Which reaction below represents a balanced, single replacement chemical reaction?
A) C2H5OH + 3O2 → 2CO2 + 3H2O
B) BaF2 + Li → LiF + Ba
C) Cd + H2SO4 → H2 + CdSO4
D) H2O → H2 + O2

The balanced chemcial equation is B. So to do single, we need to look at where would Li stand on the metals chart (For my class we have a chart to see which element is the highest on the metals chart) . So since Li is higher, F needs to go with Li, leaving Ba alone.

I hope this helps you!

Answer: Option (C) is the correct answer.

Explanation:

A single replacement reaction is defined as the reaction where an element upon reaction with a compound tends to displace another element in that compound.

For example, [tex]Cd + H_{2}SO4 \rightarrow H_{2} + CdSO_{4}[/tex] is a single replacement reaction.

And, when number of atoms on reactant side equal to the number of atoms on product side then it is known as a balanced chemical reaction.

Thus, we can conclude that [tex]Cd + H_{2}SO4 \rightarrow H_{2} + CdSO_{4}[/tex] represents a balanced, single replacement chemical reaction.
