The measurement was conducted in the sealed vial containing air and ethanol at two different pressures and temperatures: 890.27 mmhg at 27 ∘ c and 908.53 mmhg at 40 ∘ c. from earlier measurements one found that the pressure of air at 27 ∘ c is 760.05 mmhg. what is the vapor pressure?

Which is a difference between molecular compounds and ionic compounds? select the correct answer below: question 5 options: molecular compounds typically form between a metal and a nonmetal, while ionic compounds typically form between nonmetals. molecular compounds result from the transfer of electrons between atoms to form ions, while ionic compounds result from the sharing of electrons between neutral atoms. molecular compounds are formed of discrete, neutral molecules, while ionic compounds are formed of large repeating arrays of opposite charges. molecular compounds have high melting points and high boiling points, while ionic
