Gee, thanks for the help. What kind of a site is this??? Every time I ask a question I always get a smart ass answer. I guess I'll go somewhere else to get help because you people are useless. And no this isn't homework.

What happens when you put these things together and what's the equation for them and what type of reactions are they? 1. Water and ammonium chloride 2. Hydrogen peroxide and magnesium dioxide 3. Calcium chloride and Sodium Carbonate 4. Hydrochloric acid and a piece of magnesium ribbon. Thank You so much.

OKay so i'm kind of stupid and I don't understand where the 2 comes from. How do you get a 2? If nickel is a transitional metal and has 2 different charges of 2 or 3 how do you know that it's a 2 in NiCl2 if Chlorine has a charge of 1? Shouldn't it be NiCl ? I'm really confused and i hope that someone can explain this to me. Hopefully that this has made some sense.

well I mean that the element or whatever doesn't get bigger or smaller so how can the radius decrease?

I'm really confused about something. I don't understand why the atomic radius decreases left to right on the periodic table if the atom doesn't get bigger. Can someone please explain this to me. So i was told that the atomic radius is the distance from the nucleus to the outer shell but since everything is the same when you go from left to right i don't get it.

I'm new here and i'm kind of stupid so please be nice to me lol. Anyways, here's my question: Is Cl2 a covalent compound or a molecular compound? What's the difference between them? Thanks
