Thermal decomposition of limestone produces: MCQ with Answer and Explanation

Explanation:
Neutralization is a chemical reaction in which an acid and a base react quantitatively with each other to form a salt and water. For example, HCl + NaOH → NaCl + H₂O. It is generally an exothermic process, and the resulting solution has a pH closer to 7.

Explanation:
Neutralization: Acid + Base → Salt + Water. Example: HCl + NaOH → NaCl + H₂O. It is a double displacement reaction. The pH of the resulting solution may be neutral, acidic, or basic depending on the strengths of the acid and base.

Explanation:
Bakelite, the first fully synthetic plastic, is a thermosetting phenol formaldehyde resin. It is formed by a condensation reaction between phenol and formaldehyde. Once molded and heated, it sets permanently and cannot be remelted. It is used for electrical switches, utensil handles, and jewelry.
