Across
- 4. what goes on the right side of a chemical equation (this is what the chemical reaction creates)
- 7. a way for us to write out a chemical reaction and make sure that the number of atoms is conserved (hint: it's the longest word here!)
- 9. a combination of 2 or more atoms (either the same atoms or can be different atoms)
Down
- 1. this is what we use in chemical equations that's like the equal sign in a math problem
- 2. substance that is made entirely from one type of atom (these are found on the periodic table)
- 3. what goes on the left side of a chemical equation (you add them up together)
- 5. Type of reaction where the substance is molecularly different afterward (ex. baking a cake)
- 6. Type of reaction where the substance is still the same after the reaction (ex. phase changes)
- 8. smallest unit of matter, can usually be identified by seeing single elements not combined
