Question

When ammonium nitrate is mixed with aluminum powder, we get ‘ammonal’, which is:
A.An explosive
B.A solvent
C.A paint
D.A dye

Answer 1

Hint: We have to know that ammonium nitrate when mixed with aluminum powder gives ammonal. In ammonal, the main ingredients are aluminum nitrate and aluminum. The main difference between ammonal and Tannerite is that ammonal is a small quantity of charcoal and in Tannerite, a small quantity of charcoal is not present.

Complete answer:
The ammonium nitrate plays the role of an oxidizer and the aluminum acts as fuel. The utilization of the moderately modest ammonium nitrate and aluminum makes it a trade for unadulterated TNT.
Ammonal is an explosive of ammonium nitrate and aluminum powder, not to be mistaken for T-ammonal which contains dynamite also to expand properties like brisance. The combination is frequently alluded to as Tannerite, which is a brand of ammonal.
The blend is influenced by dampness since ammonium nitrate is exceptionally hygroscopic. Ammonal's simplicity of explosion relies upon fuel and oxidizer proportions, 95:5 ammonium nitrate and aluminum being genuinely touchy, anyway not very oxygen adjusted. Indeed, even copper metal follows are known to sharpen mass measures of ammonium nitrate and further increase the threat of unconstrained explosion during a fire, no doubt because of the development of tetramines. More oxygen adjusted blends are not handily exploded, requiring a genuinely considerable stun; however it stays more delicate than dynamite and C-4.
Ammonal is an explosive that is formed by a mixture of ammonium nitrate with aluminum powder.

Option (A) is correct.

Note:
We have to know ammonal is a granular material that is gray-white. It is hygroscopic and non-flammable. When TNT is added, the mixture obtained is T-ammonal. We have to know that ammonal has lower detonation velocity when compared to Tannerite. We have to know that a mixture of T-ammonal is used in shells and hand grenades.
