Question

use the equation to answer the question.
a + b → ab
which type of reaction is modeled by the equation?
(1 point)
○ double replacement
○ single replacement
○ synthesis
○ decomposition

Explanation:

To determine the reaction type, we analyze the equation \( A + B
ightarrow AB \). A synthesis reaction combines two or more reactants into a single product. Double replacement involves two compounds exchanging ions, single replacement has one element replacing another in a compound, and decomposition breaks a compound into simpler substances. Here, \( A \) and \( B \) combine to form \( AB \), matching synthesis.

Answer:

C. synthesis
