2009年2月24日 · No, there isn't. H 2 S and H 2 O are in intimate contact in volcanic processes that occur naturally, and there isn't a reaction between them. To make H 2 SO 4 one needs to make SO 3 first, which requires O 2 and something to initiate a combustion reaction. SO 3 dissolved in liquid H 2 O makes H 2 SO 4. _____

2009年7月14日 · What would the galvanic reaction be if i put stainless steel 3042b against aluminum part in an outdoor application with the possibility of a slat water spay against it in a typical weather year. what would it be in a non salt water spray environment. Would it be wise to anodize the aluminum or what other applications would be considered.

2010年10月30日 · No chemical reaction will take place through steam. We use killed steel for low temp. service due to its higher impact strength at lower temperatures as compared to ordinary steel. If you are talking about piping, A-106 Gr.B or API-5L Gr. B seamless quality of piping along with corresponding fittings, flanges, etc. are suitable for the above ...

2019年1月12日 · The last link you provide states that both citric acid and ferric citrate can be poured down the drain if less than 5 gallons , or if greater than 5 Gal then seek advise on disposal through a specialist waste disposal company.

2024年5月21日 · As DEF enters the system, it evaporates into ammonia (NH₃) and water (H₂O), the ammonia sticks on the SCR catalyst and binds with the nitrogen oxides as they pass over the catalyst. Once bound, the nitrogen oxides will combine with the ammonia to create a chemical reaction resulting in nitrogen and water. (NO+NO₂+2NH₃ -> 2N₂ + 3H₂O)

2007年8月22日 · Is the cable immersed in the water for a great length? I am puzzled at what the mechanism is that you think ties the cable to the chemical reaction. It certainly is'nt providing the sulfur. As others have mentioned changing the cable is no big deal,. but it is not likely to make the smell go away. I would have the well water tested commercially ...

2007年4月9日 · Absorption of a chemical (along with possible chemical reaction ) may take place typically by a medium with a large surface area (although the technical interaction my also involve surface adsorption (not strictly absorption), but it usually due to the absorbed chemical entering into voids and being trapped there, since diffusion out of those ...

2013年8月28日 · The chemical formula for PCBs is C12H10-xClx, where x = 1-10. PCB's were widely used for many applications, especially as dielectric fluids in transformers and capacitors and coolants. Due to PCB's toxicity and classification as persistent organic pollutants, PCB production was banned by the United States Congress in 1976 and by the Stockholm ...

2012年5月6日 · Some exothermic chemical reaction which results in more gas molecules in the products than in the reactants, would illustrate Le Chatelier's Principle in action i.e. the system tries to oppose the constraint (drop in pressure) by producing more molecules.
