IPC Chapter 24 Test Review

IPC – Chapter 24 Test Review

1. How do you know that you have a balanced equation?

2. Label the different parts of a chemical equation. (Use Products, Reactants, and the symbol )

3. What type of reaction occurs when you mix two chemicals and heat is produced?

4. What is the symbol that means dissolved in water?

5. If your reaction is taking too long, what can you add to help speed up the process?

6. Which equation is balanced?

A) AgNO3 + NaCl  AgCl + NaNO3 B) AgNO3 + 2NaCl  AgCl + 3NaNO3

Why did you pick that answer?

7. Draw an example (equation) of a A) Decomposition Reaction:

B) Synthesis Reaction:

C) Double Displacement:

D) Single Displacement:

8. Write in words what happens in a decomposition reaction.

9. Compare and contrast the following two words: Catalyst & Inhibitor

10. Put a square around the coefficients, and circle the subscripts.

AgNO3 + NaCl  4AgCl + 2NaNO3

11. What does the word “precede” mean?

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.

14. If you have 5 carbon atoms in your reactant, how many carbon atoms will you have in your product? Which law explains this?

15. If your product is 2H2 + O2, what was your reactant?

What type of reaction is that?

16. What is the energy source for photosynthesis?

17. This is how you will see your balancing equations.

_____ Al + ______O2 ______Al2O3

a. 2,3,1 b. 2,3,2 c. 3,3,2 d. 4,3,2

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?

Which law tells us how to do this problem?

19. Why would you put an inhibitor for mold growth in food products?

20. 2HCl  2H + Cl2 (How many chlorine atoms do you have on the product side?)

21. What type of reaction is the following?

A + B  C + Heat

22. What is a sure sign detail that you have had a double displacement reaction?
