d) Zn + H2SO4-----------------> ZnSO4 + H2
​

Answer 1

Explanation:

ANSWER:-

$Fe + ZnSO_{4} \longrightarrow FeSO_4 + Zn$

• This reaction is Feasable
• This is because it follows the laws of Displacement Reaction
• In this, one component displaces another component into he product formation.

$NaOH + HCl \longrightarrow NaCl + H_2O$

• This reaction is also applicable
• This is Double Displacement Reaction
• It is also Neutralisation Reaction
• Here Acid and Base gives out salt and water the Basic process of Neutralisation Reaction .
• Double Displacement also known as Methathesis Reaction or DD reaction

$Fe + FeSO_{4} \longrightarrow ZnSO_4 + Zn$

• This reaction is not feasable
• This is because the iron is in reactant side
• Zinc of product aside
• They both are different Elements
• Iron cannot react to form zinc in any case.

$Zn + H_2SO_{4} \longrightarrow ZnSO_4 + H_2$

• This is also applicable reaction
• In this, it follows Displacement Reaction
• Here Zinc is added to SO4 of Sulphuric Acid, so displaced

So, (c) part is the Correct Answer.

Displacement Reaction-

• Here, one component is displaced.
• It is also sometimes combined with Redox Reaction

Redox Reaction-

• A reaction where both Oxidation and Reduction Takes place
• Oxidation is gain of Oxygen and loss of Hydrogen
• Reduction is gain of Hydrogen and Loss of Oxygen
• Real life situations :- Causes Rancidity

Double Displacement Reaction-

• Also known as Methathesis Reaction
• Also known as DD reaction
• In this, both the components of Product as well as Reactant side, gets displaced.
• Associated Reacion :- Neutralisation Reaction.
