Thread: Does anyone study Chemistry?

I've took chemistry about three years ago and have pretty much forgotten everything. Anyway can anyone tell me what happens when you combine Magnesium Oxide with Hydrogen Peroxide?

MgO + H2O2 = ???

I heard it explodes, but I don't know why. Some people took the Magnesium Oxide from a few AA batteries and couple of those one dollar bottles hydrogen peroxide and blew themselves up in a Chem class.

Plus don't batteries use Magnesium Dioxide?

MgO2 +H2O2 = ?????

Sorry, no Idea, I threw all my Chem stuff a few weks ago. There was actually a thread like a week ago asking for Chem help as well.

But Magnesium Oxide and Hydrogen Peroxide explodes? Do you know the range and damage it can cause? Sorry, just wondering if it could be a good home-made weapon if I ever need it.

random guess:

MgO + 2 H2O2 = 2 H2O + O2 + MgO.

I took chemistry 2 years ago and purposely forgot everything as soon as I got my AP/SAT's done. So, that's the best I can do for ya. Ask quira.

2MgO + 2H2O2 - > 2H2O + 2O2 + Mg
I think.

can't work.

Mg isn't balanced.

oh.
2Mg, then.

2Mg would turn

2MgO + 2H2O2 - > 2H2O + 2O2 + 2Mg

and simplified into

MgO + H2O2 => H2O + O2 + Mg

hmr.. that works too. I like that betta than my guess. ^_^

Ummm, I think everyone is getting a little ahead of themselves. Doesn't magnesium oxide and water make milk of magnesia?

Checking....



Ah.
From Wiki:

Magnesium oxide is also used in animal feeding industry and there are special grades available. MgO is hygroscopic in nature and care must be taken to protect it from moisture. Magnesium hydroxide (Mg(OH)2) which forms in the presence of water can be reversed by heating to separate moisture.

There you go. Adding water makes antacid, not a bomb.



Edit: Which, of course, is useless, since y'all aren't talking about water. Nevermind. =p

Sorry Jakko, I think you misread wiki...

Either way, that's H20 and not H2O2.

Look up. =p
