(1) aluminium powder and ammonium nitrate Explanation: Ammonal is an explosive made up of ammonium nitrate and aluminium powder. The ammonium nitrate functions as an oxidizer and the aluminium as fuel. The use of the relatively cheap ammonium nitrate and aluminium makes it a replacement for pure TNT. The mixture is affected by humidity because ammonium nitrate is highly hygroscopic. Ammonal is not easily detonated, requiring a fairly substantial shock, though it is still more sensitive than trinitrotoluene and composition C4.
