Question

10 which type of reaction is the equation: a + b → ab
a single replacement
b synthesis
c decomposition
d double replacement

Explanation:

• In a synthesis reaction, two or more reactants combine to form a single product. Here, \(A + B\) (two reactants) combine to form \(AB\) (a single product).
• In a single - replacement reaction, one element replaces another in a compound (\(A+BC

ightarrow AC + B\)).

• In a decomposition reaction, a single compound breaks down into two or more simpler substances (\(AB

ightarrow A + B\)).

• In a double - replacement reaction, the positive and negative ions of two ionic compounds exchange places (\(AB+CD

ightarrow AD + CB\)).

Answer:

B. Synthesis
