In a chemical process, atoms that make up a substance are regrouped into different (a) to form new substances with different properties
A (a) increase or decrease and the production of light are both signs that a chemical reaction may have occurred
A (a) is a solid substance that forms and separates from a solution and may indicate that a chemical reaction has occurred
An unexpected change in (a) is a sign that a chemical reaction may have occurred.
Substances giving off a smell, or (a) , while being combined is also an indicator of a chemical reaction

Molecules are speeding up
Molecules are slowing down
What is the Law of Conservation of Mass?
Atoms can be destroyed if there are too many
Mass can be created if there is enough energy
Mass cannot be created nor destroyed
Mass can always be created or destroyed
What happens to the number of atoms?
Atoms can sometimes increase
