Combustion generally requires at least 16% oxygen in the air for sustained burning. This is known as the oxygen concentration level necessary to support combustion. If the oxygen level falls below this threshold, combustion may not occur or may be incomplete.
The likely word is the gaseous element oxygen.
8 protons comprising the nucleus
Hydrogen's electronegativity is only about 2.1 while oxygen has 3.0, so no.
you use a exygen thromometer, stick it in the water, wait 10 minutes, then see
people need rainforests because they are the lungs of the earth and humans need oxygen and exygen comes from trees and rainforests have lots of trees
it means that the heated circuit decreases time that is needed to enter. When the O2 heater reaches it's right temperature the oxygen sensor commmunicates by switching according to exygen content of the exhaust that surrounds it.
