- 3. reactant a reactant that is not completely used up in a chemical reaction
- 5. rate the change in concentration of reactant or products in a chemical reaction over time
- 8. equilibrium the state at which the rate of the forward reaction equals the rate of the reverse reaction for a chemical reaction
- 10. reaction an endothermic reaction that occurs when an ionic compound dissolves in water to make an ionic solution
- 13. describes a solution with a concentration greater than the maximum solubility
- 16. to separate and disperse a solid into individual particles in the presence of a solvent
- 18. a solution of two or more solids
- 20. energy energy needed to break chemical bonds in the reactants to start a reaction
Down
- 1. fission a nuclear reaction in which the nuclei of heavier atoms are split to make lighter atoms
- 2. effect the scattering of light by the particles in a colloid
- 4. describes a chemical reaction that releases more energy than it uses
- 6. the reaction of an acid and a base to produce a salt and water
- 7. reactant a reactant that is used up first in a chemical reaction
- 9. describes a solution that has as much solute as the solvent can dissolve under the conditions
- 11. a substance that produces hydroxide ions (OH-) when dissolved in water
- 12. describes a chemical reaction that uses more energy than it releases
- 14. scale it goes form 1 to 14 with 1 being very acidic and 14 being very basic
- 15. a molecule added to a chemical reaction that increases the reaction rate without getting used up in the process
- 17. molecule a molecule that does not have distinctly-charged poles
- 19. percent the mass of the solute divided by the total mass of the solution multiplied by 100
