Unit 3
Across
- 5. | A solution that temporarily contains more than the maximum amount of dissolved solute (more than a saturated solution) at a specific temperature.
- 9. | A process or reaction that releases energy, usually in the form of heat, to the surroundings.
- 11. a homogeneous mixture of two or more substances
- 13. Reaction | A process that involves the rearrangement of the molecular or ionic structure of a substance, as opposed to a change in physical form or a nuclear reaction
- 15. Displacement | A type of chemical reaction where the ions of two compounds exchange places in an aqueous solution to form two new compounds.
- 17. | A solid that is formed in a solution during a chemical reaction. The formation of a precipitate is often indicated by the abbreviation $ (s) $ in a chemical equation.
- 19. Equation | A symbolic representation of a chemical reaction using chemical formulas to represent the reactants and products. The arrow (→) indicates the direction of the reaction.
- 20. Displacement | A type of chemical reaction where one element replaces another element in a compound.
- 21. | A number written slightly below and to the right of a chemical symbol in a formula, indicating the number of atoms of that element in the molecule.
Down
- 1. | A solution that contains the maximum amount of dissolved solute possible under the given conditionsUnsaturated | A solution that contains less than the maximum amount of dissolved solute.
- 2. the substance that is dissolved in another substance (the solvent) to form a solution. It's usually the component present in the smaller amount.
- 3. | A substance that produces hydroxide ions (OH−) when dissolved in water
- 4. | A solution that contains less than the maximum amount of dissolved solute.
- 6. | A type of chemical reaction where a single compound breaks down into two or more simpler substances.
- 7. | A process or reaction that absorbs energy, usually in the form of heat, from the surroundings.
- 8. | A solution containing a relatively large amount of solute per unit volume of solvent.
- 10. | A number placed in front of a chemical formula in a chemical equation to balance the reaction, indicating the relative number of molecules or moles of the substance.
- 12. | A number or symbol written slightly above and to the right of a chemical symbol, usually indicating the charge (oxidation state) of an ion
- 14. | The process where an ionic compound or a molecule separates or breaks apart into smaller ions, atoms, or molecules, usually when dissolved in a solvent like water.
- 16. | A type of chemical reaction where two or more simple substances combine to form a more complex substance.
- 18. | A substance that produces hydrogen ions (H+) when dissolved in water
