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) b. p2o5(s) --> p2(s) + o2(g) c. p(s) + o(g) --> p5o2(g) d. p(s) + o2(g) --> po2(g)

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 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.

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.

Yes, this is the correct combination equation.

No, this is a decomposition equation. Also, elemental phosphorus is not diatomic.

No, since P₅O₂ is not diphosphorus pentoxide and elemental oxygen is diatomic.

No, since PO₂ 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)

the ideal gas law equation is as follows

pv = nrt

where p - pressure

v - volume

n - number of moles

r - universal gas constant

t - temperature

so if the pressure, volume and temperature are already known

we are left with n and r

since r is the universal gas constant that has a known fixed value then r too is known

so we are left with 'n'

once we know temperature volume and pressure

we can find the number of moles of gas present using the ideal gas law equation
