Is lucky charms cereal a homogeneous or heterogeneous ? can u explain it to because i don’t understand

answer:

lucky charms cereal is a heterogeneous mixture

explanation:

a heterogeneous mixture is made of two (or more) substances that are mixed or combined together, but not dissolved together. it is not the same consistency throughout and can be separated into its original parts.

lucky charms has both average sugar cereal and marshmallows. if you add milk to this already existing heterogeneous mixture, it remains heterogeneous since milk is a separate substance that doesn't dissolve into cereal.

i 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
