To form an exploves, this process will need to react together O2 and NH3 and 5 atmospheres pressure. Futhemore, nitric acid is used to make high explosives such as TNT.

Nitric acid also known as aqua fortis (in 
Latin it mean strong water) and spirit of niter. Is a highly corrosive mineral acid. [nitric acid]
So what is mineral acid, basically it is any acid derived from an inorganic compound that dissociates to produce hydrogen ions in water.

1.  It is used in making explosives such as TNT 
2. It is used to produce ammonium nitrate to manufacture plastic, dye, and fertilizers
3. It is used in liquid-fueled rockets as an oxidizer
4. In its pure forms, it is used in the removal of the wart
5. It is used as a chemical doling agent in electrochemistry ]]> 2021-10-20 23:14:43 UTC https://padlet.com/estherlin7_1/5ljh1hzmzr5q68j8/wish/1831843838 Full Balanced Equation estherlin7_1 https://padlet.com/estherlin7_1/5ljh1hzmzr5q68j8/wish/1831889039 Equation:

It is toxic and can cause severe burns. 

Nitric acid is an acid that has cidic properties. Include a pH less than 7, and have a bitter taste. Sometimes have a violent reaction to other metals. 
Nitric acid is a white, very corrosive, colorless liquid. (Which mean nitric acid is liquid). 

Nitric acid is a strong, monoprotic acid. It readily forms solid hydrates such as the monohydrate (HNO3,H2O), and the (HNO3,3H2O). Nitric acid can be decomposed by heat or light as shown below. 

Which is: 4HNO3 ---> 2H2) + 2H2O + 4NO2 + O2

Durning the reaction, when C7H8 react withC7H7NO2, it needed to include H2SO4, and there is a specific temperature, which is 30 to 40°C . Later on, when C8H10 react with C8H9NO2, it need to include HNO3+H2SO4, and the temperature will be 60°C. Lat but not least, when C8H9NO2 react with C7H5N3O6, it needed to include HNO2+H2SO4, and the temperature will be 110°C . 
- Enzyme activation 
There is no enzyme activation needed in this reaction. 

Principle: 
A more volatile acid can be displaced from its salt by a less volatile acid. This is the basic principle in the laboratory prepration of nitric acid.

    The world largest market for nitric acid is the production of ammonium nitrate and calcium ammonium nitrate. In 2020, nearly 80% of nitric acid was used for fertilizer products[To make a better decision]. Nitric acid is one of the largest commodity chemicals, which is used predominantly as an intermediate for fertilizer production. ]]>     2021-10-21 06:25:52 UTC https://padlet.com/estherlin7_1/5ljh1hzmzr5q68j8/wish/1832669222     Citations estherlin7_1 https://padlet.com/estherlin7_1/5ljh1hzmzr5q68j8/wish/1832675877
