    Hello,
    I'm currently revising thermal decomposition. In an experiment we performed in class, our last step after making Limewater was to blow bubbles through it with a straw. I also know that to create Calcium Carbonate again, carbon dioxide needs to be bubbled through Limewater, also forming water. So is the last step - blowing though a straw into the Limewater - creating Calcium Carbonate? Because wew breathe out a small amount of carbon dioxide, so is that what that step is there for? Or do I need to separately bubble carbon dioxide through limewater.
    Thankyou, I hope you understood my question

    Blowing bubbles will produce calcium carbonate, this part is OK.
