen is diatomic.
D. P(s) + O₂(g) ⇒ PO₂(g)
No, since POâ‚‚ is not diphosphorus pentoxide.
The correct skeleton equation for the reaction that takes place when solid phosphorus combines with oxygen gas to form diphosphorus pentoxide is:
A. P(s) + O₂(g) ⇒ P₂O₅(s)
