This is a good video for showing the different types of chemical reactions very quickly. Adding the balanced equations to this video would be great, but I plan to have my students write and balance these equations in class.

@OldSmashbones YES! Thank you! =]

[OldSmashbones]

@InfuserGod u mean a centrifuge?

1:40 I know this may sound stupid: but what are those spinning vial holders called?

[PennyDorkis]

what obscurusvita should have said is that Mercury(I) doesn't usually come as a single atom/ion

When Mercury has a charge of +1, it likes pairing up with another mercury ion of charge +1. They do not like being alone.

Yes, what you said is right for other elements, but for mercury it is only right in very special circumstances.

shouldn't he wear gloves when using the mercury compound

whose the narrator whats his name? I need it to give credit to this guy. anyone know?

So in a single valency, HgNO3. In a double valency, Hg(NO3)2. So what I'm saying is right.

[obscurusvita]

Hg2(NO3)2 is Mercury with a +1 charge BUT Mercury(I) is a diatomic ion as

Hg2 +1 so it's true charge is +2 not +2 therefore you need 2 NO3 ions.

Mercury(II) nitrate would be Hg(NO3)2 ...the Hg2+ ion is monoatomic

[Masalmeh321]

Umm, Hg2(NO3)2? Isn't it HgNO3?

Similar valencies aren't writen...
