Q1: Blasting of tri-nitro-toluene (TNT) is done by mixing it with ammonium

ANS:A - nitrate

Blasting of tri-nitro-toluene (TNT) is commonly done by mixing it with ammonium nitrate. TNT, or trinitrotoluene, is a powerful explosive compound commonly used in military and industrial applications. It is often mixed with other compounds to enhance its explosive properties or to create specific types of explosives. One common method is to mix TNT with ammonium nitrate to create an explosive mixture known as ANFO (ammonium nitrate/fuel oil). Ammonium nitrate (NH4NO3) is a widely used explosive and fertilizer compound. When mixed with TNT, it serves as an oxidizer, enhancing the explosive power of the TNT. ANFO is known for its high brisance (shattering effect) and is used in various blasting applications such as mining, quarrying, and demolition. Therefore, the correct compound to mix with TNT for blasting purposes is ammonium nitrate.
