AnswersFollowing are the reasons why hydrogen H 2 gas is not evolved when most metals react with nitric acid HNO 3: Nitric acid is a strong oxidizing agent When a metal reacts with Nitric acid, it oxidizes the Hydrogen to produce water H 2 O Nitric acid reduces itself to any of the Nitrogen oxides (N 2 O, NO) after oxidizing the HydrogenWhy is hydrogen gas not evolved when most of the metals react 2020年6月13日 This question is derived from a question asked in my school test What happens when a magnesium ribbon is heated in air? My first response was the formation of magnesium oxide $(\ce{MgO})$ when oxygen in air reacts with magnesium at a high temperature which can be expressed in the form of a chemical equation like this: $$\ce{2 Mg(s) + O2(g) >[\Delta] 2 On heating in the Earth's atmosphere, can magnesium react with nitrogen

Is it because the $\ce{NO2}$ group really "wants" to be $\ce{N2}$ since a) diatomic nitrogen has a super high bond strength and b) diatomic nitrogen is a gas usually and therefore conversion to diatomic nitrogen would be entropically favorable organic chemistry Why do nitro groups confer explosive tendencies In this way, nitrogen does not need to return to a gas Under conditions when there is no oxygen, some bacteria can reduce nitrates to molecular nitrogen Usable nitrogen is sometimes the factor that limits how many organisms can The Carbon Cycle and the Nitrogen Cycle Earth Inertness: Nitrogen is an inert gas, meaning it does not react chemically with other substances This inertness makes nitrogen ideal for use in an accumulator as it does not react with the hydraulic fluid or other components By using nitrogen, the risk of corrosion or degradation of the accumulator components is reducedWhy Nitrogen is Used in Accumulator Plug IN Highway
