Nitrous oxide (N₂O), the "laughing gas" used as an anesthetic by dentists, is made by thermal decomposition of solid NH₄NO₃. Wri
AysviL [449]

The balanced equation for the reaction by thermal decomposition of solid are-

                                   N2O (g) + 2 H2O (l) → NH4NO3 (aq)

The NH4NO3 -3, -3 oxidation state. Nitrogen in NO2 (nitrogen dioxide) has an oxidation number of 4. Chemically speaking, ammonium nitrate has the formula NH4NO3. It is a white, crystalline salt made up of nitrate and ammonium ions. Despite not forming hydrates, it is highly soluble in water and hygroscopic as a solid. It is mostly used as a high-nitrogen fertilizer in agriculture. The effects of nitrous oxide depend on how much has been inhaled, and the chemical slows down your brain and body's responses. The effects of nitrous oxide include pleasure, relaxation, and tranquility. Fits of laughter are what give the term "laughing gas" its name.

when the pressure that a gas exerts on a sealed container changes from ____ atm to 2.64 atm, the temperature changes from 315 K
mel-nik [20]

Answer:

1.75 atm

Explanation:

When the pressure that a gas exerts on a sealed container changes from 1.75 atm to 2.64 atm, the temperature changes from 315 K to 475 K.

(2.64 atm) x (315 K / 475 K) = 1.75 atm

The pressure and temperature of a gas in a sealed container are directly proportional. An increase in temperature would imply that the pressure also increased.
