<p> IPC – Chapter 24 Test Review</p><p>1. How do you know that you have a balanced equation?</p><p>2. Label the different parts of a chemical equation. (Use Products, Reactants, and the symbol )</p><p>3. What type of reaction occurs when you mix two chemicals and heat is produced?</p><p>4. What is the symbol that means dissolved in water?</p><p>5. If your reaction is taking too long, what can you add to help speed up the process?</p><p>6. Which equation is balanced?</p><p>A) AgNO3 + NaCl  AgCl + NaNO3 B) AgNO3 + 2NaCl  AgCl + 3NaNO3</p><p>Why did you pick that answer?</p><p>7. Draw an example (equation) of a A) Decomposition Reaction:</p><p>B) Synthesis Reaction:</p><p>C) Double Displacement:</p><p>D) Single Displacement:</p><p>8. Write in words what happens in a decomposition reaction.</p><p>9. Compare and contrast the following two words: Catalyst & Inhibitor</p><p>10. Put a square around the coefficients, and circle the subscripts.</p><p>AgNO3 + NaCl  4AgCl + 2NaNO3</p><p>11. What does the word “precede” mean?</p><p>12. Compare and contrast Endothermic and Exothermic reactions. (hint: which one gets hot and which one gets cold) 13. Explain the Law of Conservation of Mass.</p><p>14. If you have 5 carbon atoms in your reactant, how many carbon atoms will you have in your product? Which law explains this?</p><p>15. If your product is 2H2 + O2, what was your reactant? </p><p>What type of reaction is that?</p><p>16. What is the energy source for photosynthesis?</p><p>17. This is how you will see your balancing equations.</p><p>_____ Al + ______O2 ______Al2O3</p><p> a. 2,3,1 b. 2,3,2 c. 3,3,2 d. 4,3,2</p><p>18. You combine two reactants and find the sum total of the mass to be 200 grams. What would be the sum total of the resulting products be? </p><p>Which law tells us how to do this problem?</p><p>19. Why would you put an inhibitor for mold growth in food products?</p><p>20. 2HCl  2H + Cl2 (How many chlorine atoms do you have on the product side?)</p><p>21. What type of reaction is the following?</p><p>A + B  C + Heat</p><p>22. What is a sure sign detail that you have had a double displacement reaction?</p>
