Question

Some liquid medications have "shake well before use" as part of their instructions. What type of mixture are they and why would you need to shake it?

Answer 1

Answer:

they are non homogeneous mixtures

Explanation:

means their components aren't of same size or have different charges which don't let them distribute evenly in the medium ,after some time the heavy or large particles settle down ,that's why it's advised to shake them to make them homogeneous to get all components equally
