Question

write the balanced equation for the following reaction and identify the type of reaction potassium+chlorine ( g) potassium​

Answer 1

Answer:

(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 reaction

(d) 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
