    Getting Aluminium Chloride from Aluminium & Hydrochloric Acid

    Hi, If I mix aluminium (tin foil) with hydrochloric acid I get the following reaction: 2Al(s) + 6HCl(aq) -> 2AlCl3(aq) + 3H2(g) So I end up with aluminium chloride disolved in the water. If I boiled the water would I be left with pure aluminium chloride? I'm thinking the water...

    Exploring the Reaction Between Na and H2O

    Hi, This isn't really homework, but I'm trying to fully understand the reaction between sodium metal (Na) and water (H2O). Here's the equation: 2Na + 2H2O -> 2NaOH + H2 And here's the steps I think the process goes through: 1) Na has a single electron in its valence shell. This...

    BCC - balancing chemical equations, stoichiometry

    That's interesting. I did some more googling and found these 2 equations, which match what you say, but they don't mention the aluminium oxide: So what happens to the aluminium oxide in the amalgamation process? The reason I'm asking this is because I have some mercury and I want to...

    BCC - balancing chemical equations, stoichiometry

    Hi, I'm trying to write an equation to show what happens when mercury liquid (Hg) is placed on a block of aluminium (Al). But I'm having some problems. Here's my current line of thinking (I haven't yet worked out any subscripts so I will just use the atomic symbols): Al has an aluminium...

    High Voltage and Ozone: Process Overview

    Hi Group, I'm interested in how and why ozone is produced by high voltage discharges. I was hoping that if I give my impression of how the process works, people could correct any mistakes I've made. Here's how I think the process works: 1) Let's pretend a large high voltage arc is...

    Calculating values of the zeta function

    Hi Group, I appologise in advance. My maths knowledge is pretty bad, so some of what I say may not make sense. I'm interested in the Riemann Zeta function, and more specificaly, the Riemann zero's. I'm not trying to prove it, I just want to calculate some of the values. And that's what...
