Answer:
Pressure of O₂ = 0.93 atm
Pressure of krypton = 3.32 atm
Explanation:
This problem can be solved by using Dalton's Law of Partial Pressures, which states that the partial pressure of a component of a gaseous mixture depends on the mole ratio of said component and the total pressure of the gaseous mixture.
Pₐ = Xₐ * Ptotal
P
ₐ - the partial pressure of component a
χ
ₐ - its mole fraction in the mixture
P
total - the total pressure of the mixture
The moles of the two gases are:
moles of O₂ = 11.2/32 = 0.35 moles
moles of krypton = 104.75/83.8 = 1.25 moles
Total moles = 1.25 + 0.35 = 1.6 moles
Xₐ = number of moles of a /total moles in mixture
Pressure of O₂ = 0.35/1.6 *4.25 = 0.93 moles
Pressure of krypton = 1.25/1.6 *4.25 = 3.32 moles

Answer:
you know just in order to bring that nostalgia into chemists minds
Explanation:
Answer:
Sodium chloride is an ionic compound which makes it stronger and have a higher melting and boiling point. Candle wax is a covalent compound so it has a low melting point.
