    Set up 2 apparatus and for each experiment use one brand and another bran for the other experiment. Then heat it and the carbon dioxide will pass through the delivery tube into the test tube with lime water in it. Check what test tube is cloudier and the cloudier one will hav more carbon dioxide since lime water turns carbon dioxide cloudy.
    I talked about that limewater thing as well, But never gave a description of the experiment.
    I said something about density as well.

    For the Strontium one I wrote about it as a radioisotope

    What did everyone get for the what type of reaction is it at beaker B and the other reaction one?
    Oxidation for beaker B wasn't it?

    I'm pretty sure that 0.36 litres is right as the balanced equation above the question showed 2Al to 3H2
    Sure ? Don't lull me into a false sense of security

    I think it was but I wrote reduction, I had oxidation then changed it to reduction :/
    What about the other chemical reaction I got addition

    For the last using your knowledge q what did everyone put down?

    I'm sure as it was what I got and was one of the questions that stumped me for a moment before I got it.

    My workings were something similar to:
    1 mole H2 = 24 L
    Al = 0.01 moles
    Al : H2
    2 : 3
    5 parts so 1 part = 0.01/2 = 0.005
    3 x 0.005 = 0.015
    Final answer = 24 x 0.015 = 0.36 L

    I got the same exact working and final answer as you Frank

    Its a metal. It loses to electrons to become positive. To test for strontium heat it and see if the flame colour turns watever colour it said in the data booklet. Density, and cant rmbr

    That's comforting! It was definitely one of the more harder questions in the paper for me

    Yeah I done mostly the same as you, But forgot about the flame test lol

    What did people say for the question about what the sodium ion solution thing acted as? I put conductor but I know it's wrong now, was it electrolyte?

    Since it's a metal it's shiny, it has high melting and boiling points, it conducts electricity because of free moving ions and it has a red flame colour

    I wrote electrolyte, I think

    Yeah, that's what I put because:
    2mol Al ---> 3 mol H2
    1mol Al ---> 1.5 mol H2
    0.01 mol Al ---> 0.015 mol H2
    0.015 mol H2 = 0.015 * 24 = 0.36 litres

    Strong then weak But I think I'm wrong. I was confused
