Explanation

Magnesium Sulphate is also known as Epsom salt.

It is an inorganic salt.

Its formula is MgSO4(H2O)x.

The formula of Epsom salt is MgSO₄·7H₂O (heptahydrate sulphate mineral epsomite).

Magnesium Sulphate is used in the field of agriculture.

Epsom Salt is used as a component of bath salts, beauty products, to improve crops and removal of splinters.

Explanation

It neutralizes stomach acid, making it useful as an antacid.

It produces carbon dioxide when heated or mixed with acid, which helps in baking and fire extinguishers.

Explanation

When cyclohexane is oxidized with nitric acid (HNO₃), it typically yields adipic acid.

Adipic acid is a dicarboxylic acid with the formula C₆H₁₀O₄, and it is commonly used in the production of nylon. 

Explanation

Ferromagnetic materials are those that can be magnetized and retain their magnetization even after the external magnetic field is removed.

These materials have a high magnetic permeability and strong interactions between magnetic moments, which align in the same direction.

Explanation

This is done through an electrophilic attack on the aromatic ring with the help of a carbonation.

The Friedel-Crafts alkylation reaction is a method of generating alkylbenzenes by using alkyl halides as reactants.

The Friedel-Crafts alkylation reaction of benzene is illustrated below.

Explanation

Carbon dioxide (CO₂) is the gas commonly used in carbonated beverages.

It dissolves in the liquid under pressure, creating the fizzy bubbles that are characteristic of drinks like:

• soda
• sparkling water
• beer
  

Explanation

 The energy required to break down a nucleus into its constituent protons and neutrons is called nuclear binding energy. 

Explanation

Formic acid is present in the sting of ants.

It causes a sharp, burning sensation and irritation when injected into the skin during an ant sting.

Explanation

The incorrect statement is "sigma bond is weaker than a pi bond" because a sigma bond is stronger than a pi bond.

Sigma bond: Formed by direct head-on overlap of orbitals, resulting in a strong bond. 

Pi bond: Formed by sideways overlap of p orbitals, resulting in a weaker bond compared to a sigma bond.
