Your point was that a chemical reaction, presumably gas creating, occurs besides the already established effect. The paper you linked just mentions that some dissolved compounds can lower the surface tension which can promote bubble forming. This is not a chemical reaction and the distinction is important.

As far as I know, no one ever says “I sleep at 2100 hrs (twenty-one hundred hours)”. We say “I sleep at 9 o’clock” or “at 21 o’clock”). Then of course change o’clock with your lagnuage’s equivalent such as “uur” or “Uhr” in Dutch and German for example. Pm or am is almost always derived from context, and if it’s not you can add “in the morning/afternoon/evening”.
I don’t really want to spoil too much, but try to invest the coins you get into powerups and try going for relics in the stages (follow green arrow in stages with !). The unlocks screen also has good pointers for what to do next.
Don’t worry about dying quickly if you’re only just started, it’s all part of the game.
