  • I know that H+ is not possible in water and it is present as H3O+. But later on I come to know that even H3O+ is not possible and that it is present as H9O4+. Why does this happen? What give that comp...

  • This is a question that has been bugging me for over 15 years! In high school while studying elements our teacher showed us a clear white rock or element. It was simply flat on both sides but when pl...

  • I've read how putting a burning piece of sodium in chlorine would produce white NaCl fumes. However, I can't find out whether Na or Li can react with Cl₂ without heating or burning.

  • Liquid nitrogen seems to be attracting a bit of attention at the moment as a medium of energy storage, both for electricity grid applications and for transport. For example, Highview are doing round-...

  • Can you tell me what's the nomenclature of $\ce{C H_2 O_2}$? What is its IUPAC name?

  • Ok, this is a simple problem, but I cant see how to get the answer. I calculated the activity coefficient, $\gamma_\pm$ = 0.389, and I need to find the activity $a_\pm$ for a 0.0120m solution of $Na_3...

  • Looking for the structure of 2-methylimidazolate, I find conflicting results: this page on sodium 2-methylimidazolate gives: this other page on cadmium 2-methylimidazolate gives another anion, name...

  • Is it possible to heat a material above its solidus without melting occurring? More specifically, at a heating rate of approximately 200K/s, will a metal alloy exhibit superheating and if so by what ...

  • Titration experiment Sherry Eskandarian

    I need to find the concentration of $\ce{KMnO4}$ as it is an unknown. It is a titration experiment between $\ce{KMnO4}$- and sodium oxalate solution I assumed I had $25.00ml$ of $0.01003 M$ of $\c...

  • In an experiment we conducted, we heated 1.6 grams of copper dust, and got 1.7 grams of oxidised copper, (it probably reacted with 0.1 grams of $O_2$) and our goal was to find which of the two forms, ...

  • Is there an online database of acid and basic dissociation constants, all in one place, free to use?

  • Sorry if this is not the place for asking this question, but I'm going to do a real life project and don't know where else to ask. I'm going to prepare and sell snow cones next summer. For making sno...

  • I'm searching for the products to the following reactions: $$\ce{CoO + MgO -> } \small\text{(cobalt pink)}$$ $$\ce{CoO + SnO -> } \small\text{(cobalt green)}$$ I know that corresponding reactio...

  • What are some white compounds that look like powder (like flour) and immediately black after being heated? It turns immediately black and creates a odorous gas. Thanks!

  • EDTA (Ethylenediaminetetraacetic acid) has a structure like this But why, as the name 'Ethylene' suggests, doesn't it should have a double bond between carbons?

  • What is fire? Is it a material or energy or something else? Please explain it to me. My friend asked me this. I am stuck with this problem.

  • equation 1) $\ce{2 Cl^{–} -> Cl_2 + 2e^{-}}$ equation 2) $\ce{2 H2O + 2 e^{–} -> H2 + 2OH^{–}}$ These equations are the key reactions in the chlor-alkali process. I want to model a reactor f...

  • By compressing $\ce{CO2 (g)}$ the gas gains a lot of heat. When the hot compressed carbon dioxide is left to cool, it attains the temperature of the surrounding material. When it is released into the ...

  • First, I would like to say that I understand the basic idea of disassociation and solubility. However, as I study intermolecular forces I feel like this basic Idea is being challenged. My understandin...

  • The bonds are: (I have given pictures of what I mean in case there's any ambiguity that I leave open in these questions. Also so that if you want to number the R groups you've got a head-start) Seco...
