Question

types of chemical reactions quiz chemistry b beach el(a-f) semester 2 3761 / module 7 chemical reactions 2. what type of reaction occurs when lithium metal is combined with fluorine gas to form lithium fluoride? synthesis combustion decomposition replacement

Explanation:

Step1: Recall reaction types

Synthesis reaction: \( A + B
ightarrow AB \) (two or more substances combine to form a single product).

Step2: Analyze the reaction

Lithium (Li) + Fluorine (\( F_2 \)) → Lithium fluoride (LiF). Two reactants (Li and \( F_2 \)) combine to form one product (LiF), matching synthesis.
Combustion needs oxygen and fuel (not here). Decomposition is \( AB
ightarrow A + B \) (opposite). Replacement involves element replacing in a compound (not here).

Answer:

synthesis
