Question

which is produced in a synthesis reaction?
○ a single element
○ a single compound
○ a single ion
○ a single atom

Explanation:

A synthesis reaction is a type of chemical reaction where two or more reactants combine to form a single product. The general form is \( A + B
ightarrow AB \), where \( AB \) is a compound. Elements combine to form compounds in synthesis reactions, so the product is a single compound. A single element, ion, or atom is not typically the product of a synthesis reaction (as synthesis involves combining substances to form a more complex substance, usually a compound).

Answer:

a single compound
