Now we'll be writing the formulas for some compounds given their names.
00:05
And the first name we have is sodium dihydrogen phosphate.
00:09
No sodium is n -a.
00:11
Dihydrogen tells us that we have two hydrogens, and the polyatomic ion phosphate is p -o -4.
00:20
Since p -o -4 has a 3 -mines charge, and there are two positive hydrogens and one positive sodium, our net charge is zero, and we're all good.
00:30
Next up we have lithium per chlorate.
00:34
Lithium is l -i and has a plus one charge, and per -chlorate is c -l -o -4 with a 1 -minus charge.
00:42
Charges are taken care of, and chloride has four oxygens because it has one more than regular chloride.
00:53
Next we have copper 2, hydrogen carbonate.
00:56
We'll start with copper...
