Across
- 7. chemical reactions in which the reactants absorb heat energy from the surroundings to form products.
- 8. condition in the course of a reversible chemical reaction in which no net change in the amounts of reactants and products occurs.
- 10. a number assigned to an element in chemical combination which represents the number of electrons lost
- 11. a substance that results from a chemical reaction
- 12. a reaction in which the conversion of reactants to products and the conversion of products to reactants occur simultaneously.
- 15. a chemical reaction where electrons are transferred between atoms, with one atom losing electrons (oxidized) and another atom gaining electrons (reduced)
Down
- 1. gains electrons and is reduced in a chemical reaction
- 2. a chemical reaction that involves the release of energy in the form of heat or light.
- 3. cause (a substance) to be deposited in solid form from a solution.
- 4. loses electrons and is oxidized in a chemical reaction
- 5. a chemical reaction where a substance gains electrons, resulting in a decrease in its oxidation state
- 6. a list of elements in decreasing order of their reactivity
- 9. expresses the relationship between products and reactants of a reaction at equilibrium with respect to a specific unit.
- 13. a substance that takes part in and undergoes change during a reaction.
- 14. a protein that acts as a biological catalyst
