What is a substance?
300
A change into a different substance.
What is a chemical property?
300
Mixture that is evenly mixed, so you cannot see the different parts.
What is homogeneous mixture?
300
Change in matter producing new substances (and always involving a change of energy).
What is a chemical change?
300
A reaction in which energy is released, such as freezing water.
What is exothermic?
