What is the difference between a physical and a chemical change?
Physical Change- A change in the size, shape, form, or state of matter that does not change the matters identity. A new substance is not formed
Chemical Change- A change in matter in which the substance with different chemical and physical properties. Permanent.
What is the difference between a heterogeneous and homogeneous mixture
A homogeneous mixture is a mixture which two or more substances are evenly mixed, but not bonded together.
