Amixture of nitrogen gas and oxygen gas has a total pressure of l.13 atm. if the partial pressure of oxygen is 0.43 atm, what is the partial pressure of nitrogen?

a) 1.56 atm
b) 1.13 atm
c) 0.70 atm
d) 0.38 atm

0.70 atm - Option C

Explanation:

Let's apply the mole fraction concept to solve this:

Partial pressure of a gas / Total pressure = Mole fraction of a gas.

In a mixture, sum of mole fraction from each gas = 1

Partial pressure of O₂ / Total pressure = Mole fraction of O₂

0.43 atm / 1.13 atm = 0.380

1 - 0.380 = 0.62 → Mole fraction N₂

Mole fraction N₂ = Partial pressure N₂ / Total pressure

0.62 = Partial Pressure N₂ / 1.13 atm

0.62 . 1.13 = 0.70 atm → Partial Pressure N₂

answer: option (b) is the correct answer.

explanation:

a covalent bond is formed by sharing of electrons. whereas polarity arises due to difference in electronegativity of two atoms.

therefore, more is the electronegativity of an atom which combines with the titanium, more readily it will induce a partial positive and negative charge.

thus, out of the given options fluorine is most electronegative and has an incomplete octet. therefore, it will readily combine with titanium to share the electrons and complete its octet.  

i'm assuming that the correct answer is indeed the first one/ "a"..
