Chemical Reactions

2. Energy The minimum amount of energy required for a chemical reaction to occur.
4. A substance that speeds up a chemical reaction without being consumed in the process.
7. A solid that forms and separates from a solution during a chemical reaction.
9. The substances that are formed as a result of a chemical reaction.
12. A homogeneous mixture composed of a solute dissolved in a solvent.
13. A biological catalyst that speeds up chemical reactions in living organisms.
14. A reaction that releases heat, causing the temperature of the surroundings to increase.
16. A reaction where a single compound breaks down into two or more simpler substances.
18. of Reaction The speed at which reactants are converted into products in a chemical reaction.
20. The substance that is dissolved in a solvent to form a solution.
21. The calculation of the quantities of reactants and products in a chemical reaction.
25. The substance in a solution that dissolves the solute.
26. The process of losing electrons in a chemical reaction.
28. A chemical reaction in which a substance reacts with oxygen, often producing heat and light.
29. Chatelier’s Principle States that if a system at equilibrium is disturbed, the system will adjust to counteract the disturbance and restore equilibrium.

1. A reaction that absorbs heat, causing the temperature of the surroundings to decrease.
3. A chemical reaction in which two or more simple substances combine to form a more complex substance.
5. The process of gaining electrons in a chemical reaction.
6. Bond A chemical bond formed through the transfer of electrons from one atom to another, creating charged ions.
8. The amount of a substance in a given volume of solution.
10. A substance that takes part in and undergoes change during a chemical reaction.
11. Reaction A reaction between an acid and a base that usually produces water and a salt.
15. A state in which the forward and reverse reactions occur at the same rate, maintaining a constant concentration of reactants and products.
17. Bond A chemical bond formed when two atoms share electrons.
19. A reaction that involves the transfer of electrons between two substances.
22. Equation A symbolic representation of a chemical reaction using element symbols and formulas to show reactants and products.
23. Complex A temporary, unstable arrangement of atoms that forms at the peak of the activation energy barrier during a reaction.
24. Replacement A reaction where the positive ions of two compounds exchange places to form two new compounds.
27. Replacement A chemical reaction in which one element replaces another in a compound.
29. of Conservation of Mass States that mass is neither created nor destroyed in a chemical reaction.
