Answer 1

1) Answer: Water

A homogeneous mixture has the same uniform appearance and composition throughout. Manyhomogeneous mixtures are commonly referred to as solutions.

Water itself is an example of a homogeneous mixture. It often contains dissolved minerals and gases, but these are dissolved throughout thewater

2) Answer:B(Dry ice Subliming)

sublimation is when a solid turns directly to a gas without the liquid stage. it is a physical change. because dry ice is CO₂. and when it turns into a gas its still CO₂ so no chemical change. however its not a solid anymore therefore physical change.
