a chemical reaction has the equation 2nacl (aq) + f₂ (g) → 2naf (s) + cl₂ (g). what type of reaction occurs between nacl and f₂?
a) double displacement
b) decomposition
c) synthesis
d) single displacement

Explanation:

1. Analyze each reaction type:

• Double displacement: Involves two compounds exchanging ions (e.g., \(AB + CD

ightarrow AD + CB\)). Here, \(F_2\) is an element, not a compound, so not double displacement.

• Decomposition: Breaks a compound into simpler substances (e.g., \(AB

ightarrow A + B\)). The reaction here has two reactants, so not decomposition.

• Synthesis: Combines substances into a single compound (e.g., \(A + B

ightarrow AB\)). The products are two substances, so not synthesis.

• Single displacement: An element replaces another in a compound (e.g., \(A + BC

ightarrow AC + B\)). In \(2NaCl(aq)+F_2(g)
ightarrow 2NaF(s)+Cl_2(g)\), \(F_2\) (element) replaces \(Cl\) in \(NaCl\) to form \(NaF\) and \(Cl_2\) (element), matching single displacement.

Answer:

D) Single displacement
