What is the best definition of a chemical change?
A change in the state of matter in which the form changes but the properties stay the same.
A change in the state of matter in which the material changes into an entirely different material with properties that are different from the original material.
A change in the state of matter in which the material is still the same just in a different form.
Which is not evidence that a chemical reaction has occured

In a chemical reaction, mass is conserved. This means that
The mass of the products stays the same during a chemical reaction
The mass of the products is always twice the mass of the reactants
The mass of the reactants stays the same during a chemical reaction
The type and number of atoms in the reactants equals the type and number of atoms in the products
The law of conservation of mass states
matter can not be created or destroyed
matter can be created and destroyed
matter can be changed and created
matter can be rearranged and destroyed
