I know that H2O is called water, and I know water is called H2O. But what would this substance be called if the actual chemical elements were pronounced as they are in other substances, for example CO2 being carbon dioxide?
(I used regular-size numerals because I don’t know how to make small numerals on my computer.)
What you want for H[sub]2[/sub]O is the {sub} coding – you put the code “sub” within square brackets before the characters you want to be subscripted, the 2 in this case, and “/sub” to close it, again in square brackets, after them. You can do the same thing with superscripts: U[sup]239[/sup] by using “sup” instead of “sub.” Finally, you can vary the size of characters in a line without making them subscript or superscript with the “size=” code.
For example: really small text can be mixed with normal text like this, big text, and giant economy size text all in a single line. To get this effect (which you should use sparingly), you code the four sizes (1=small, 2=normal, 3=big, 4=extrabig) as size=1, size=2, etc., within square brackets, turning any of them off with “/size” (no equals and number) within square brackets. The default, of course, is 2 – with no size coding, the whole post is in size=2 font.
I’ve always thought hydrogen hydroxide, for exactly the same reason as Tapioca Dextrin.
But because I’m a geek, I decided to see what Wikipedia has to say about it. Apparently, water has different systematic names depending on whether it’s acting as an acid or a base. When it’s a base, it’s hydrogen hydroxide. When it’s an acid, it’s hydroxic acid or hydroxilic acid. Nasty-sounding stuff!
Most chemists seem to be happy to call it water. Quite disappointing, really. You’d think they’d try harder.
Wow! I just saw the safety notices on that Wikipedia article.
Ouch! But it also says it’s necessary to life, so it’s not all bad.
