Hi, everyone. May I know why carbon dioxide is acidic? Also, will carbon dioxide gas dissolve in water to form hydrogen carbonate? Thanks.

Hi, everyone. I am very confused over these three terms, electromotive force, potential difference and voltage. Just exactly what is the difference between them? Can anyone explain these in simple terms for me? I need to explain it to a bunch of 14 year old but I can't. Also, if you would not mind, please include a more advanced explanation to me. haha. Thank you. I hope the community can reply as fast as possible. ^^
