The Five Major Class of Chemical Reactions

[gingerpeachus]

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.

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

[OldSmashbones]

@InfuserGod u mean a centrifuge?

[InfuserGod]

@OldSmashbones YES! Thank you! =]

shouldn't he wear gloves when using the mercury compound

[djkonflikt713]

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

[Masalmeh321]

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

Similar valencies aren't writen...

[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]

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

[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.

hello Omnibu class!

[kcnep]

chemistry in action!

[hanzo8120]

Looks intresting. But I was never good in Chemical things.

That video adds a little confusion to the basics of combustion. Although chemicals outside the organic compound, 02, CO2, and H2O can be used, happens in more advanced organic chemistry. The simplest to think about it is

CxHxOx + O2 --> CO2 + H2O

cool thanx for the help i need this for school
