Question

what type of reaction is bf₃ + li₂so₃ → b₂(so₃)₃ + lif? synthesis single replacement combustion decomposition none of these

Explanation:

• Synthesis reaction: Two or more reactants combine to form a single product. Here, we have two reactants ($BF_3$ and $Li_2SO_3$) and two products ($B_2(SO_3)_3$ and $LiF$), so it is not a synthesis reaction.
• Single - replacement reaction: One element replaces another element in a compound. The general form is $A + BC

ightarrow AC + B$. In our reaction $BF_3+Li_2SO_3
ightarrow B_2(SO_3)_3 + LiF$, it is not in the form of a single - replacement reaction.

• Combustion reaction: A substance reacts with oxygen to produce carbon dioxide and water (for organic compounds) or other oxides. There is no oxygen involved in the given reaction, so it is not a combustion reaction.
• Decomposition reaction: A single reactant breaks down into two or more products. Here we have two reactants, so it is not a decomposition reaction.

Answer:

None of these
