Which of the following cannot be considerded a single phase? (1 point)

answer:

a pure solid and a pure liquid are definitely a single phase because they are so united, or homogeneous. this leads to a homogeneous mixture also being a single phase. the option that cannot be considered a single phase is d. a heterogeneous mixture.

explanation:

hope this : )

in the given question, the partial pressure is calculated by using the ideal gas equation, that is, pv = nrt

here, p is pressure, v is volume = 25 l, n is number of moles = 0.0104 moles, r is gas constant = -0.0821 l.atm / mol.k

t is temperature = 273 k

p = nrt / v

p = (0.0104 mol × 0.0821 l.atm / mol.k × 273 k) / 25 l

= 0.0093 atm
