00:01 For this problem we need to classify each of these as ionic molecular or an acid ionic you typically have a metal and a nonmetal you have two ions where they're transferring electrons molecular you it's typically nonmetal nonmetal and then for acids it's usually has an h at the beginning of it.

00:20 So for this first problem.

00:23 We have a metal and a nonmetallic polyatomic ion.

00:28 So this would be ionic and then the name is going to be potassium and then we name the h2po4 which is dihydrogen phosphate kind of a weird name for the next one.

00:46 We actually have a an ion and ammonia polyatomic ammonium polyatomic ion and a dichromate polyatomic ion.

00:55 So this is actually ionic as well.

00:56 The name of this is ammonium di chromate next we have an acid so this is an acid clo is called the hypo chlorite ion ite acids turn into us ite ions turn into us acids eight ions turn into ic acids so ending in ik so since this is hypo chloride.

01:29 It's going to be hypo chlorous acid next we have a metal and a polyatomic ion.

01:41 So this is ionic again.

01:43 So zinc and then nitrate zinc can only have a charge of plus two so we don't need to have a roman numeral for that here we have two non metals.

01:55 So this is the first molecular thing that we have had when we name these we say how many there are so it would be xenon unless there's just one of that first one and then tetra meaning there are four and then fluoride xenon tetrafluoride okay.

02:13 Next we have an acid and this is the acetate ion.

02:18 So eight ions remember turn into ik acids, so this is acetic acid next we have ionic again so we have the nickel ion now nickel can have multiple charges so we need to indicate what the charge is on this if you were to cross these back up this would cross a two this would cross a negative one.

02:42 So it's nickel to chloride next we have another ionic...
