Question

Write and balance the following single
replacement reaction.
c) Ag + CoBr₂

Answer 1

The balanced single replacement reaction for the given chemical equation "Ag + CoBr₂" is:

2Ag + CoBr₂ → 2AgBr + Co

In this reaction, silver (Ag) replaces cobalt (Co) in the compound CoBr₂ (cobalt(II) bromide) to form silver bromide (AgBr) and solid cobalt (Co). The reaction is balanced because the number of atoms of each element is equal on both the reactant and product sides of the equation.

Note that the coefficients are 2 in front of Ag and AgBr, indicating that two molecules of Ag and two molecules of AgBr are required to balance the reaction.
