It looks like for this question you're given the name of the acid and you're asked to write the correct chemical formula.
00:07
The first one is phosphoric acid.
00:12
Because it doesn't begin with the word hydro, that means oxygen is in the formula, and the phosphoric came from phosphate.
00:20
8 turns into ick when we write it as an acid.
00:25
So, phosphate is p .043 minus.
00:29
That means we're going to need three hydrogens to cancel the three minus charge.
00:34
The next one is hydrochloric acid because we have the prefix hydro.
00:42
There is no oxygen in the formula.
00:45
The chloric came from chloride.
00:47
Chloride is just chl minus.
00:50
So we just need one hydrogen to cancel the one minus charge...
