no since nitroge and oxygen are already prevalent in the air all around you
There are small amounts of nitrous oxide in air but it is not a major component (the nitrous oxide has a greenhouse effect). Air is primarily made up of elemental nitrogen and elemental oxygen.
Nitrous oxide sedation is given in the dental chair. Your child will breathe the sedation gas through a small nosepiece that sits on their nose. It does not cover their mouth. The nitrous oxide makes children feel sleepy and relaxed.
There are many known syntheses of phenol. However, a few simple ones are: 1) hydrolysis of chlorobenzene: - chlorobenzene + water --> phenol + hydrochloric acid 2) oxidation of toluene: - toluene + oxygen --> phenol + carbon dioxide + water 3) oxidation of benzene with nitrous oxide: - benzene + nitrous oxide --> phenol + nitrogen
One alternative for the treatment of small areas of detachment is cryopexy, which is performed as an outpatient procedure under local anesthesia. In cryopexy, the ophthalmologist uses nitrous oxide to freeze the tissue underneath the retinal tear.
no modifications necessary
Crack will stay in your saliva about 36-72 hours dependant on the amount
N2O
There is no lead in automotive exhaust. Engine emissions are CO Carbon Monoxide, CO2 Carbon dioxide, O2 oxygen, nitrous oxides and hydrocarbons both raw and partially combusted. However, Back in the day when there were lead in the fuel, car exhaust did emit lead oxide gas.
Atoms are the smallest unit of a single element. Molecules are clusters of atoms bound together, like O2 (oxygen) or NO2 (Nitrous Oxide). Particles are still small, but large enough to reflect light, and usually made of lots of molecules.
Saliva and some enzymes in the small intestine.
Teeth
Saliva is needed for the initial step in the digestion process and the swallowing of food.
