Urea to Ammonium nitrate

Using silver nitrate to turn urea into silver nitrate and ammonium nitrate

Silver nitrate reacts with urea to form silver cyanate
Tge sil

And interesting reaction occurs with nitric acid
Silver cyanate forms carbon dioxide, silver nitrate and ammonium nitrate

Is this better aga
https://en.m.wikipedia.org/wiki/Silver_cyanate
It can be prepared by the reaction of potassium cyanate or urea with silver nitrate.

AgNO3 + KOCN -> AgOCN v + KNO3
It can be prepared by the reaction of potassium cyanate or urea with silver nitrate.

AgNO3 + H2N-C(O)-NH2 -> AgOCN v + NH4NO3

AgOCN + HNO3 -> AgNO3 + NH4NO3 + CO2

The silver nitrate acts as a catalysis in this process
orming more silver nitrate this process consumes urea and nitric acid but does not combine them forming urea nitrate

This process maininy produces ammonium nitrate from urea


Urea and silver nitrate
Ammonium nitrate

Urea nitrate and sodium hydroxide
Ammonia and sodium nitrate

Urea nitrate and calcium hydroxide
Calcium carbonate
ammonium nitrate

This process could be used to make nitric acid

Similar to a path using potassium permanganate
In which some is consumed in a 2 steps forward and 1 step back kind of process

Ummm, what ?

Are you proposing something you want to do, or just wanking off while using the words 'urea', 'silver nitrate' and 'nitric acid' ?

I'm not knocking it - whatever gets you off is fine - just the post is incomprehensible.

Is there a name for that type of paraphilia? Perhaps chemophilia

Would being sexually aroused by complicated glassware be called vitrophilia.

Power tools work for me https://www.youtube.com/watch?v=a0fkNdPiIL4 It may be the workwomen LOL

But wiki lists a different reaction...
Quote:

Silver cyanate is a chemical compound; it is the cyanate salt of silver. It can be prepared by the reaction of potassium cyanate or urea with silver nitrate.[1] $$AgNO_{3} + KOCN ⟶ AgOCN ↓ + KNO_{3}$$ $$AgNO_{3} + H_{2}N−C(O)−NH_{2} ⟶ AgOCN ↓ + NH_{4}NO_{3}$$ Silver cyanate is a beige to gray powder. It crystallises in the monoclinic crystal system in space group P21/m with parameters a = 547.3 pm, b = 637.2 pm, c = 341.6 pm, and β = 91°.[2] With nitric acid, silver cyanate reacts to form silver nitrate, carbon dioxide, and ammonium nitrate.[3] $$AgOCN + 2 HNO_{3} + H_{2}O ⟶ AgNO_{3} + CO_{2} ↑ + NH_{4}NO_{3} $$


Count again. No nitrate ions are created.

Your right no new nitrate ions only a conversion
Of urea to ammonium nitrate maybe aga is right I got excited to see urea oxidized chemically to a nitrate salt the better way would be if urea at least there is a way to make a concentrated ammonium nitrate solution

In this reaction urea acts like ammonium carbonate
