  • inorganic chemistry - Is Hydrogen Dioxide Water? If so, what is the . . .
    Is Hydrogen Dioxide Water? If so, what is the chemical compound and differences between H2O and H2O2? [duplicate] Ask Question Asked 8 years, 9 months ago Modified 5 years, 10 months ago
  • NH3 + H2O2 - Inorganic Chemistry - Science Forums
    What I am most interested in is what can oxidize NH3 to oxides of nitrogen at room temperature Supposedly, hydrogen peroxide will react with ammonia in the presence of a catalyst, but there seems to be virtually no information about this in the literature (whether the catalyst is iron salts or
  • Gaseous Metals - Inorganic Chemistry - Science Forums
    i know this must be a dumb question, but can metal exist in the gas state? if not then what forces exist that restrict metals from being a gas, i would think it would be the electro-magnetic weak force or universal gravitation
  • inorganic chemistry - Reaction intermediates of MnO2 catalyzed H2O2 . . .
    Manganese dioxide catalyzes the decomposition of hydrogen peroxide to water and oxygen gas But what are the intermediates in this catalyzed reaction?
  • Electrolysis at high vs. low voltages - Science Forums
    Recently I've been trying out some electrolysis, just to observe the results (and catch the occasional bit of hydrogen ), and I'm hoping to start learning much more about chemistry in general, as at the moment I don't really know much about this When I decided to first do the experiment, the onl
  • Do chemists refer to water as dihydrogen monoxide?
    Like most of the other professionals answering here, I've given a couple of talks on international conferences and published some articles in peer-reviewed journals I have never used the terms dihydrogen monoxide or oxidane and do not intend to do so in a serious, scientific context Typically, one talks and writes about water, aqueous solutions and even uses a (traditional) term like brine
  • acid base - What are the products of the dissociation of sodium . . .
    The question should be more specific asking for the ultimate products of the reaction because all these are products of the dissociation of sodium hydrogen carbonate and because are equilibria is probable that all the species are present in different amounts when the reaction reach the equilibrium
  • Demonstrating decomposition of hydrogen peroxide using iron (III . . .
    2 Yes, apart from potassium iodide which is commonly used as a catalyst in the decomposition of hydrogen peroxide, $\ce {Fe^3+}$ salts, manganese dioxide and nickel hydroxide can be used as a catalysts as alternatives Since, iron nitrate contains $\ce {Fe^3+}$, it can be used as catalyst
  • gas laws - Among hydrogen, helium and carbon dioxide, which gas would . . .
    Among hydrogen, helium and carbon dioxide, which gas would behave most like ideal gas and why? [closed] Ask Question Asked 6 years, 6 months ago Modified 6 years, 1 month ago
