Answer:

Explanation:

(a) Potassium bromide(aq) + Barium iodide(aq) → Potassium iodide(aq) + Barium bromide(s)

2KBr  

(aq)

​  

+BaI  

2

​  

 

(aq)

​  

→2KI  

(aq)

​  

+BaBr  

2

​  

 

(s)

​  

 

In this reaction, both the reactants exchanges ions to for two new products, hence, it is a double displacement reaction

(b) zinc carbonate(s) → Zinc oxide(s) + Carbon dioxide(g)

ZnCO  

3

​  

 

(s)

​  

→ZnO  

(s)

​  

+CO  

2

​  

 

(g)

​  

 

In this reaction, a single substance yields two different product. hence, it is a decomposition reaction

(c) Hydrogen(g) + Chlorine(g) → Hydrogen chloride(g)

H  

2

​  

 

(g)

​  

+Cl  

2

​  

 

(g)

​  

→2HCl  

(g)

​  

 

In this reaction, two different reactants react with each other to form a single product. Hence, it is called a combination reactiond) Magnesium(s) + Hydrochloric acid(aq) → Magnesium chloride(aq) + Hydrogen(g)

Mg  

(s)

​  

+2HCl  

(aq)

​  

→MgCl  

2

​  

 

(aq)

​  

+H  

2

​  

 

(g)

​  

 

In this reaction, more reactive Mg is replacing less reactive H. Hence, it is displacement reaction
