Popular questions
What is a hydrogen bond?
A hydrogen bond is a weak electrostatic attraction between a hydrogen atom bound to an electronegative atom (like O, N, or F) and another electronegative atom; it’s unrelated to E949, which is hydrogen gas used mainly as a packaging/propellant additive.
Does hydrogen peroxide expire?
Yes—household hydrogen peroxide (not E949) slowly decomposes to water and oxygen; unopened it typically lasts up to about a year in a cool, dark place, but after opening it’s best used within 1–3 months.
Is hydrogen water good for you?
Hydrogen water is water infused with dissolved hydrogen gas (E949); it’s generally safe, but evidence for meaningful health benefits is limited and not conclusive.
Is hydrogen a metal?
No—hydrogen is a nonmetal under standard conditions; as E949 it’s the colorless, flammable gas used as a food-packaging/propellant additive.
Does hydrogen peroxide kill mold?
3% hydrogen peroxide can kill mold on hard, nonporous surfaces, but it’s less effective on porous materials like wood or drywall; use in a ventilated area and don’t mix it with bleach or vinegar.
Is nitrogen oxide a greenhouse gas?
Nitric oxide (NO), often called “nitrogen oxide,” is not considered a significant greenhouse gas; nitrous oxide (N2O, a different nitrogen oxide used as E942) is a potent greenhouse gas.
What is the formula for nitrogen oxide?
The common “nitrogen oxide” in this context is nitric oxide, with the formula NO (other nitrogen oxides include NO2 and N2O).
Where does nitrogen oxide come from?
It’s formed during high‑temperature combustion (e.g., engines, power plants) and produced industrially by catalytic oxidation of ammonia (Ostwald process).
Is nitrogen oxide harmful?
Yes—NO and NO2 are respiratory irritants, and high exposures can damage the lungs; they are regulated air pollutants.
What does a catalytic converter turn nitrogen oxide into?
Automotive three‑way catalytic converters reduce NOx primarily to nitrogen (N2) and oxygen (O2), often yielding N2, CO2, and H2O using CO and hydrocarbons as reductants.
