- 6. The substance that dissolves the solute to form a solution, typically present in a greater amount.
- 8. A group of atoms bonded together, representing the smallest fundamental unit of a chemical compound.
- 10. Energy The minimum energy required to initiate a chemical reaction.
- 12. Reaction A chemical reaction that releases heat to its surroundings, resulting in an increase in temperature of the reaction mixture.
- 14. A measure of concentration, defined as the number of moles of solute per liter of solution.
- 16. A measure of the acidity or basicity of an aqueous solution, ranging from 0 (acidic) to 14 (basic), with 7 being neutral.
- 18. Reaction A chemical reaction that absorbs heat from its surroundings, resulting in a decrease in temperature of the reaction mixture.
- 20. The tendency of an atom to attract electrons in a chemical bond.
- 23. A substance that accepts protons (H⁺ ions) in a chemical reaction and typically has a bitter taste and slippery feel.
- 25. The study of the relations between heat, work, temperature, and energy in chemical processes.
- 27. A substance that increases the rate of a chemical reaction without being consumed or permanently altered by the reaction.
- 28. Reaction A process in which one or more substances (reactants) are transformed into one or more different substances (products).
- 29. A state in a chemical reaction where the rate of the forward reaction equals the rate of the reverse reaction, leading to constant concentrations of reactants and products.
Down
