Answer 1

$\huge\bf{\pink{\underline{\underline{\mathcal{AnSwer࿐}}}}}$

A.) Balanced chemical equations of the following:-

• Magnesium reacts with Hot water

$\implies$ $\sf Mg$ + $\sf 2H_{2}O$ $\longrightarrow$ $\sf Mg(OH)_{2}$ + $\sf H_{2}$

• Zinc reacts with Sulphuric acid

$\implies$ $\sf Zn$ + $\sf H_{2}SO_{4}$ $\longrightarrow$ $\sf ZnSO_{4}$ + $\sf H_{2}$

• Aluminium reacts with Hydrochloric acid

$\implies$ $\sf 2Al$ + $\sf 6HCl$ $\longrightarrow$ $\sf 2AlCl_{3}$ + $\sf 3H_{2}$

B.) Observation of the reaction :-

$\implies$ $\sf X$ + $\sf YCl$ $\longrightarrow$ $\sf XCl$ + $\sf Y$

• this is a single displacement reaction, because here, the more reactive element x has displaced less reactive element y from its chloride salt of YCl.

A.) Balanced chemical equations of the following:-

Magnesium reacts with Hot water

⟹\implies⟹ Mg\sf MgMg + 2H2O\sf 2H_{2}O2H

2

O ⟶\longrightarrow⟶ Mg(OH)2\sf Mg(OH)_{2}Mg(OH)

2

+ H2\sf H_{2}H

2

Zinc reacts with Sulphuric acid

⟹\implies⟹ Zn\sf ZnZn + H2SO4\sf H_{2}SO_{4}H

2

SO

Aluminium reacts with Hydrochloric acid

⟹\implies⟹ 2Al\sf 2Al2Al + 6HCl\sf 6HCl6HCl ⟶\longrightarrow⟶ 2AlCl3\sf 2AlCl_{3}2AlCl

3

+ 3H2\sf 3H_{2}3H

B.) Observation of the reaction :-

⟹\implies⟹ X\sf XX + YCl\sf YClYCl ⟶\longrightarrow⟶ XCl\sf XClXCl + Y\sf YY

this is a single displacement reaction, because here, the more reactive element x has displaced less reactive element y from its chloride salt
