yes are the best answer for the question

Answer 2

Answer:

(1)

Iodine provides an excellent example of sublimation. ... When solid iodine crystals are heated (in a beaker with hot sand) the iodine will change from a solid directly to a gas without passing through a liquid phase. This is called sublimation....

(2)Yes, a pure substance is always homogeneous. Why, because a homogeneous mixture is one that is pure appears to have no chunks. As oppose to a heterogeneous mixture which is chunky and isn't so smooth. Homogeneous Mixture Examples: vinegar, sea water, soft drinks (most), glass, and what is none as solutions....
