Across
- 3. reaction there is a net absorption of energy.
- 6. AB + C → AC + B
- 9. AB + CD → AD + CB
- 10. No atoms are gained or lost during any reaction.
Down
- 1. a+ B → AB
- 2. AB + oxygen → oxides of A & B
- 4. To reflect this fact, the chemical equation must be.
- 5. AB→ A + B
- 7. reaction there is a net release of energy.
- 8. Bond Energy is also known as
