I hope this helps you alot and to my understanding:)
Answer:
Partia pressure N₂ → 0.975 atm
Explanation:
Let's analyse the moles fractions:
N₂ → 0.25
O₂ → 0.65
He → 0.1
Partial pressure / Total pressure = Mole fraction
Partial pressure N₂ / 3.9 atm = Mole fraction N₂
Partial pressure N₂ / 3.9 atm = 0.25
Partial pressure N₂ = 3.9 atm . 0.25 → 0.975 atm
Compounds that has two elements on the formula can be bonded by ionic or covalent bond. If the compound is a metal and a non-metal then it will be ionic bonding. However, when it involves two non-metals, then it will have covalent bonding.
