Question

Which reaction below represents a balanced, single replacement chemical reaction?

Answer 1

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 2

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, $Cd + H_{2}SO4 \rightarrow H_{2} + CdSO_{4}$ 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 $Cd + H_{2}SO4 \rightarrow H_{2} + CdSO_{4}$ represents a balanced, single replacement chemical reaction.
