Question

1. what is the reaction between an acid and a base that produces a salt and water called?

a. an endpoint reaction
b. a titration reaction
c. a neutralization reaction
d. a synthesis reaction

1. when one element replaces another element in a compound, what is this type of reaction called?

a. decomposition
b. synthesis
c. single - replacement
d. double - replacement

1. which models shows a decomposition reaction?

Explanation:

• Question 5:
• An endpoint reaction is related to the point in a titration where a color change occurs. Titration is a method to determine the concentration of a solution. A synthesis reaction is when two or more substances combine to form a new compound. A neutralization reaction is specifically the reaction between an acid and a base to produce a salt and water.
• Question 6:
• Decomposition is when a compound breaks down into simpler substances. Synthesis is the combination of substances. Single - replacement is when one element replaces another in a compound. Double - replacement is when the ions of two compounds exchange places.
• Question 7:
• A decomposition reaction is when a single compound breaks down into two or more simpler substances. In option D, one compound breaks into two simpler substances. Option A is a double - replacement - like reaction (exchange of parts between two compounds). Option B is a synthesis reaction (combination of two elements or simple substances into a compound). Option C is a single - replacement reaction (one element replaces another in a compound).

Answer:

• 5. C. A neutralization reaction
• 6. C. single - replacement
• 7. D
