30 pts! balancing equations. 2. for part 2: single-displacement reactions: for each of the four single-displacement reactions, describe what happened in each well. if a chemical reaction occurred, write a balanced equation for it. then using the a, b symbols, write a general equation for a single-displacement reaction. a+bc=ac+b here are the chemical formulas of the reactants for each reaction: • zinc – zn copper sulfate – cuso4 zn+cuso4-> cu+znso4 • aluminum – al copper sulfate – cuso4 no reaction • zinc – zn silver nitrate – ag(no3) • copper – cu silver nitrate – ag(no3)

Answer :

Single-displacement reaction : It is a type of reaction in which a more reactive metal displace the less reactive metal from the solution.

General equation for single-displacement reaction is,

In this reaction, A displaces B because A is more reactive than B.

These reactions answered on the basis of reactivity series. The reactivity series image is shown below.

The balanced reaction is,

When zinc react with copper sulfate then zinc displaces the copper from copper sulfate because zinc is more reactive metal than the copper.

The balanced reaction is,

When aluminium react with copper sulfate then aluminium displaces the copper from copper sulfate because aluminium is more reactive metal than the copper.

The balanced reaction is,

When zinc react with silver nitrate then zinc displaces the silver from silver nitrate because zinc is more reactive metal than the silver.

The balanced reaction is,

When copper react with silver nitrate then copper displaces the silver from silver nitrate because copper is more reactive metal than the silver.

the answers are
