Name one chemical change and one physical change.
Many different answers one example of each:
In a physical change, the material involved in the change is structurally the same before and after the change --> Ice Melting
Chemical Change:A chemical change is a change of materials into another, new materials with different properties and one or more than one new substances are formed.--> Iron nail rusting

What is the difference between a homogenous and heterogenous mixture.
homogeneous means that the properties of a system are the uniform throughout the entire system, composition of mixture is uniform throughout; heterogeneous means that the properties change within the system so the composition changes throughout
